Selective laser melting (SLM) has been proved to be a promising additive manufacturing technique for production of high-performance metal matrix composites (MMCs) with unique microstructures. In this study, the SiC- reinforced 316L MMCs were prepared by SLM and effects SiC addition on densification, microstructure evolution, mechanical properties tribological behavior systematically investigated. The SiC/316L fabricated close full density high relative over than 99.7%. grains significantly...
In this work, 316L stainless steel samples were prepared by selective laser melting (SLM) and the effects of bulk energy density on resulting mechanical properties evaluated. The results show that SLM first improved then deteriorated with increasing density. When was 70.2 J/mm 3 , obtained tensile strength yield vertical to building direction 720 546 MPa, respectively, which surpass design requirements for forged steel. influence microstructure is also discussed. purpose research provide...
The objective of this study was to investigate the effects different Cr content on microstructure, mechanical properties, and corrosion resistance powder metallurgy ferritic stainless steels (PM FSSs). PM FSSs were prepared by compacting pre-alloyed powders with ranging from 17 wt.% - 26 at 600, 700, 800 MPa, then sintered in hydrogen protective atmosphere 1380℃ for 2 hours. results showed that porosity decreased increasing compaction pressure, hardness increased pressure content. yield...
