冶金因素影响绝热剪切带形成的金相观察
Effects of Metallurgical Factors on the Forming of Adiabatic Shear Band
【摘要】 对在相同爆炸复合条件下几种不同状态的金属所产生的绝热剪切带(ASB)的显微组织进行了观察及显微硬度测定,探讨了不同的相组成、预变形程度和晶体结构对绝热剪切带形成的影响。结果表明:ASB的形态、大小和数量受材料的预冷变形程度、成分、晶体结构、相组成等因素的影响;ASB的硬度值均高于基体。
【Abstract】 This work investigated the effects o f the metallurgical parameters on th e forming of adiabatic shear bands(ASBs )in some different state metals under the same explosiv e cladding process by observing microstructures and measuring microhardness.The results indicated that the shape,size and quantity of ASBs a re affected by the factors of pre-deformed degree,crystal structure,ph ase states etc.The mi-cro-hardness of ASB is higher than th at of the matrix.
