摘要

摘要计算了取代原子以孤立原子和成对原子形式存在的三元合金的Snoek效应的阻尼谱。计算预测除了普通的Snoek峰外，还会出现两个峰P1和P2。P2峰与靠近对的间隙原子有关，而P1峰由靠近对的间隙原子和靠近孤立取代原子的间隙原子组成。本理论还预测，如果直接跃迁的活化能非常高，间隙原子在对(P2)周围的弛豫可能通过旁通扩散发生。

Theory of the Snoek Effect in Ternary B.C.C. Alloys : V. Effect of Pairing Substitutional Solute Atoms

Abstract The damping spectrum of the Snoek effect is calculated for ternary b.c.c. alloys in which substitutional atoms exist both as isolated and as paired atoms. The calculation predicts the appearance of two peaks, P1 and P2, in addition to the ordinary Snoek peak. The peak P2 is associated with interstitial atoms in the vicinity of pairs, while the peak P1 consists of contributions from interstitial atoms near pairs as well as those near isolated substitutional atoms. The present theory also predicts that the relaxation of interstitial atoms around pairs (P2) may occur through by-pass diffusion if the activation energy for direct jumps is very high.
