摘　　要：本文研究不同硼含量对12CrNi3MoV钢力学性能的影响及其作用机制。如酸溶硼含量B_(sol)<0.001％时,钢的韧性有所改善;而B_(sol)>0.001％时,钢的韧性随硼含量的增加而逐渐下降,这是由于Fe_(23)(CB)_6等碳硼化物的析出而引起的。The influence of various boron contents on the properties of 12CrNi3MoV steel and its me-chanism were studied. When soluble boron (B_(sol)) is less than 0.001%, toughness of the steel isimproved in some extent. However, when B_(sol) is more than 0.001% toughness of the steel dec-reases gradually as the B_(sol) increases. The decrease of toughness is a consequence of precipi-tation of boron carbides such as Fe_(23)(CB)_6.
