用高分辨电子显微镜对NiTi形状记忆合金纳米颗粒的结构进行了表征。(21̄1)B2//(10 1)Ni4Ti3和(2 2̄0)B2//(13 1)Ni4Ti3的晶格关系清晰。R相粒子的点阵图像表明存在一个富镍的Guinier-Preston区(G.P.区)。
The structure of NiTi shape memory alloy nanoparticles was determined by high-resolution electron microscopy. The mixture of Ni4Ti3and R-phases was observed, which clearly showed lattice relationships of (21̄1)B2//(101)Ni4Ti3and (22̄0)B2//(131)Ni4Ti3. Lattice images of an R-phase particle suggested the existence of a Ni-rich Guinier–Preston zone (G.P. zone).
