摘要
本研究对工业用T2纯铜进行了单轴拉伸试验研究,旨在系统获取其基本力学性能参数。通过电液伺服拉扭试验机开展单轴拉伸试验,结合高温引伸计测量应变,获得了纯铜在拉伸过程中的应力-应变曲线及相关力学参数。试验结果表明,T2纯铜的弹性模量为110.8 GPa,屈服强度(σ_(0.2))为30.1 MPa,抗拉强度为199.6 MPa,断后伸长率为57.5%,断面收缩率为71.1%,断裂应变为1.24。本研究为纯铜在实际工程中的力学性能评估提供了试验依据。
This study conducts a uniaxial tensile test on industrial T2 pure copper to systematically obtain its basic mechanical performance parameters.The uniaxial tensile experiment was carried out using an electro-hydraulic servo tensile and torsion testing machine,and the strain was measured by a extensometer.The stress-strain curve and related mechanical parameters of pure copper during the tensile process were obtained.The test results show that the elastic modulus of T2 pure copper is 110.8 GPa,the yield strength(σ0.2)is 30.1 MPa,the tensile strength is 199.6 MPa,the elongation after fracture is 57.5%,the reduction of area is 71.1%,and the fracture strain is 1.24.This study provides experimental basis for the mechanical performance evaluation of pure copper in practical engineering.
