Journal ArticleDOI
Transformation of austenite to duplex austenite-ferrite assembly in annealed stainless steel 316L consolidated by laser melting
TL;DR: In this article, the phase changes in heat treated samples were characterized using X-ray diffraction (XRD) and electron back scattering diffraction(EBSD) using a focused Nd:YAG laser beam.
Journal ArticleDOI
Defects-tolerant Co-Cr-Mo dental alloys prepared by selective laser melting.
TL;DR: Although the formation of microstructural defects is hard to be avoided during the SLM process, theSLM CoCrMo alloys can achieve improved mechanical properties than their casted counterparts, implying they are "defect-tolerant".
Journal ArticleDOI
Austenitic stainless steel strengthened by the in situ formation of oxide nanoinclusions
TL;DR: In this article, an austenitic stainless steel was prepared by laser melting and high resolution transmission electron microscopy with energy dispersive spectrometry confirmed the in situ formation of oxide nanoinclusions with average size less than 50 nm.
Journal ArticleDOI
Thermal expansion and glass transition temperature of the rare-earth doped oxynitride glasses
TL;DR: In this paper, the effects of rare-earth elements and nitrogen on the properties of bulk glasses were investigated to separate the effect of rare earth elements and rare earth dopants on bulk glasses.
Journal ArticleDOI
