Abstract：In order to study the flow law of components of 1020 steel formed by cold-beating, the room temperature quasi-static compressive tests and dynamic compressive tests with strain rate of 2 000~4 000 s-1 and 1020 steel temperature of 100~400 ℃ were conducted, the effects of dynamic mechanical properties, strain rate and temperature on the flow stress were investigated, and the constitutive model of 1020 steel was established.Modified JC model was established based on experimental results.Using standard statistical parameter method, comparison and analysis were made on the modified JC model, standard JC model and experimental results.The results revealed that the modified JC model possesses better capability in describing the relations between flow stress and strain, strain rate and temperature of 1020 steel.
