Effect of Nd Addition on the Microstructure and Martensitic Transformation of Ni-Ti Shape Memory Alloys

The effect of rare earth element Nd addition on the microstructure and martensitic transformation behavior of Ni50Ti50−xNd x ( x = 0 , 1, 3, 7, 20) shape memory alloy was investigated experimentally. The results showed that the microstructure of Ni-Ti-Nd ternary alloy consists of the NiNd phase and...

Zusammenfassung:	The effect of rare earth element Nd addition on the microstructure and martensitic transformation behavior of Ni50Ti50−xNd x ( x = 0 , 1, 3, 7, 20) shape memory alloy was investigated experimentally. The results showed that the microstructure of Ni-Ti-Nd ternary alloy consists of the NiNd phase and the NiTi matrix. One-step martensitic transformation was observed in all alloys. The martensitic transformation start temperature M s increased gradually with increasing Nd content for Ni-Ti-Nd alloys.
