Abstract

Objective: To evaluate the tensile and compression behaviour of Al-Si10-Mg alloy developed by selective laser melting (SLM) process. Method: Al-Mg10-Si alloy developed by SLM process along XY (45°) and Z (90°) orientations. These prepared samples were subjected to microstructural characterization by SEM and EDS. Mechanical properties like tensile and compression behaviours were evaluated according to ASTM standards. Findings: Microstructural studies revealed the effect of grains on the mechanical behaviour of Al-Mg10-Si alloy built in XY (45°) and Z (90°) orientations. EDS analysis confirmed the presence of Mg and Si elements in the Al matrix. Tensile strength of Al-Mg10-Si alloy built in XY (45°) orientation is 428.6 MPa against 408.3 MPa in Z (90°) orientations developed samples. Further, compression strength of samples developed in XY (45°) orientation is more than that of developed in Z (90°) orientations. Novelty: In the current study Al-Mg10-Si alloy samples were produced by selective laser meting method in XY (45°) and Z (90°) orientations. Very minimal investigations were carried out on Al-Mg10-Si alloy specimens built in XY (45°) orientation. Keywords: AlMg10Si Alloy; Microstructure; Tensile Behaviour; Compression Strength; Build Orientation
