5.4.6精密热处理1)基本概念。精密热处理是采用先进的工艺、设备与检测体系精密控制相变的热处理。其主要内涵包括精密组织、精密残余应力场、精密表面和精密轮廓尺寸。传统热处理对组织、表面和轮廓尺寸给予了较大的关注,但残余应力场却关注甚少。精密热处理的目标是赋予材料和关键构件 5.4.6 Precision Heat Treatment 1) Basic Concepts. Precision heat treatment is the use of advanced technology, equipment and testing system precision control of the phase change heat treatment. Its main connotation includes precision organization, precise residual stress field, precision surface and precise contour size. Traditional heat treatment has given more attention to the organization, surface and outline size, but the residual stress field has paid little attention. The goal of precision heat treatment is to give materials and key components
