摘要

摘要: 为测量460 MPa耐火钢的高温泊松比，在MTS809材料试验机上，完成460 MPa耐火钢室温、高温100~600℃拉伸与扭转试验，利用高温拉扭引伸计测定材料在不同温度下的弹性模量与剪切模量，根据泊松比、弹性模量与剪切模量的关系式，计算得到材料的高温泊松比。利用室温径向与轴向引伸计，通过拉伸试验测量得到460 MPa耐火钢室温泊松比为0.322，而拉扭试验测量计算材料室温的泊松比为0.335，误差仅为4%，验证了通过高温拉扭试验测量高温泊松比的可行性。

Abstract: In order to measure Poisson's ratios for 460 MPa heat-resisting steel at high temperature, tension and torsion tests for 460 MPa heat-resisting steel at room temperature and high temperatures of 100 to 600℃ were completed on the MTS809 material testing machine. The elastic modulus and shear modulus of the material at different temperatures were measured with using high temperature tension-torsion extensometers. According to the relations between Poisson's ratio and the elastic formation modulus Poisson's ratios of steel at high temperatures were calculated. Poisson's ratios of 460 MPa heat-resisting steel at room temperature were 0.322 measured with radial and axial extensometers, while Poisson's ratios at room temperature were 0.335 measured and calculated in tension and torsion tests,and the error was 4%, which verificed the feasibility of Poisson's ratios measured in tension and torsion tests at high temperature.
