text: Modern forming processes often allow today the efficient production
of complex parts. In order to increase the sustainability of forming processes
it would be favorable if the forming of workpieces becomes possible using production
waste. At the Chair of Forming and Machining Technology of the Paderborn University
(LUF) research is presently conducted with the overall goal to produce workpieces
directly from secondary aluminum (e.g., powder and chips). Therefore, friction-based
forming processes like friction spinning (or cognate processes) are used due to
their high efficiency. As a pre-step, the production of semi-finished parts was
the subject of accorded research work at the LUF. Therefore, a friction-based
hot extrusion process was used for the full recycling or rework of aluminum chips
into profiles. Investigations of the recycled semi-finished products show that
they are comparable to conventionally produced semi-finished products in terms
of dimensional stability and shape accuracy. An analysis of the mechanical properties
of hardness and tensile strength shows that a final product with good and homogeneously
distributed properties can be produced. Furthermore, significant correlations
to the friction spinning process could be found that are useful for the above-mentioned
direct part production from secondary aluminum.

text: Driven by the CO2-emission law by the European government and the increasing
costs for raw materials as well as energy, the automotive industry is increasingly
using multi-material constructions. This leads to a continuous increase in the
use of mechanical joining techniques and especially the self-piercing riveting
is of particular importance. The reason for this is the wide range of joining
possibilities as well as the high load-bearing capacities of the joints. To be
able to react to changing boundary conditions, like material thickness or strength
variation of the sheets, research work is crucial with regard to the increase
of versatility. In this paper, a numerical study of the influences on the selfpiercing
riveting process is presented. For this purpose, the influence of different process
parameters such as rivet length and die depth on various quality-relevant characteristics
were investigated. With the help of the design of experiment, significant influences
were determined and interactions between the individual parameters are shown.

text: In many areas of product manufacturing constructions consist of individual
components and metal sheets that are joined together to form complex structures.
A simple and industrial common method for joining dissimilar and coated materials
is clinching. During the joining process and due to the service load cracks can
occur in the area of the joint, propagate due to cyclic loading and consequently
lead to structural failure. For the prevention of these damage cases, first of
all knowledge about the fracture mechanical material parameters regarding the
original material state of the sheet metals used within the clinching process
are essential.Within the scope of this paper experimental and numerical preliminary
investigations regarding the fracture mechanical behavior of sheet metals used
within the clinching process are presented. Due to the low thickness of 1.5 mm
of the material sheets, the development of a new specimen is necessary to determine
the crack growth rate curve including the fracture mechanical parameters like
the threshold against crack growth ΔKI,th and the fracture
toughness KIC of the base material HCT590X. For the experimental
determination of the crack growth rate curve the numerical calculation of the
geometry factor function as well as the calibration function of this special specimen
are essential. After the experimental validation of the numerically determined
calibration function, crack growth rate curves are determined for the stress ratios
R = 0.1 and R = 0.3 to examine
the mean stress sensitivity. In addition, the different rolling directions of
0° and 90° in relation to the initial crack are taken into account in order to
investigate the influence of the anisotropy due to rolling.

text: AbstractIn addition to the classical strength
calculation, it is important to design components with regard to fracture mechanics
because defects and cracks in a component can drastically influence its strength
or fatigue behavior. Cracks can propagate due to operational loads and consequently
lead to component failure. The fracture mechanical analysis provides information
on stable or unstable crack growth as well as about the direction and the growth
rate of a crack. For this purpose, sufficient information has to be available
about the crack location, the crack length, the component geometry, the component
loading and the fracture mechanical material parameters. The fracture mechanical
properties are determined experimentally with standardized specimens as defined
by the guidelines of the American Society for Testing and Materials. In practice,
however, especially in the context with damage cases or formed material fracture
mechanical parameters directly for a component are of interest. However, standard
specimens often cannot be extracted at all due to the complexity of the component
geometry. Therefore, the development of special specimens is required whereby
certain arrangements have to be made in advance. These arrangements are presented
in the present paper in order to contribute to a holistic investigation chain
for the experimental determination of fracture mechanical material parameters
with special specimens.

