Abstract

Beam bending analysis is used to evaluate the viscosity of boron doped water atomized 316L powder compacts during sintering process. The viscosity of the beam decreases with an increase in sinter temperature. Upon liquid formation the compact becomes soft. The effective viscosity of water atomized 316L with 0.2 wt. % boron at the onset of densification is ~250 MPa.s.
