中文摘要：通过向H08钢中添加微量的铈锡，研究了不同铈含量对含锡钢性能的影响。实验结果表明，随着铈含量的增加，含锡钢在高温下晶粒的长大趋势越来越慢，而强度和韧性也随着提高；同时发现，铈改善了含锡钢的断裂机制。
英文摘要：Adding a bit of cerium and tin to H08 steel, the effects of cerium content on mechanical properties of the steel containing tin were studied. The results show that the growth of grain at high temperature becomes slow with the increase of cerium content, but intensity and tenacity enhance; at the same time, cerium improves the cracking mechanism of the steel containing tin.
