Abstract

Martensitic transformations of the TN-10 titanium-nickelide alloys doped with V, Nb, and Ag at a level of 1 at % are studied. It is shown that the alloying elements (Ag, Nb, and V) cause an increase in the elastic stress inside the B2-phase structure and the consequent increase in the start temperature of the direct martensite transformation. Vanadium significantly affects such a temperature and provides an increase by about 45°C. Complicated martensite transformations (B2 → R → B19') take place in alloys with vanadium and silver, and simple transformations (B2 → B19') occur in alloys with niobium.

不同合金添加量的钛镍合金的马氏体相变

摘要

研究了掺有1 at％的V，Nb和Ag的TN-10钛镍合金的马氏体转变。结果表明，合金元素（Ag，Nb和V）会导致B 2相结构内部的弹性应力增加，进而导致直接马氏体相变的起始温度升高。钒会显着影响该温度，并增加约45°C。钒和银的合金中发生复杂的马氏体转变（B 2→ R → B 19'），而铌的合金中发生简单的转变（B 2→ B 19'）。
