能量耗散率评价及高温性能原位测试新技术与新设备

      工程材料在不同条件下的弹性与塑性可以简单地用硬度压痕的载荷位移曲线来确定。作为测试难点的高温环境下的材料性能评价也可以通过高温可视化原位试验得以实现。为了实现高温环境材料的物理性能评价,提出间接测试的相对法,配合原位试验机可解决常规方法难以解决的各种性能检测难题。本报告简介能耗散率及其高温性能评价新技术,以及材料压痕仪与高温可视化原位测试仪器和相应的测试方法。通过可视化高分辨摄像解决高温受力-变形和高温裂纹张开的非接触精密监测,对于陶瓷的烧结变形、高温弹性模量、陶瓷涂层热应力分析、高温硬度、高温能量耗散等高温性能的分析和直观了解具有重要实用价值。

The material performance under high temperature environment is very important for the reliability and durability of service components, and tests in-situ is a difficult in the field of high temperature. In order to evaluate the physical properties of materials in high temperature environment, a relative method of indirect testing is proposed. With the help of in-situ testing machine, various testing problems that are difficult by conventional methods can be solved. This report introduces the relative method and an evaluation technology for high-temperature performance, as well as the high-temperature visual in-situ tester. The non-contact precision monitoring of stress-deformation and crack opening at high temperature can be realized by visualized high-resolution camera, which has important practical value for the analysis and master of high temperature properties such as ceramic sintering deformation, high-temperature elastic modulus, thermal stress analysis of ceramic coating, high-temperature hardness, high-temperature energy dissipation etc.
