θ″相试样和含θ′相试样在变形的过程中发生了明显的析出相回溶有关.说明强变形诱导析出相回溶现象在保证强度得到提高的同时,缓解加工硬化引起的脆性,改善塑性. 关键词:Al-Cu合金;强塑性变形;析出相回溶;力学性能 中图分类号:TG146.2 文献标志码:A Effect of re-dissolution of severely... values of specimens containing θ″ and θ′ phases show an ephemeral decrease, which overall increase after MAC. These two unusual phenomena can be ascribed to the profound re-dissolution of θ" and θ......
Trans. Nonferrous Met. Soc. China 29(2019) 2455-2462 Re-dissolution and re-precipitation behavior of nano-precipitated phase in Al-Cu-Mg alloy subjected to rapid cold stamping Cai-he FAN1, Ling OU1...) and hardness test were used to study the re-dissolution and re-precipitation behavior of nano-precipitates of the spray-formed fine-grained Al-Cu-Mg alloy during rapid cold stamping deformation. Results......
文献标志码:A 文章编号:1672-7207(2010)05-1782-09 Re-ageing behavior of Al-Cu alloy after re-dissolution...: Supersaturated solid solution was formed after re-dissolution of precipitated phases during multi-axial compression in aged Al-Cu alloy. The re-ageing behavior of strain-induced supersaturated solid solution......
of hardness are related to the mechanism of re-dissolution of precipitates. A critical nuclei size concept is provided to express the mechanism of such re-dissolution of three precipitates in Al-Cu alloys. Key words: Al-Cu alloy; re-dissolution; ECAP; precipitated phase  ......
of about 200 nm and a width of about 100 nm than the latter in equiaxed shape with a diameter of about 600 nm. Also, at room temperature grain refinement is suppressed by the re-dissolution of severely deformed precipitated phase, which is helpful to the decrease of dislocation density, and at 50 ℃ the re-dissolution and re-precipitation of precipitate phase contributes to the grain refinement......
