Interesting effects on the microstructural evolution and dynamic tensile deformation behavior of aluminum alloys AA6082 and AA7075 are revealed by investigating the influence of cooling rates within a novel thermo‐mechanical process. Dynamic tensile tests at strain rates of 40 to 400 s⁻¹ coupled with digital image correlation show an increase in yield strength, ultimate tensile strength, but also in elongation to failure with increasing strain rate. Further details can be found in the article number 2000193 by Emad Scharifi and co‐workers.

根据新的热机械处理策略加工的高强度铝合金的动态拉伸变形

通过研究新型热机械过程中冷却速率的影响，揭示了对铝合金AA6082和AA7075的微观组织演变和动态拉伸变形行为的有趣影响。在40至400 s ^-1的应变速率下进行的动态拉伸试验与数字图像相关性表明，屈服强度，极限抗拉强度均有所提高，但随着应变速率的提高，断裂伸长率也有所提高。可以在Emad Scharifi及其同事的文章编号2000193中找到更多详细信息。
