Abstract

The structure of NiTi shape memory alloy nanoparticles was determined by high-resolution electron microscopy. The mixture of Ni4Ti 3 and R-phases was observed, which clearly showed lattice relationships of (21̄1)B2//(101)Ni4Ti3 and (22̄0)B2//(131)Ni4Ti3. Lattice images of an R-phase particle suggested the existence of a Ni-rich Guinier-Preston zone (G.P. zone).
