Abstract: Single-stage and double-stage interrupted hot compression tests for simulating hot rolling have been carried out for a Ti-containing HSLA steel (10Ti). Physical simulation of hot rolling was in progress utilizing a Thermecmastor-Z simulator in 850~1150℃ and strain rate of 0.1~60 s-1.A model for residual strain ratio λ was designed, and a model of flow stress considering residual strain has been obtained. The hot deformation behaviour at various strain rates has been studied.
