摘要：
Metastable materials produced from deeply undercooled melts can provide some interesting materials properties. This review surveys recent studies of rapid and/or undercooled solidification in Fe-Ni or Fe-Cr-Ni steels and Ti-Al alloys. The effects of compositions and processes on the formation of metastable phases are discussed in terms of thermodynamic stability and the kinetics of nucleation and growth. In addition, a new approach by nucleation control is proposed to produce metastable materials. (C) 1997 Elsevier Science S.A.
