高温硬度试验应用广泛，但缺乏试验标准。本研究的目的是建立高温硬度与高温准静态压缩试验之间关系的有限元模型，这是一种成熟的试验技术和试验标准。进行了高温准静态压缩试验和高温硬度试验。通过高温压痕有限元模拟，建立了高温、准静态压缩试验结果与高温硬度试验结果之间的关系。将高温硬度的模拟结果与实验结果进行了对比，验证了高温压痕有限元模拟的准确性，模拟结果表明，在忽略压痕过程中材料堆积的情况下，高温硬度基本不随载荷的变化而变化。模拟和实验结果表明，硬度的降低和热软化是一致的。根据模拟的压痕轮廓对压痕的应变和应力进行了分析。结果表明，应变随试验温度的升高而增大，应力随试验温度的升高而减小。
The high-temperature hardness test has a wide range of applications, but lacks test standards. The purpose of this study is to develop a finite element method (FEM) model of the relationship between the high-temperature hardness and high-temperature, quasi-static compression experiment, which is a mature test technology with test standards. A high-temperature, quasi-static compression test and a high-temperature hardness test were carried out. The relationship between the high-temperature, quasi-static compression test results and the high-temperature hardness test results was built by the development of a high-temperature indentation finite element (FE) simulation. The simulated and experimental results of high-temperature hardness have been compared, verifying the accuracy of the high-temperature indentation FE simulation.The simulated results show that the high temperature hardness basically does not change with the change of load when the pile-up of material during indentation is ignored. The simulated and experimental results show that the decrease in hardness and thermal softening are consistent. The strain and stress of indentation were analyzed from the simulated contour. It was found that the strain increases with the increase of the test temperature, and the stress decreases with the increase of the test temperature.
