| 摘 要： | 测量了中碳Cr-Ni-Mo-V系低合金超高强度钢中绝热剪切带(ASB)及其周围金属的显微硬度,观察了其微观组织。结果表明:绝热剪切带的硬度远高于基体的硬度,达700～830HV0.05,为多孔状的非晶组织;紧靠ASB的是窄的过渡带,为重新生成的细小的马氏体组织;外层则是宽约20μm的软化带,为较高温度下的回火马氏体组织,其硬度低于基体。

| Abstract: | Microstructure and microhardness of adiabatic shear band(ASB) and those near ASB in medium carbon Cr-Ni-Mo-V ultra-high strength low alloy steel plate have been investigated.The results show that microhardness of ASB can reach 700～830HV0.2,which is much higher than that of matrix.The microstructure of ASB is amorphous and porous.A narrow transitional band surrounds ASB and its microstructure is fine re-transformed martensite.Microstructure of a soft band(about 20 μm width) outside ASB is high temperature tempered martensite,whose microhardness is lower than that of matrix. |
