Abstract

Hot compression tests of a new CrMoV alloy for piston ring are conducted by Gleeble-3800 thermal mechanical simulation tester at the temperature of 950, 1000, 1050, 1100 and 1150 °C and strain rate of 0.01, 0.1, 1, 10 s−1. The results show that the true stress strain curves first go up to peak, and then go down to steady state in accord with characteristics of dynamic recrystallization, indicating that the main softening mechanism of this alloy during hot deformation is dynamic recrystallization. The hot deformation behavior of this alloy is characterized by Arrhenius hyperbolic sine relationship with the activation energy and stress index. On the basis of the true stress strain curves, the constitutive equation of the peak flow stress of this alloy is established. With the equation, the flow stress of this alloy can be predicated by numerical simulation for a new type piston ring.
