Abstract A systematical study was made of the tensile deformation behaviour of 4 different carbon steels, containing 0.10, 0.25, 0.39 and 0.71% C respectively, with initial austenite grain size 800μm under temperature 700—1300℃ at the strain rate 6.7×10~(-4)—6.7×10~(-2)S~(-1). It was indicated that the equation of deformation in the region of austenite phase controlled by the heat activation process is quite agreed with (?)=Aσ_M~nexp(-Q/RT) and the maximum deformation stress is decreased with the increasing of their C content. In the binary phase α+γ region, an embrittlement appears under temperature slightly lower than A_3 point and may become more or less to toughen as the increase of the C content.
