Abstract

It becomes possible in appropriate circumstances for similarly oriented plates of bainite or martensite to merge and form coarse crystallographically homogeneous domains whose presence leads to a deterioration in mechanical properties. A method is presented here for breaking up such domains, by introducing very small scale chemical composition variations in the austenite prior to its transformation.

Keywords: Bainite; Crystallographic grain size; Segregation; Intercritical annealing; Refinement
