摘要： The present invention relates to the field of metallurgy, more particularly non-ferrous alloys. The first aspect of the present invention relates in particular to titanium (Ti) alloys suitable to be manufactured by a method of additive manufacturing such as laser powder bed fusion. The titanium alloy, according to the present invention, comprises titanium and further metallic elements, wherein titanium form microstructural titanium alloy matrix. The further metallic elements are homogenously dispersed in the titanium alloy matrix. The alloy microstructure, when the alloy is subjected to mechanical loading, changes its microstructure from an initial state to a final state through a martensitic transformation or a mechanical twinning. The initial state comprises a plurality of defects and a plurality of porosities, wherein the plurality of defects and said plurality of porosities represent between 1% and 6% in volume of the alloy; and wherein strength-ductility balance the final state is lower than 15% compared to the initial state. The second aspect of the present invention relates to a powder made of the titanium alloy according to the first aspect of the present invention. The third aspect of the present invention relates to a method of manufacturing the titanium (Ti) alloys.

摘要： Methodologies, systems, and devices are provided for producing metal spheroidal powder products. Dehydrogenated and spheroidized particles are prepared using a process including introducing a metal hydride feed material into a plasma torch. The metal hydride feed material is melted within a plasma in order to dehydrogenate and spheroidize the materials, forming dehydrogenated and spheroidized particles. The dehydrogenated and spheroidized particles are then exposed to an inert gas and cooled in order to solidify the particles into dehydrogenated and spheroidized particles. The particles are cooled within a chamber having an inert gas.
