裂纹是在锻造和热处理生产过程中常见的缺陷之一,通过对裂纹产品试样进行收集、分析、整理,可将裂纹大致分为三类:锻造裂纹、折叠和淬火裂纹。通过晶相实验分析,可获得三种类型裂纹的形成原因,有针对性的提出减少裂纹产生的建议性措施,从而提高产品的质量和性能。 Crack is one of the common defects in the process of forging and heat treatment. By collecting, analyzing and sorting the cracked samples, the cracks can be divided into three categories: forging, folding and quenching. Through the crystal phase experimental analysis, the reason for the formation of three types of cracks can be obtained, and the proposed measures to reduce the occurrence of cracks are proposed in a targeted manner so as to improve the quality and performance of the product.
