text: Due to current global challenges regarding energy security as well as climate
change the importance of preserving the nature and all available resources is
steadily increasing. In order to achieve the energy-saving and climate targets,
it is not only necessary to develop new processes and processing possibilities,
but also to optimise known process chains with regard to energy and resource efficiency
in the area of production technology. Here, the recycling of supposed production
waste represents an opportunity to save energy. In addition to the conventional
and smelting metallurgical recycling process, extensive research activities have
therefore been carried out for alternative solid-state recycling processes. One
example is the friction-induced recycling process, which has been used in past
studies to demonstrate the energy- and resource-efficient production of semi-finished
products from aluminium scrap such as chips. In addition, properties like chemical
composition and strength can be adjusted locally and in terms of processing time.
This can be used to improve the versatility of further processing steps.

text: AbstractEfforts to enhance sustainability
in all areas of life are increasing worldwide. In the field of manufacturing technology,
a wide variety of approaches are being used to improve both resource and energy
efficiency. Efficiency as well as sustainability can be improved by creating a
circular economy or through energy-efficient recycling processes. As part of the
interdisciplinary research group "Light—Efficient—Mobile" investigations on the
energy-efficient friction-induced recycling process have been carried out at the
department of Forming and Machining Technology at Paderborn University. E.g. using
the friction-induced recycling process, different formless solid aluminum materials
can be direct recycled into semi-finished products in an energy-efficient manner.
The results of investigations with regard to the influence of the geometrical
shape and filling rate of the aluminum particles to be recycled as well as the
rotational speed of the continuously rotating wheel are explained in this paper.
In addition to the recycling of aluminum chips, aluminum particles like powders
from the field of additive manufacturing are processed. Based on these results,
the future potentials of solid-state recycling processes and their contribution
to the circular economy are discussed. The main focus here is on future interdisciplinary
research projects to achieve circularity in the manufacturing of user-individual
semi-finished products as well as the possibility to selectively adjust the product
properties with the continuous recycling process.

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.
