一、序言所谓热处理一般是包括非常广泛范围的操作,例如:在金属手册里从热处理术语解说来看,热处理是“为了对固体金属或合金给予所要求的特性所进行的加热操作和冷却操作,而为了热加工的加热除外”。然而铝合金的热处理一般则意味着固溶热处理、淬火及时效硬化处理的周期,按照这种操作是否存在有效性,而把合金分为可热处理合金 I. Preface The so-called heat treatment generally includes a very wide range of operations, for example: in the metal manual from the heat treatment terminology commentary, heat treatment is "for the solid metal or alloy to give the required characteristics of the heating operation and cooling operation, In addition to the heat of heating except. However, aluminum alloy heat treatment generally means that the solution heat treatment, hardening and aging hardening cycle, according to whether there is any validity of this operation, and the alloy is divided into heat-treatable alloy
