| Abstract: | The transformation kinetics of ferrite and perlite in hypoeutectoid alloy steel 40Cr has been studied by means of dilatometer and metalloscopy. The use of carbon equivalent to calculate the transformation kinetics equation of ferrite in hypoeutectoid alloy steel during A1-A3 temperature has been established. The turning point temperature below A1 temperature has been measured. The transformation of ferrite and perlite under turning point temperature conforms to Johnson- Mehl equation. The transformation kinetics equation of ferrite and perlite during turning point temperature ~A1 temperature has been discussed. |
