Abstract: | Because Cu is an austenite gamma stabilizer, it is thought that Cu only dissolves in the FCC gamma phase but not in the BCC delta when Cu-containing PHSS are treated in a dual delta-gamma solid solution at high temperature. However, the nano precipitation of Cu in the allotriomorphic delta found upon quenching from 1295 degrees C. To study this unexpected phenomenon, thermodynamic calculations wer... |
