text: Through tailoring the geometry and design of biomaterials, additive
manufacturing is revolutionizing the production of metallic patient-specific implants,
e.g., the Ti-6Al-7Nb alloy. Unfortunately, studies investigating this alloy showed
that additively produced samples exhibit anisotropic microstructures. This anisotropy
compromises the mechanical properties and complicates the loading state in the
implant. Moreover, the minimum requirements as specified per designated standards
such as ISO 5832-11 are not met. The remedy to this problem is performing a conventional
heat treatment. As this route requires energy, infrastructure, labor, and expertise,
which in turn mean time and money, many of the additive manufacturing benefits
are negated. Thus, the goal of this work was to achieve better isotropy by applying
only adapted additive manufacturing process parameters, specifically focusing
on the build orientations. In this work, samples orientated in 90°, 45°, and 0°
directions relative to the building platform were manufactured and tested. These
tests included mechanical (tensile and fatigue tests) as well as microstructural
analyses (SEM and EBSD). Subsequently, the results of these tests such as fractography
were correlated with the acquired mechanical properties. These showed that 90°-aligned
samples performed best under fatigue load and that all requirements specified
by the standard regarding monotonic load were met.

text: AbstractRolling processes of conventional
cast Al-Li alloys quickly reach their limits due to relatively poor material formability.
This can be overcome by using twin-roll casting to produce thin sheets. Further
thermomechanical treatment, including hot or cold rolling, and heat treatment
can adjust the mechanical properties of twin-roll cast Al-Li sheets. The whole
manufacturing chain requires detailed knowledge of the precipitation and dissolution
behavior during heating, soaking and cooling, to purposefully select any process
parameters. This study shows the process chain of a twin-roll cast Al–Cu–Li alloy
achieving a hardness of around 180 HV1 by adapting the heat treatment parameters
for homogenisation, hot rolling and age hardening. Both hardness and microstructure
evolution are visualised along the process chain.
