Effect of plastic strain on grain size of ferrite transformed from deformed austenite in Si-Mn steel

The effect of plastic strain on the grain size of ferrite transformed from deformed and unrecrystallised austenite has been investigated for a low carbon Si-Mn steel. The interrelation between the equivalent plastic strain epsiloneq, numerically obtained in the range 0, 1<epsiloneq<4, 2, and the experimental grain size of 3-8 m was analysed. The change in ferrite grain size caused by epsiloneq in the unrecrystallised austenite region has been discussed.
