0 前言 弹簧是重要的通用性基础零件,基本功能是利用材料的弹性和弹簧的结构特点,在产生变形和恢复时,机械能或动能与形变能产生转换。影响弹簧质量的因素是多方面的,其中材料及热处理对弹簧的性能及寿命有着重要的影响。
0 Introduction Spring is an important universal basic part. The basic function is to make use of the elasticity of the material and the structural characteristics of the spring. When the deformation and recovery occur, the mechanical energy or kinetic energy and deformation can be converted. The factors that affect the quality of the spring are many and varied, and the material and the heat treatment have an important influence on the performance and life of the spring.
