Xu, Qihua, Xu, Qiang, Pang, Yongxin and Short, Michael (2013) Review of Creep Cavitation and Rupture of Low Cr Alloy and its Weldment. Advanced Materials Research, 744. pp. 407-411. ISSN 1662-8985
Abstract

This paper presents a review of creep cavitation and rupture of low Cr alloy and its weldment, particular in the heat-affected zone (HAZ). Creep damage is one of the serious problems for the high temperature industry. One of the computational approaches is continuum damage mechanics which has been developed and applied complementary to the experimental approach and assists in the safe operation. However, the existing creep damage constitutive equations are not developed specifically for low stress. Therefore, in order to form the physical bases for the development of creep damage constitutive equation, it is necessary to critically review the creep cavitation and rupture characteristics of low Cr alloy and its weldment.
