摘要
影响冷镦钢质量的主要因素之一是顶锻开裂。结合3年来的生产实践,把顶锻开裂的形式归纳成两部分,即内部塑性型开裂和表面裂纹源型开裂。同时,介绍了裂纹的表现形式,对其产生机理和断裂力学理论进行了分析研究,提出了生产中的针对措施。
One of the main factors affecting the quality of cold-forging steel is the upset forging cracking. Combined with the 3a practice, the upset forging cracking is divided into two kinds, internal plastic-type cracking and surface cracking. This paper introduced the forms of cracks, analyzed the mechanism and the theory of fracture mechanics as well as countermeasures.
