摘　　要：用硬度和拉伸试验及其数据的统计分析研究了塑性变形诱发内生复合板(DISC)的强度随冷轧形变率的变化规律。结果表明马氏体相变强化、时效强化、加工硬化和动态应变时效强化的叠加是使DISC板具有超高强度的主要原因。The correlation between cold-rolled reduction and yield strength of the deformation induced in-situ composite (DISC) plates produced from Cr-Mo-V steel by appropriate pretreatment and cold-rolling was studied by using hardness tests, tensile tests and statistical analysis of these experimental data. The results indicate that the strengthening mechanisms of the DISC plates are solid solution, martensitic transformation, precipitation, work-hardering and dynamic strain aging, and the ultra-high strength of the DISC plates can be described by the superposition of these individual strengthening effect.
