摘要
在Ｚ２５、Ｚ３０合金中添加稀土元素，研制成ＺＲ２５、ＺＲ３０新型矿用合金，使其抗弯强度、冲击韧性提高１０％以上，使用寿命大为增加。并在进行对比试验的基础上，简要讨论和分析了稀土元素在矿用合金中的作用。
New mining carbides ZRZo and ZR30 are developed by addictrare earths into 225 and 230.The bending strength and impact toughness-of the new alloys have been increased over 10adO with much longer servicelife.This paper has briefly discussed and analyzed the functioll of rareearth elements in mining carbides on the basis of comparative test.
