摘要
铅黄铜(HPb58-3)中添加微量稀土元素进行的研究表明,稀土元素具有细化晶粒、提高高温塑性和改善切削性能的功效。研制中还就稀土元素改善铅黄铜(HPb58-3)热加工性能的机理进行了初步的探讨。
Addition of a small ammount of rare earths in HPb58-3 has been investigated. The result shows that the addition of RE may increase the fineness of crystal particles, improve the hot working performance and the machinability. The mechanism of RE on the improvement of the hot working performance is also discussed preliminarily.
