含有 6 at.% Fe 及以上的 Ti-(50-x)Ni-xFe 合金没有表现出任何一级转变，但在物理性能上表现出异常，例如电阻率负温度系数、低德拜温度和比热曲线中的宽峰。这些异常现象可能与所谓的前兆现象有关。 (c) 2005 Acta Materialia Inc. 由 Elsevier Ltd 出版。保留所有权利。
Ti-(50-x)Ni-xFe alloys containing 6 at.% Fe and more do not show any first order transformation, but show anomalies in their physical properties such as a negative temperature coefficient of electrical resistivity, low Debye temperature and a broad peak in specific heat curve. These anomalies may be related to the so-called precursor phenomena. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
