Rheological properties of carbon constructional quality steels

Abstract

Creeping performance is one of the typical rheological properties. Creep tests under the same temperature and different stress levels were done on carbon constructional quality steels, the integral creep constitutive equation and differential stress-strain constitutive relationship were established according to relevant rheological model, and the integral core of the creep was achieved through the experiments. Moreover, the coefficient related with viscosity of 35 steel was obtained through creep experiments’ data. The viscosity coefficients of TC11 titanium alloy and Lc4 aluminum alloy were also compared and analyzed.
