该数据集主要对马鞍山钢铁股份有限公司生产的99mm翼缘厚度规格热轧H型钢进行维氏硬度检测,采用HV0.5硬度压力进行硬度试验,通过材料硬度反应材料强度的对应关系,同时为后续焊接热影响区的组织硬度变化提供对比参考。
The data set mainly tested vickers hardness of 99mm flange thickness hot-rolled H-beam produced by Maanshan Iron and Steel Co., LTD. Hardness test was carried out by HV0.5 hardness pressure, and the corresponding relationship of material strength was reflected by material hardness. At the same time, it provided a comparative reference for the change of microstructure hardness in the heat affected zone of subsequent welding.
