Uniaxial tensile test data for Gr. 91 material at 300 °C (sixteenth repeat test)

Data created at CVR during the KAMILE project on kinetics and mechanisms of crack initiation in liquid metal embrittlement (LME), funded by the GACR Grant Agency of the Czech Republic (c.n. 16-15008S) for fundamental science (2016-2018). The project is focused on the study of crack initiation in heavy liquid metal (HLM) environments at 300°C, in terms of threshold stresses and mechanisms. The steels considered are the ferritic-martensitic T91, the austenitic 1.4970 (15-15Ti), and (to a lesser extent) austenitic 316L. The environments are PbBi and Pb, with reference tests also performed in air for comparison.

本数据集由捷克科学基金会（Grant Agency of the Czech Republic, GACR）资助、项目编号为16-15008S的KAMILE项目于2016-2018年间在CVR生成，该项目面向基础科学研究，研究主题为液态金属脆化（liquid metal embrittlement, LME）中裂纹萌生的动力学与机制。该项目聚焦300℃下重液态金属（heavy liquid metal, HLM）环境中的裂纹萌生研究，重点探讨阈值应力与萌生机制。本次研究涉及的试验钢材包括铁素体-马氏体钢T91、奥氏体钢1.4970（15-15Ti），以及少量开展研究的奥氏体316L钢。实验环境介质为PbBi与Pb，同时设置空气环境下的对照试验以用于对比分析。
