This transition follows an Arrheniustype rate law which relates the relaxation time
to make the jump with the temperature and the activation energy required for the
jump . Since the internal friction is related to the frequency of the periodic stress ...

They concluded that the abnormal peak in Fe - V - N alloys was caused by two
relaxation processes , one associated with the nitrogen atom jumps associated
with Fe - V sites , and the other with jump processes involving preferred sites in
the ...

Their explanation of the jump process is as follows . If a N atom associated with a
silicon atom diffuses along the same path as in alpha iron , the saddle point for
the diffusion is the tetrahedral position ( marked T in Fig . 33 ) . Unfortunately the
...
