摘要
文中研究了温变形工艺中变形温度和变形程度对5A06铝合金显微组织的影响.结果表明：变形温度低于470℃、变形量在45%～50%范围时,随变形温度的升高,组织内第二相数量越少,基体晶粒越大;变形温度高于470℃时,发生再结晶.当变形温度控制在350℃,变形量小于70%时,随变形量增大,晶粒被细化,且第二相呈弥散分布;超过70%,也将发生再结晶.
The article has studied effect of the forming temperature and forming degree on the microstructure of antirust aluminium alloy 5A06. Results of the study show： when forming temperature is under 470℃ and deformation degree is within 45 % -50 96 % deformation temperature rise accompany the number of the second particles decreasing and the crystal grain growing up,Upward 470℃ ,working a recrystallization . When forming temperature is 350℃ and deformation degree is less than 70% .deformation degree rise accompany the crystal grain minishing upward 70% ,working a recrystallization.
