Abstract

Abstract: M2052 manganese-copper powder was prepared by vacuum induction melting gas atomization (VIGA), and the alloy specimen was directly formed by the selective laser melting (SLM) method. Processed by solid solution and aging treatments and hot isostatic pressing, the manganese-copper alloy prepared by SLM method was studied by thermodynamic calculation, microstructure analysis and mechanical property tests. The results show that the tensile strength and yield strength of the manganese-copper alloy prepared by the SLM method are higher, but the impact absorbed energy is low and the plasticity is poor. After hot isostatic pressing, the comprehensive mechanical properties of the alloy are significantly improved.

Key words: selective laser melting, hot isostatic pressing, M2052 alloy, microstructure
