Abstract

Influence of longitudinal and torsional bias stresses on anomalous amplitude-dependent internal friction was studied. The longitudinal bias stress may always weaken the anomalous amplitude-dependent effect, while the torsional one induced different effects depending on the directions applied. Bias stress effect exists only in those alloys undergone certain heat treatment or cold working. The anomalous amplitude-dependent internal friction peaks, P₃, P₂ and P₁ are found to be related closely to the slant dislocation kink chains. Thus, the application of bias stress to internal friction would be contributed to the study of dislocation structures.
