Powder feedstock is a major cost driver in metal additive manufacturing (AM). Replacing the
spherical powder with the cost-efficient non-spherical one can reduce the feedstock cost up …

This study investigates the use of hydride-dehydride non-spherical Ti-6Al-4V powders in
laser powder bed fusion process and the effects of post-heat-treatments on additively …

High-strength steels are mainly composed of medium-or low-temperature microstructures,
such as bainite or martensite, with coherent transformation characteristics. This type of …

Abstract Laser-welded Ti-6Al-4 V is prone to severe residual stresses, microstructural
variation, and structural defects which are known detrimental to the mechanical properties of …

This study investigates the multifaceted interdependencies among powder characteristics
(ie, non-spherical morphology and particle size ranging 50–120 or 75–175 µm), laser …

Although variant selection during the phase transformation of zirconium (Zr) alloys has been
studied extensively, studies on the formation mechanism of microstructural characteristics …

In this study, corrosion-erosion performances of Ti-6.5 Al-2Zr-1Mo-1V fabricated using two
different feedstocks namely gas-atomized (GA) spherical powder and modified hydride …

The process of employing laser powder bed fusion (L-PBF) process to refractory materials,
such as chromium (Cr), remains challenging because of its high ductile-brittle transition …

中文摘要高强度钢主要由具有协变相变特征的贝氏体或马氏体等中低温相变组织构成.
