测量了高强度钢中绝热剪切带的硬度，观察了绝热剪切带的微观组织形貌，研究了钢的碳当量和基体硬度对绝热剪切带组织和硬度特征的作用．结果表明：绝热剪切带易形成于高硬度钢中，但其硬度却与基体硬度无关，而仅取决于钢中的碳当量．绝热剪切带的硬度特征和带中细小、非变形组织形态等实验结果支持了高强度钢中绝热剪切带为相变带的观点．
Microstructure survey and hardness measurement were performed on the adiabatic shear band presented in high strength steels. The effects of carbon equivalent and hardness of matrix on microstructure and hardness features of adiabatic shear band were investigated. It was shown by the results that adiabatic shear band is inclined to form in high hardness steels, but its hardness is not influenced by the hardness of matrix, only depends on carbon equivalent of the steels. The white-etched adiabatic shear band presented in the steel can be named as transformed band because of its hardness characteristics and undeformed feature of microstructure.
