doi:10.3901/JME.2021.16.218

Abstract

Abstract: Brazing technology is widely used for manufacturing the high efficiency and compact heat exchanger applied in the fields of aerospace and nuclear power, etc. The creep and creep crack growth caused by the creep damage are one of the main failure modes for heat exchanger working at high temperature and pressure conditions. The Inconel625/BNi-2 and C276/BNi-2 brazed joint are adopted to investigate the creep deformation and creep crack growth behavior of the brazed joint, the creep deformation and crack growth characteristics of the brazed joint are obtained, and the creep failure mechanism of the brazed joint is clarified. Meanwhile, the creep damage and life prediction of the brazed joint are investigated and reviewed by using the creep damage constitutive model and experimental results. Based on the experimental and creep damage constitutive model analysis, effect of brazing technology, mechanical properties of diffusion zone and geometrical size on the creep crack behavior of the brazed joint are discussed, and the creep constraint parameter is proposed. At last, the size effect of creep crack growth behaviors for the brazed joint is successfully characterized by the creep constraint parameter. The life prediction method mentioned in present paper can provide the theoretical direction for the integrated life prediction from material-component to equipment.
