该数据集主要对马鞍山钢铁股份有限公司生产的抗震耐蚀耐火热轧H型钢在进行高温回火后进行力学性能拉伸后的断口形貌观察,通过对断口形貌观察,研究该回火工艺下材料拉伸性能的变化规律。
The data set mainly observed the fracture morphology of seismic corrosion-resistant and fire-resistant hot rolled H-beam produced by Maanshan Iron and Steel Co., LTD. After tempering at high temperature and stretching mechanical properties, the variation law of material tensile properties under the tempering process was studied by observing the fracture morphology.
