The longitudinal bias stress may always weaken the anomalous amplitude-dependent effect, while the torsional one may induce different effects from different directions applied. Bias stress effect exhibits only in such alloy undergone proper heat treatment or cold working. The anomalous amplitude-dependent internal friction peaks, P_3, P_2 and P_1, are found to be related closely to slant dislocation kink chains. Thus, the application of bias stress to internal friction would be contributed to studying dislocation structure.
