N2 - The accumulation of cyclic plasticity in bond coat (BC) is a key factor controlling the displacement instability of the thermally grown oxide (TGO) in thermal barrier systems. The cyclic plasticity is affected by the properties of constituent materials, which vary observably with the service temperature. A numerical model accounting for the behavior of creep and thermal growth in TGO under thermal cycling is used to explore the effect of temperature-dependent properties on cyclic plasticity in BC. The influence of temperature-dependent Young's modulus of thermal barrier coating (TBC), TGO, BC and substrate, thermal expansion coefficients of TBC, BC and substrate, and the yield strength of BC on cyclic plasticity in BC are discussed respectively.
