摘要：

It was found that remelting is the origin of grain refinement in undercooled Cu30Ni70 specimens. It was also demonstrated that composition difference across a dendrite is the cause of remelting. The critical undercooling, Delta T* for grain refinement is 145 K for undercooledCu(30)Ni(70). (C) 1995 American Institute of Physics.
