چکیده انگلیسی
Selective laser melting (SLM) of Mg-Al powder mixture is a promising method to additively manufacture Mg-Al alloy components without using pre-alloyed powder as feedstock. However, the microstructure and consequent tensile properties of SLMed Mg-9â¯wt%Al powder mixture have not been systematically investigated. In this work, spherical Mg and Al powder with a weight ratio of 91:9 were mixed using ball milling and the mixture was SLMed at different processing parameters. Mg-Al alloy was successfully fabricated and the highest relative density achieved was 95.7%. The results of scanning electron microscopy showed that the microstructure and volume of defects could be controlled by tuning the processing parameters. The highest ultimate tensile strength achieved was 274â¯MPa, which was comparable to the strength of SLMed pre-alloyed Mg-9â¯wt%Al as reported in literature. Based on this study, SLM of different Mg powder mixture can be investigated in future.
