Abstract
The relaxation of a substitutional-tetrahedral interstitial atom pair in the bcc lattice is studied theoretically. Three relaxation modes can be excited mechanically, one by a tensile stress along the <111> direction and the other two by the <100> direction. The kinetics of the <100> relaxation are examined in detail. Experimental results of internal friction studies on Nb-Ti-H and V-Ti-H alloys are discussed in the light of the present analysis.
