Abstract
Low frequency internal friction (~1Hz) of Nb-2at%M-H alloys (M=Ti, Zr, Cr, Mo) has been measured over a temperature range from 5 to 300 K. Relaxation peaks are observed below 100 K for specimens containing Ti and Zr, but not for the other specimens. These peaks are considered to be due to relaxation of substitutional (M)-interstitial (H) complexes. The characteristics of the peaks are discussed in comparison with those in V-base alloys.
