Journal ArticleDOI
Microstructure and mechanical properties of pure copper manufactured by selective laser melting
TL;DR: In this article, the influence of laser linear energy density on the microstructures and mechanical properties of the SLM copper samples were investigated theoretically and experimentally, and it was shown that nearly full dense copper with desirable mechanical properties can be fabricated through SLM.
Journal ArticleDOI
Study of the microstructure and mechanical performance of C-X stainless steel processed by selective laser melting (SLM)
Xingchen Yan,Xingchen Yan,Chaoyue Chen,Cheng Chang,Dongdong Dong,Ruixin Zhao,Richard Jenkins,Jiang Wang,Zhongming Ren,Min Liu,Hanlin Liao,Rocco Lupoi,Shuo Yin +12 more
TL;DR: In this paper, a new precipitation hardening stainless steel (PHSS), C-X stainless steel, was manufactured using selective laser melting (SLM) technology, and a series of heat treatments were applied to improve the mechanical properties of the as-built samples.
Journal ArticleDOI
Selective laser melting (SLM) of CX stainless steel: Theoretical calculation, process optimization and strengthening mechanism
Dongdong Dong,Cheng Chang,Cheng Chang,Hao Wang,Xingchen Yan,Xingchen Yan,Wenyou Ma,Min Liu,Sihao Deng,Julien Gardan,Julien Gardan,Rodolphe Bolot,Hanlin Liao +12 more
TL;DR: In this paper, the effect of laser linear energy density on the microstructure characteristics, phase distribution, crystallographic orientation and mechanical properties of these CX stainless steel samples were investigated theoretically and experimentally via scanning electron microscopy, X-ray diffraction, electron backscatter diffraction (EBSD), and transmission electron microscope (TEM).
Journal ArticleDOI
Effect of building directions on the surface roughness, microstructure, and tribological properties of selective laser melted Inconel 625
