Plasma Spheroidisation of Irregular Ti6Al4V Powder for Powder Bed Fusion

Metal powders suitable for use in powder bed additive manufacturing processes should ideally be spherical, dense, chemically pure and of a specified particle size distribution. Ti6Al4V is commonly used in the aerospace, medical and automotive industries due to its high strength-to-weight ratio and e...
