#15931, Static and Fatigue Behaviour of Recycled Thin Sheet “Ti-Al-Nb” based Composites produced by Hot Forging Diffusion Process

In the frame of the common research project, the mechanical properties and fatigue behaviour of recycled thin sheet Ti-Al based composites reinforced with atomized scrap aluminium (AA7075) and Nb elements have been evaluated. Thin sheet sandwich structures were produced by Thixoforming process, a semi-solid forming process similar to partial melting hot forging.
The effects of chemical bonds during the production of these multifunctional sandwich composite structures were analyzed by 3 Point Bending (3PB) tests under static and dynamic (fatigue) loading conditions. Additional tensile tests have been carried out to evaluate mating effect. Interface and microstructure of these composites have also been evaluated by Scanning Electron Microscope (SEM).
