MEACTOS environmentally-assisted crack initiation data for constant extension rate tensile tests in BWR/NWC and PWR environments on Alloy 182 Ni-based alloy

Data collection created at PSI, SCK CEN, CIEMAT, VTT, ZAG, Framatome GmbH, University of Manchester, and RATEN ICN in the scope of the H2020 MEACTOS project investigating the mitigation of environmentally-assisted cracking through optimisation of surface condition. The work was concerned with SSRT/CERT accelerated tests on flat tapered tensile specimens in BWR/NWC and PWR environments to determine the stress corrosion cracking threshold stress. The material investigated was Ni-based weld metal Alloy 182.

本数据集由PSI、SCK CEN、CIEMAT、VTT、ZAG、法马通有限公司（Framatome GmbH）、曼彻斯特大学以及RATEN ICN在欧盟地平线2020（Horizon 2020）计划的MEACTOS项目框架下创建。该项目旨在通过优化表面状态缓解环境辅助开裂问题，研究工作针对镍基焊缝金属合金182（Alloy 182）展开，在沸水堆（Boiling Water Reactor, BWR）/正常水化学工况（Normal Water Chemistry, NWC）及压水堆（Pressurized Water Reactor, PWR）环境中，对扁平锥形拉伸试样开展慢应变速率拉伸试验/恒延伸率拉伸试验（Slow Strain Rate Testing, SSRT / Constant Extension Rate Testing, CERT）加速测试，以测定应力腐蚀开裂临界应力。
