材料技术的不断更新和发展对传统测试技术提出了新的要求和挑战,尤其对于某些测试结果指标开始提出质疑。本文主要探讨关于测试钢材断裂韧性的问题,尤其关注于配备高端研究模型的落锤撕裂试样断裂性能实验设备的使用问题。
The continuous updating and development of material technology put forward new requirements and challenges for traditional testing technology. In particular, some of the indicators of testing result begin to be questioned. This article focuses on the issue of testing the fracture toughness of steels, with a particular focus on the use of experimental equipment for breaking performance of drop-weight tear specimens equipped with high-end research models.
