Microstructure and Mechanical Properties of Al-Li Alloys with Different Li Contents Prepared by Selective Laser Melting.

Research on the development of new lightweight Al-Li alloys using a selective laser melting process has great potential for industrial applications. This paper reports on the development of novel aluminum-lithium alloys using selective laser melting technology. Al-Cu-Li-Mg-Ag-Sc-Zr pre-alloyed powders with lithium contents of 1 wt.

Microstructure, Mechanical Properties and Fracture Behavior of Micron-Sized TiB/AlZnMgCu(Sc,Zr) Composites Fabricated by Selective Laser Melting.

In this paper, micron-sized TiB/AlZnMgCu(Sc,Zr) composites were fabricated by selective laser melting (SLM) using directly mixed powder. Nearly fully dense (over 99.5%) and crack-free SLM-fabricated TiB/AlZnMgCu(Sc,Zr) composite samples were obtained and its microstructure and mechanical properties were investigated.
