在对于机械零件的失效原因进行科学的分析,找出它的薄弱环节之后,我们就可以从结构设计、材质、热处理和冷、热形变强化等方面采取措施,提高零件质量,使它既轻巧,又耐用。必须重视热处理和形变强化在提高零件强度中的作用。热处理强化和形变强化使用得当,常常是事半功倍,达到多、快、好、省的效果。当然这一切,都必须基于对零件失效规律的深入了解,即在材料强度科学理论指导下,方能顺利进行。现将目前行之有效,并在国内取得一定成果的热处理及形变强化方法择要简单介绍如下:
After a scientific analysis of the causes of failure of mechanical parts to find out its weak links, we can take measures to improve the quality of the parts from the structural design, material, heat treatment and cold and heat deformation to make it lightweight, And durable. Must pay attention to heat treatment and deformation strengthening in improving the role of parts strength. Heat treatment and deformation strengthening and use properly, often with less effort, to achieve more, faster, better, the province’s effect. Of course, all this must be based on the in-depth understanding of the law of failure of parts, that is, under the guidance of the material strength of scientific theory, can successfully proceed. At present, the most effective methods of heat treatment and deformation enhancement that have achieved some success in China are as follows:
