摘　　要：钛合金铸件冶金缺陷线性荧光显示定性困难,影响产品质量判定结论。为提高判定准确率,采集了50件钛合金铸件冶金缺陷线性荧光显示样本,分析了钛合金铸件冶金缺陷线性荧光显示形貌特点与实际缺陷性质的对应关系,找出了裂纹、冷隔、线性疏松和线性夹杂类缺陷荧光显示的典型特征。通过开展擦拭技术试验,总结了线性缺陷荧光显示擦拭后形貌的动态显示特征,形成钛合金铸件冶金缺陷线性荧光显示动态定性的方法,为准确判定裂纹、冷隔、线性疏松和线性夹杂等缺陷提供依据。The qualitative difficulty of linear fluorescence display of metallurgical defects in titanium alloy castings affects the product quality judgment.In order to improve the accuracy of determination,50 samples of titanium alloy castings were collected for linear fluorescence display of metallurgical defects.The corresponding relationship between the characteristics of linear fluorescence display of metallurgical defects of titanium alloy castings and actual defect properties was analyzed,and the typical characteristics of fluorescence display of cracks,cold shuts,linear porosity and linear inclusions were found out.In this paper,the dynamic display characteristics of linear defects by fluorescent display after wiping were summarized through the test of wiping technology,and the method of forming the dynamic qualitative method of linear fluorescence display of metallurgical defects in titanium alloy castings was developed,which provided the basis for the accurate determination of cracks,cold shuts,linear porosity and linear inclusions defects.
