摘要

本文研究了淬火低镍 (Ni49.5Ti35.5Hf15)100-XNbX 和富镍 (Ni50.3Ti34.7Hf15)100-XNbX 合金（X = 0，15% Nb）的合金化对 B2-B19' 马氏体转变、粘弹性能和显微组织的影响。将低镍和富镍合金与 Nb 进行合金化，可在（Ti，Hf）2Ni 相中析出 β-Nb 相。合金化后，低镍合金的转变温度和奥氏体弹性模量降低，而富镍合金的转变温度和奥氏体弹性模量升高，从而使它们变得相似。

Microstructure and Thermoelastic Martensitic Transformation in Ni-Low and -Rich Ni–Ti–Hf–Nb Hightemperature Shape Memory Alloys

The paper studies the alloying effect of the quenched Ni-low (Ni_49.5Ti_35.5Hf₁₅)_100–XNb_X and Ni-rich (Ni_50.3Ti_34.7Hf₁₅)_100–XNb_X alloys (X = 0, 15 at.% Nb) on the B2-B19' martensitic transformation, viscoelastic properties and microstructure. Alloying of Ni-low and -rich alloys with Nb, provides the β-Nb phase precipitation within the (Ti, Hf)₂Ni phase. After alloying, the transformation temperature and austenite elastic modulus decrease in Ni-low alloys and increase in Ni-rich alloys, thus making them similar.
