... deformations, stresses are necessary that can have different causes. During heat treatment, primarily a superposition of transformation and thermal stresses exists. They arise from thermal gradients and gradients in the chemical composition, some of which may be residual from the segregation that occurs during...

... chemical composition, heat treatment, and cooling. The carbides also may be different sizes and somewhat varying shapes, even for the same phase. In Co-Cr-C, M 7 C 3 and M 23 C 6 are common. In the as-cast condition, the MC phase is predominant, because it is the first formed on cooling from the molten...
