Zusammenfassung:The invention discloses an austenitic stainless steel heat treatment state rapid detection method and belongs to the technical field of metal material detection for special equipment. According to the method, hardness measurement and ultrasonic detection are carried out on the workpiece, measured data are calculated and processed to obtain a Leeb hardness dispersion coefficient, a material attenuation coefficient, a wavelet packet frequency domain main peak energy index and a wavelet packet time domain main peak energy index, a comprehensive index is constructed, and the material state of the workpiece is evaluated through the comprehensive index. The heat treatment state of the austenitic stainless steel can be quickly inspected. 一种奥氏体不锈钢热处理状态快速检验方法,属于特种设备用金属材料检测技术领域。本发明通过对工件进行硬度测量和超声检测,将测得的数据计算处理获得里氏硬度分散系数、材质衰减系数、小波包频域主峰能量指标和小波包时域主峰能量指标,并构建综合指标,通过综合指标来评价工件的材质状态,以实现奥氏体不锈钢热处理状态的快速检验。
