Effects of Heat Treatment on Compressive Behavior of Porous Aluminum Manufactured by SLM

Abstract:

Porous Al-10Si-0.3Mg alloys are produced by 3D Selective Laser Melting (SLM). The samples with 90, 93 and 96% porosities consist of octahedron unit cells. As-built samples showed low energy absorption property due to their brittle fractures. The samples after isothermal holding at 803 K for 6 h showed high energy absorption property. Dendrite silicon phase in as-built samples probably caused brittle fracture of the struts. Moreover, the authors considered that SHT samples are lack of stability on mechanical properties and investigated energy absorption property of aging samples. Hardness of the struts increased after aging at 280, 473 and 523 K. Overaging treatment is effective to increase the plateau region at the expense of strength.
