摘要：
The solidification behavior of Nd-Fe-B undercooled melts with the stoichiometric composition of Nd,Fe,,B was studied. The melts experienced a large undercooling of 180 K during static furnace cooling. The resultant alloy ingots consisted of fragmented dendritic iron phase together with the Nd,Fe,,B phase. However, quenching the undercooled melts at various undercooling levels significantly changed the resultant microstructures. Nd-Fe-B alloy ingots with columnar Nd2Fe14B phase were obtained by quenching the melts with an undercooling of 50 K. (C) 2001 Elsevier Science B.V. All rights reserved.
