Controlled phase selection has been demonstrated in the crystallization of a melt from deep undercooling. In the Fe-Ni alloy system the metastable b.c.c, phase has been solidified by a seeding technique for nickel content up to 30%, using a trigger made of FeMo alloy. The stable f.c.c, phase is show
Fluxing of 1-5 mm diameter droplets of molten Fe40Ni40B20 permits high undercoolings to be achieved prior to solidification onset. A series of microstructures increasingly far from equilibrium is found as the undercooling is increased. Modification of dendrite and eutectic morphology, and metastable
