Full-size Creep Rupture Testing of Steel comprising 1/2 Cr 1/2 Mo 1/4 V (Parent constituent)

Temperature iso-stress full-size creep tests were conducted on 1/2 Cr 1/2 Mo 1/4 V Steel under constant load and constant temperature in an argon environment on machines located at the Australian Nuclear Science and Technology Organisation Test specimens conform to the nominal ratio of Lo=5D (16mm thread diameter). Values for creep-extension, temperature and time were recorded at 30 minute intervals for the duration of the test.

本研究针对1/2Cr-1/2Mo-1/4V钢开展全尺寸等温等应力蠕变试验，试验于氩气环境中、恒定载荷与恒定温度条件下进行，试验设备设于澳大利亚核科学与技术组织（Australian Nuclear Science and Technology Organisation）。试验试样符合Lo=5D的名义比例要求（螺纹直径为16mm）。试验全程以30分钟为间隔，记录蠕变伸长量、试验温度与加载时长的相关数据。
