摘　　要：对Al－B或Ti-B处理的1．25Cr－0．5Mo钢的研究结果表明：（1）Al-B和Ti－B处理明显地增加了1．25Cr－0．5Mo的淬透性．强度及塑、韧性；（2）Al－B和Ti－B处理均使1．25Cr－0．5Mo钢的抗氢性能明显提高。当B含量相当时．Ti－B处理钢的抗氢蚀性能优于Al-B处理钢；（3）B含量较高时．钢的抗氢蚀性能较强，但塑、韧性及回火性能却相对较差。因此，较低含量B处理更有利于材料综合性能的改善。The research results of steel 1. 25Cr-0. 5Mo treated with Al-B/Ti-B show that (a ) with treatedby Al-B/Ti-B, the hardenability, strength, ductility and toughness of steel increase obviously: (b) the hydrogen attack resistance of steel 1. 25Cr-0. 5Mo improves after Al-B or Ti-B treating. and the hydrogen attack resistance of Ti-B treated steel is better than that of Al-B treated steel where the B content is equivalent; (c )The lower B content is beneficial to the improvement of the comprehensive performance and properties of steel1. 25Cr-0. 5Mo.
