摘要
通过对热轧中厚板在不同深度上进行布氏硬度的测定 ,表明测量深度对硬度的明显的影响 ,并指出获得稳定值的必要性。金相观察证实了表面脱碳层的存在是产生硬度值不稳定的原因。
The Brinell hardness number of the hot rolled plates varies with measurement on the different batch of the products. Measurements on the plates in different depth demonstrates that the measuring depth affects the Brinell hardness number and metallographic examination reveals that existence of a decarbonization layer is the main cause for the variation of the Brinell hardness number.
