Discontinuous coarsening of discontinuous precipitates in a Co–6 at.% Mo alloy

The morphology and growth kinetics of the discontinuous coarsening of discontinuous precipitates in a Co–6 at.% Mo alloy have been investigated at temperatures ranging from 773 to 998 K by optical and scanning electron microscopy and X-ray diffraction. At all aging temperatures the alloy was observed to decompose completely by discontinuous precipitation into a fine lamellar structure of b.c.t. Co rich solid solution and an intermetallic...
