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. An explicit finite element technique was used to evaluate the plastic strain distribution introduced by deformation in a specimen. The specimen was compressed by a pair of anvils controlled to keep the strain rate constant. The contact condition between the anvil and the specimen was determined by the experimental result from an identically deformed screw set in the specimen. The interrelation between the equivalent plastic strain Eeq, numerically obtained in the range 0.1 < Eeq < 4.2, and the experimental grain size of 2 - 9 μm was analysed. The change in ferrite grain size caused by Eeq in the unrecrystallised austenite region has been discussed.
