Funded Activity Summary

Design of Improved Shape Memory Steels by Control of Parent Phase Precipitation Strengthening and Stacking Fault Energy. The aim is to develop iron-based precipitation strengthened shape memory alloys that are capable of recoverable strains > 4% and stresses > 200 MPa, for application as low cost one-way memory devices. Innovative solid solution and precipitation strengthening strategies will be employed to modify dislocation behaviour and stacking fault energy and to improve the reversibility of the martensitic transformation - the key to shape memory behaviour. The interaction of transformation dislocations with strain fields due to coherent particles and solute atoms will be elucidated. Significant increases in shape recovery stress and strain are expected because of increased alloy resistance to irreversible plastic strain.
