Spheroidization in tool steels [PDF]
, 1970 A carbon steel, W1, and four other alloy tool steels, namely, A2, H13, D3, and M2, were spheroidized by five different procedures. Any modification made in the treatments for an individual steel were suggested by the results obtained with these five ...

Experiences in powder plasma spheroidization
, 2018 Plasma spheroidization is a method by which originally non-spherical or at least not optimally round powder particles are melted with plasma flame. Natural spheroidization occurs due to surface tension, which leads to better flowing powders used for ...
