ABSTRACT
Most creep rupture is caused by the cavitation at the grain boundary. Hence, it is vitally important to develop a creep cavitation model as it is the prerequisite for the development of the creep cavitation rupture model. Due to the experimental difficulty, it is rare to conduct interrupted creep tests to measure cavity growth. However, cavity histograms were more regularly produced and reported to quantitatively report and record the cavity distribution. This research group originally developed such a concept, method and the procedure to calibrate the cavitation model reversely based on the cavity histogram. This paper reports and summarises the method and procedures for the calibration of the creep cavitation model based on the cavity histogram.
