A novel approach of fabricating monodispersed spherical MoSiBTiC particles for additive manufacturing

Abstract It is very challenging to fabricate spherical refractory material powders for additive manufacturing (AM) because of their high melting points and complex compositions. In this study, a novel technique, freeze-dry pulsated orifice ejection method (FD-POEM), was developed to fabricate spheri...
