Mitigation of lack of fusion defects in powder bed fusion additive manufacturing (2018, background): “Slower scanning speed was also found to reduce lack of fusion defect for titanium alloys [4,6,7,12,13] and aluminum alloys [8–10].”
Effects of hot isostatic pressing on the elastic modulus and tensile properties of 316L parts made by powder bed laser fusion (2017, background): “15 welding and more recently in powder bed laser fusion [46], [56], [57]– when temperatures in the melt-pool rise above the vaporisation temperature of the various alloy components and a plasma is formed, enhancing laser absorption.”
