Abstract

TRIP (Transformation induced plasticity) steel has a good combination of high strength and high plasticity which depend on the micro phase transformation and staking fault development greatly. C atom was typical alloying agent of austenite and plays an important role in austenite behavior, especially for staking fault nucleation. As a micro materials behavior, molecular dynamics simulation was carried out to discuss the effect of C atom on the staking fault nucleation. From the simulation result we can find that carbon influence the staking fault nucleation greatly, with the increasing of the number of C atoms, strain for staking fault form decreased, system with 4 C atoms staking fault formed when strain was 7.5% and for system without C atoms there are no staking fault with local tension strain up to 10%. Under the same deformation, stacking fault distribution was uniform for the system with 1 carbon and become uneven with the increasing of the C atom.
