... ( Ref 80 ) obtained densification to 7.52 g/cm 3 and passivation characteristics in 0.5 M H 2 SO 4 similar to wrought stainless steel. Transient liquid-phase sintering resulted in a single austenitic phase, eliminating potential mechanical property problems from secondary phases. The boron of the...
