In present investigation, an effective thermomechanical treatment (TMT) was developed to improve the mechanical properties of rolled 1100/7075 Al alloys laminated metal composite (LMC), with a great emphasis on the aging behavior of 7075Al. Microstructural evolution during different thermomechanical methods and their effect on mechanical behavior of Al/Al LMCs were studied. The result shows that superior combination of strength and ductility was achieved for Al/Al LMCs through rolling and aging. Compared to warm rolling, cold rolling had a significant improvement on mechanical properties after aging treatment, resulting from the high-density dislocations, increased microstrain and refined grains. Besides, anisotropy behavior of Al/Al LMCs fabricated by different TMTs was investigated and correlated with texture analysis. Evaluation of tensile test along the various orientations revealed that cold rolling process resulted in the enhanced anisotropy behavior, which was attributed to the formation of considerable rolling texture components and enhanced texture intensity after cold rolling.

在目前的研究中，开发了一种有效的热机械处理（TMT）以改善1100/7075铝合金层压金属复合材料（LMC）的力学性能，并着重于7075Al的时效行为。研究了不同热机械方法下的微观组织演变及其对Al / Al LMCs力学行为的影响。结果表明，通过轧制和时效，Al / Al LMC达到了强度和延展性的优异结合。与热轧相比，冷轧在时效处理后的机械性能有了显着改善，这归因于高密度位错，微应变增加和晶粒细化。此外，研究了不同TMT制备的Al / Al LMC的各向异性行为，并将其与织构分析相关联。
