Abstract

The 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 may induce different effects from different directions applied. Bias stress effect exhibits only in properly heated treated and cold worked alloy specimens. The anomalous amplitude-dependent internal friction peaks, P₃, P₂ and P₁, are found to be related closely to slant dislocation kink chains. Thus, the application of bias stress to internal friction would be contributed to the study on dislocation structure.
