研究了经低温轧制和温轧制加工的 5052 A]合金的显微组织演变和相应的机械性能。深冷轧制与 448 K 温轧制相结合的应用表明，抗拉强度显着提高，高达 452 MPa。使用差示扫描量热计和透射电子显微镜研究了温轧过程中发生的动力学和微观结构演变。抗拉强度的显着提高是通过温轧过程中细小析出物的形成实现的。研究发现，深冷轧制与温轧制相结合可有效提高机械性能。 [doi:10.2320/matertrans.MD200801]
The microstructural evolution and the corresponding mechanical properties of a 5052 A] alloy processed by cryogenic rolling followed by warm rolling were investigated. The application of cryogenic rolling combined with warm rolling at 448 K showed a significant improvement of tensile strength up to 452 MPa. The kinetics and the microstructural evolution occurred during warm rolling were investigated using differential scanning calorimeter and transmission electron microscope. This notable increase of tensile strength was achieved by the formation of fine precipitates during warm rolling. It was found that the cryogenic rolling combined with warm rolling would be effective in improving mechanical properties. [doi:10.2320/matertrans.MD200801]
