摘要
总结了有关条状马氏体形态对钢力学性质(主要为强度)影响的文献。由于马氏体束比领域小很多,且也具有高角度位向差界面,一般束宽为决定条状马氏体强韧性的主要因素。但当马氏体条宽在几十nm级时,条宽将对钢的强度和韧性作更大贡献。
Literatures concerning effect of morphology of lath martensite on the mechanical properties （mainly the strength） of steel are reviewed. Since the martensite block size is much smaller than the packet size and also possesses boundary with high angle misorientation, the block width in general dominates the strength and toughness of lath martensite. However, when the lath width is in nanoscale, it should make greater contribution to the strength and toughness of steel.
