预变形对Al-Cu-Mg-Ag合金时效组织及性能的影响
Effect of pre-deformation on aged microstructure and properties of Al-Cu-Mg-Ag alloy
摘要
Abstract
In order to analyze the influence of pre-deformation on the precipitated phase during the aging process of Al-Cu-Mg-Ag alloy,the diameter size and quantity density of the precipitated phase observed by TEM were quantitatively calculated by the Digital Micrograph software,and the results showed that the precipitated phase density of 20％pre-deformation aging alloy in-creased and that the diameter size decreased.In order to explore the influence of different pre-deformations on the mechanical properties of Al-Cu-Mg-Ag alloy in the aging state,the hardness of four deformation samples(0％,10％,20％,30％)was measured by the Vickers hardness tester at 185℃ aging 0～24h,and the results showed that the pre-deformation increased the hard-ness of the alloy,and that the peak hardness of the alloy was the highest(153HV)when the de-formation was 30％.In order to explore the influence of different pre-deformations on the corro-sion resistance of Al-Cu-Mg-Ag alloy in T6 state,the cyclic polarization curve test and intergran-ular corrosion experiment are carried out,and the results show that the best deformation pre-deformation(20％)of Al-Cu-Mg-Ag alloy makes the corrosion resistance the best.关键词
