Mar 01,1978·The alloying elements segregate to the interdendrltic areas and form MC carbides.Since the cobalt-base alloy Mar M-509 has a fcc cobalt matrix,the loss of segregation of solutes such as Ta,C and Ni (fcc stabilizers) from the dendrite arm areas leads to the formation of stacking faults (local regions of hcp structure).
