摘　　要：利用多向锻造和时效处理对2014铝合金进行了加工,研究了材料的微观组织、强度、硬度、塑性和滑动磨损性能。结果表明:晶粒细化导致材料具有较高的强度和硬度。多向锻造和时效处理后,较高的硬度以及磨损过程中较强的加工硬化大幅度增强了材料的抗滑动磨损性能。The 2014 aluminum alloy was processed by multi-directional forging and aging treatment.The microstructure,strength,hardness,plasticity and sliding wear properties of the material were studied.The results show that the grain refinement leads to higher strength and hardness of the material.The high hardness and the strong work hardening greatly enhance the wear resistance of the material after the multi-directional forging and aging treatment.
