摘要：

The controlled solidification of a metal from an undercooled melt into a predetermined metastable product phase has been demonstrated for the iron-nickel alloy system. This was achieved by introducing an external nucleation seed of suitable catalytic potency. The metastable b.c.c. phase was identified through its melting point well below the equilibrium f.c.c. value, in agreement with a calculated metastable phase diagram. © 1990 IOP Publishing Ltd.
