Integrated Computational Materials, Process and Product Engineering – IC-MPPE 2022

Titanium alloys are used in many applications in aerospace jet engines from compressor blades through to critical rotating discs, each application having its own unique mechanical integrity requirements. Feedback from full scale component testing and service operation can be used to inform alloy composition and manufacturing routes for the future. Utilisation of a multiscale approach is vital...

Compositionally Complex Alloys (CCAs) are a part of the High Entropy Alloy (HEA) concept, which currently draws much attention from both fundamental and applied research perspectives. For advanced high temperature applications, these alloys, strengthened by intermetallic particles, show high potential for replacing some types of state-of-the-art Ni-based superalloys in the future. Such alloys...

There are a number of applications where materials are exposed to high temperatures and mechanical loads combined with specific environmental conditions. Applications are e.g. high temperature tooling which require materials combining oxidation resistance, high temperature strength and hardness as well as resistance against creep. The use of advanced materials in re-entry applications can be...

Oxide-dispersion strengthened materials exhibit improved high temperature mechanical properties such as strength and creep resistance. However, their production via mechanical alloying is not only time-consuming and thus expensive but also in some cases difficult to implement. Therefore, in order to improve the efficiency of the mechanical alloying process, cryomilling was investigated for the...
