Analysis for Flow Stress Model of 33Mn2V Steel

Abstract

Hot compressive deformation behavior of non-modulation 33Mn2V steel for oil well tube was studied by compression tests using Gleeble-1500 thermal simulation machine conducted at the temperatures from 750°Cto 1200°Cand at the strain rates of 0.01 s−1 to 0.16 s−1. Using non-linear regression method to establish a Kumar model to predict the hot deformation behavior of 33Mn2V steel. Results show that the errors of the Kumar model between experimental data and calculated results are less than 10%. The deformation activation energy of 342.1841kJ/ mol. The average dynamically recrystallized grain size reduces with decreasing temperature.
