The brazed structures have geometrical discontinuities like fillets working as notches. These notches have great effect on creep crack initiation and propagation. This paper studies the notch effect on creep damage for Hastelloy C276-BNi2 brazed joint, and the effects of notch type, notch radius and notch angle on creep damage have been investigated. The results show that the creep damage initiates...
Nickel-based brazed joints are widely used at high temperatures, and it is very important to ensure the creep strength. Using three-dimensional finite element method, this paper presents a study on the creep damage and creep crack initiation (CCI) in P92–BNi2 brazed compact tension (CT) joint specimen, and the effect of brazed residual stress on CCI has been investigated. Firstly, the as-brazed residual...
