Abstract
The mechanical behaviour of powder metallurgy products is conditioned not only by the presence of non-metallic inclusions, which can act as crack initiation sites, but also by the degree of structural and chemical homogeneity. In particular, segregation and precipitation at prior particle boundaries (p.p.b.’s) can lead to decohesions when the HIPed material is deformed, especially during creep and fatigue testing.
