摘要

本文采用光镜、电子显微镜、X射线衍射仪、X射线应力分析仪及测定机械性能的方法对工业锻铝合金LD

的固溶处理、时效和稳定化处理对组织、性能、应力及尺寸稳定性的影响进行了试验研究。研究认为在获得较好综合机械性能的情况下

控制固溶化条件、淬火介质温度、时效温度及时间和冷热循环稳定化处理条件

可以稳定组织

减少残余应力

满足尺寸稳定性的要求。从而提出了适合于精密机械与仪器中高尺寸稳定性的零件的最佳工艺规程

Abstract

This paper deals with the influence of solution treatment

ageing and stabilizing process on the structures

propertles

stresses and dimensional stability of conmercial forging aluminium LD

by means of metalloscope

electron mic roscope

x-ray diffractometer

x-ray stress analyzer and method for the determination of mechanical properties. The experimental results suggested that under certain circumstances a good strengthening and toughenning effect can be obtained. By controling the conditions of solution treatment

quenching tempereture

ageing tempereture

ageing time and conditions of cold-heat cyclic stabilizing it may stabilize structures

reduce the residual stresses and meet the need of dimensional stability of parts required high dimensional stability in fine machine and fine instrument.
