摘　　要：介绍了Ｂｉ－Ｍｎ（及Ｂｉ－Ｍｎ－Ｆｅ）系和Ｂｉ－Ｎｉ（Ｂｉ－Ｎｉ－Ｆｅ）系高熔点铋中间合金的相及显微组织特征，以进一步建立含铋相的性质、数量与合金熔点间的定量关系。本文为Ｂｉ－Ｍｎ系、Ｂｉ－Ｎｉ系中间合金成份的优化提供了依据。The characteristics of the phases and microstructures in the Bi master alloys including binary Bi-Mn and Bi-Ni as well as pseudo-ternary Bi-Mn-Fe and Bi-Ni-Fe are intreduced in this paper.hese master alloys gain a higher 'melting temperature' . It is indicated that the performances of the Bi bearing phase and its quantity relates to the 'Melting temperature' of the master alloy. Based on the results of this in-vestigation,it ls possible to optimize the composition of the master alloys.

关 键 词：Bi-Mn系 Bi-Ni系 不锈钢 混冲法 铋基合金
