- The next Generation-IV reactors need to be stand for a very high temperature. Structural materials have to resist that temperature; otherwise, damages could appear. G115 steel is a candidate structural material which has been considered in this work. The hot deformation behavior of G115 steel was carried out at elevated temperatures 500, 550 and 600°C with different strain rates ranging from 1x10-5 to 1x10-3 s-1. To derive the hot deformation constitutive equation, the universal hyperbolic-sine Arrhenius-type equation was utilized considering the ultimate stresses values for each condition. As a result, the activation energy of G115, which will assess the high-temperature deformation mechanism, was obtained to be 331 KJ/mol.
