Molecular dynamics simulation of the α-γ phase transition in iron-nickel system — •Emilia Sak-Saracino and Herbert M. Urbassek — Physics Department and Research Center OPTIMAS,Erwin-Schrödinger-Straße, 67663 Kaiserslautern, Germany

Using molecular dynamics simulation, we study the austenite-martensite phase transition in the iron-nickel system. During a heating/cooling cycle, the phase transition can be observed by monitoring the hysteresis of the system volume with temperature. We find that with increasing nickel concentration, the martensite and austenite temperatures decrease, in agreement with experiment.
