Study of tensile constitutive model on T92/HR3C dissimilar steel welded joint

Abstract High-temperature short-time tensile tests were carried out on T92/HR3C dissimilar steel welded joints and base materials at 610°C with different loading rates, and the effects of different loading rates and strains on the tensile mechanical behaviours of T92 steel and T92/HR3C welded joints were analysed. The study shows that the multilinear model can better reflect the material tensile intrinsic relationship.
