... high temperatures. Thus cavity nucleation and growth are retarded, and ductility is high. The evolution of microstructure in high-SFE (and some low-SFE) materials worked at lower temperatures, such as those characteristic of cold-working, is similar. At these temperatures, subgrains may also form and...
