| 摘 要： | 研究了退火工艺对3003铝合金板微观组织与力学性能的影响。试验结果表明,3003铝合金板退火后第二相粒子主要为Al6(Mn, Fe)、Al6Mn以及在位错或者亚晶界等缺陷处形成的α-Al(Fe, Mn)Si相。随退火温度升高和保温时间延长,第二相粒子发生粗化,并出现了少量的弥散第二相。当退火温度为450 ℃时,第二相又重新固溶到基体。随退火温度升高,3003铝合金板硬度稳定在31.0 HV0.5 左右,抗拉强度整体上呈下降趋势,伸长率呈增加趋势。

| Abstract: | Effect of annealing process on microstructure and mechanical properties of the 3003 aluminum alloy plate was studied. The results show that the annealed second phase particles is mainly composed of Al6(Mn, Fe), Al6Mn and α-Al(Fe, Mn)Si phases formed at defects such as dislocations or subgrain boundaries. With the annealing temperature and holding time increasing, the second phase particles coarsen and grow, and a small number of dispersed second phases appear. When the annealing temperature is 450 ℃, the precipitated phase starts to re-dissolve into the matrix. With the annealing temperature increasing, the hardness is stabilized at about 31.0 HV0.5, and the tensile strength tends to decrease as a whole, while the elongation increases. |
