  • The deformation characteristics of 50kgf/$\textrm{mm}^2$ grade steels were studied numerically and experimentally to investigate the effects of the size, shape, distribution and volume fraction of the second phase on mechanical properties. Flow curves of ferrite calculated by Tomota's experimental equation was modified to take into account yield point phenomena of steels. The predicted tensile properties by modified Tomota's method were in good agreements with measured data.
