| 摘 要： | 研究了镧的加入对锌阳极带韧脆转变温度的影响,并对其金相组织进行了观察.结果表明,适量镧对于改善锌阳极带的综合性能具有重要作用.同不含镧的锌带相比,加入0.1%镧的锌带的韧脆转变温度变化不大,加入0.3%镧的锌带的韧脆转变温度降低明显.添加适量镧后,锌阳极带组织性能也发生了变化.晶粒度从原来的6.5～7级变为8～9级左右.适量镧可以细化晶粒,改善内部组织,提高锌阳极带的综合性能. |

| Abstract: | The effect of lanthanum on low temperature brittleness of zinc anode ribbon was studied and its metallograph was observed. The experiment results show that adding suitable content of La can reducegrain size and temperature of brittleness of zinc anode ribbon. Therefore, suitable addition of lanthanum is very significant to improve its comprehensire properties. |
| Keywords: | metal materials zinc anodes ribbon low temperature brittleness grain fining rare earths |
