机械弛豫测量被广泛用于获得间隙溶质原子在体心立方金属中的扩散速率的信息。这种研究受到J·L·斯诺克发展的一个模型的刺激，该模型得出了松弛时间、实验参数和溶质原子扩散系数之间的关系。虽然Snoek模型对于碳或氮在α-Fe中的固溶体得到了很好的证实，但当弛豫研究扩展到V族过渡金属时，观察到了一些反常现象。通过考虑基于这些金属的固溶体的特殊性质，可以在Snoek模型的框架内考虑VA族金属的异常行为。通过各种弛豫技术获得了氧、氮和碳在钒、Nb(Nb)和Ta中的扩散数据。这些数据。
Mechanical relaxation measurements are used extensively to obtain information on the diffusion rate of interstitial solute atoms in body‐centered cubic metals. Such studies have been stimulated by a model, developed by J. L. Snoek, which yielded a relationship between a relaxation time, an experimental parameter, and the diffusion coefficient of the solute atom. Although Snoek's model was confirmed very well for solid solutions of carbon or nitrogen in α‐iron, a number of anomalies were observed when relaxation studies were extended to the group V transition metals.An extensive experimental study has been made of the factors that influence relaxation times. The anomalous behavior of the group VA metals can be accommodated within the framework of Snoek's model by taking account of the specific nature of solid solutions based on these metals.Diffusion data obtained by a variety of relaxation techniques are presented for oxygen, nitrogen, and carbon in vanadium, niobium (columbium), and tantalum. These data ...
