摘　　要：通过对铝合金拉伸试样进行车削破坏,研究试样表面质量对不同合金拉伸性能的影响,以及对不同状态同种合金拉伸性能的影响;同时研究不同拉伸速度对铝合金拉伸性能的影响。由此了解试样表面质量和拉伸速度对性能的影响规律,并在实际检测过程中尽量避免表面质量和拉伸速度产生的影响。By turning damage to the tensile specimen of aluminum alloy , affect the surface quality of the specimen on tensile properties of different alloys , as well as the influence on the tensile properties of different states of the same alloy are studied , at the same time , the effect of different strain rate on tensile properties of aluminum alloy are also studied .The influence of surface quality and drawing speed on the properties of the samples is understood in order to avoid the affect of the surface quality and drawing speed of the actual testing process .
