High strain rate behaviour of Aluminium alloy processed by Selective Laser Melting

Selective Laser Melting (SLM) is a layer-by-layer metal additive manufacturing process. Parts processed by SLM can be subjected to severe dynamic loadings and high temperature in service, in applications such as defence, aerospace, automotive and high-speed machining. Very few studies have reported on the behaviour of additively manufactured metal parts subjected to high strain rate loading conditions. This thesis is focused on studying the mechanical behaviour of SLM-processed and heat treated AlSi12 aluminium alloy parts under quasi-static and dynamic compression. Furthermore, the present studies provide an insight into tests conducted at elevated temperature and at heat-treated conditions for AlSi12 aluminium alloy.
