Miniature Creep Rupture Testing of Steel comprising P91 (9 Cr 1 Mo-V) (Parent Constituent)

Temperature iso-stress miniature creep tests were conducted on P91 samples consisting of 9 Cr 1 Mo-V Steel under constant load and constant temperature in a vacuum environment on machines located at the Australian Nuclear Science and Technology Organisation. Test specimens conform to the nominal ratio of Lo=5D (6mm and 5mm Thread Diameter). Values for creep-extension, temperature and time were recorded at 30 minute intervals for the duration of the test.

本试验针对由9Cr-1Mo-V钢（9 Cr 1 Mo-V Steel）制备的P91试样（P91 samples）开展恒温恒应力微型蠕变试验，试验在真空环境、恒载荷与恒温条件下进行，试验设备设于澳大利亚核科学与技术组织（Australian Nuclear Science and Technology Organisation）。试验试样均符合Lo=5D的名义比例，螺纹直径涵盖6mm与5mm两种规格。试验全程以30分钟为间隔，记录蠕变伸长量、试验温度与试验时长数据。