text: Powder X-ray diffraction (XRD) patterns of ordered mesoporous CMK-8 and CMK-9
carbon materials are simulated by geometric modeling. The materials are amorphous
at the atomic length scale but exhibit highly symmetric gyroidal structures at
the nanometer scale, corresponding to regular, continuous nanopore systems with
cubic symmetry. Their structures lead to characteristic low-angle XRD signatures.
We introduce a model based on geometrical considerations to simulate CMK-8 and
CMK-9 structures with variable volume fraction of carbon (vs. pore volume, i.e.,
variable 'pore wall thickness'). In addition, we also simulate carbon materials
with variable amounts of guest species (e.g., sulfur) residing in their pores.
The corresponding XRD patterns are calculated. The carbon volume fraction turns
out to have a significant impact on the relative diffraction peak intensities,
especially in case of CMK-9 carbon that features a bimodal porosity. Likewise,
the presence of guest species in the pores may also strongly affect the relative
peak intensities. Our study suggests that careful evaluation of experimental low-angle
XRD patterns of (real) CMK-8 or CMK-9 materials offers an opportunity to obtain
detailed information about the nanostructural properties in addition to the mere
identification of the pore systems geometry.

text: A comparison of infrared spectroscopic analytical approaches was made in order
to assess their applicability for internal structure characterization of SiO2
thin films. Markers for porosity and/or disorder based on the analysis of the
asymmetric stretching absorption band of SiO2 between 900−1350 cm−1 were discussed.
The shape of this band, which shows a well-defined LO–TO splitting, depends not
only on the inherent characteristics of the film under analysis but also on the
particular geometry of the IR experiment and the specific surface selection rules
of the substrate. Three types of SiO2 thin films with clearly defined porosity
ranging from dense films to mesoporous films were investigated by transmission
(at different incidence angles), direct specular reflection (at different angles),
and diffuse reflection. Two different types of substrate, metallic and semiconducting,
were used. The combined effect of substrate and specific technique in the final
shape of the band, was discussed, and the efficacy for their applicability to
the determination of porosity in thin SiO2 films was critically evaluated.

text: Tailor-made ordered mesoporous materials bear great potential in numerous
fields of application where large interfaces are required. However, the inherent
surfacechemical properties of conventional materials, such as silica, carbon or
organosilica, poses some limitations with respect to their application. Surface
manipulation by functionalization with chemically more reactive groups is one
way to improve materials for their desired purpose. Another approach is the design
of high surface-area composite materials. The surface manipulation, either by
functionalization or by introducing guest species, can be performed selectively.
This means that when several distinct, i.e. , hierarchical, types of surfaces
or pore systems exist in a material, each of them may be chosen for manipulation.
Several strategies can be identified to achieve this goal. Molecules or molecule
assemblies can be utilized to temporarily protect pores or surfaces (soft protection),
while manipulation occurs at the accessible sites. This approach is a recurring
motive in this review and can also be applied to rigid template matrices (hard
protection). Furthermore, the size of functionalization agents (size protection)
and their reactivity/diffusion (kinetic protection) into the pores can also be
utilized to achieve selectivity. In addition, challenges in the synthesis and
characterization of selectively manipulated ordered mesoporous materials are discussed.

text: In this report, a flame spray pyrolysis setup has been examined with various
in situ extraction methods of particle samples along the flame axis. First, two
precursor formulations leading to the formation of iron oxide nanoparticles were
used in a standardized SpraySyn burner system, and the final particle outcome
was characterized by a broad range of established powder characterization techniques
(TEM/HRTEM, SAXS, XRD, BET). The characterization of the powder products evidenced
that mostly homogeneous gas-to-particle conversion takes place when applying an
acidic precursor solution, whereas the absence of the acid leads to a dominant
droplet-to-particle pathway. Our study indicates that a droplet-to-particle-pathway
could be present even when processing the acidic formulation. However, even if
a secondary pathway might take place in this case as well, it is not dominant
and nearly negligible. Subsequently, the in situ particle structure evolution
was investigated for the dominant gas-to-particle pathway, and particles were
extracted along the flame axis for online SMPS and offline TEM/HRTEM analysis.
Due to the highly reactive conditions within the flame (high temperatures, turbulent
flow field, high particle number concentrations), the extraction of representative
samples from spray flames is challenging. In order to handle the reactive conditions,
two extraction techniques were tailored in this report. To extract an aerosol
sample within the flame for SMPS measurement, a Hole in a Tube probe was adjusted.
Thus, the mobility particle diameter as well as the corresponding distribution
widths were obtained at different heights above the burner along the flame axis.
For TEM/HRTEM image analysis, particle samples were collected thermophoretically
by means of a tailored shutter system. Since all sampling grids were protected
until reaching the flame axis and due to the low sampling time, momentary captures
of local particle structures could be extracted precisely. The particle morphologies
have clearly shown an evolution from spherical and paired particles in the flame
center to fractal and compact agglomerates at later synthesis stages.
