摘要
The structure of NiTi shape memory alloy nanoparticles was determined by high-resolution electron microscopy. The mixture of Ni4Ti3 and R-phases was observed, which clearly showed lattice relationships of (2 (1) over bar 1)(B2)//(1 0 1)Ni4Ti3 and (2 (2) over bar 0)(B2)//(1 3 1)Ni4Ni3. Lattice images of an R-phase particle suggested the existence of a Ni-rich Guinier-Preston zone (G.P. zone). (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
