Abstract
High‐frequency (15‐kHz) low‐strain fatigue measurements have been carried out on high‐purity polycrystalline aluminum, using a piezoelectrically driven exponential horn. The data show that ``channeling, similar to that observed in the deformation of irradiated metals, occurs prior to fatigue failure. Estimates show that the point‐defect concentration produced during high‐frequency fatigue can easily reach the critical concentration necessary for channel formation which has been found for irradiated metals. These observations suggest, therefore, that point defects may also play a critical role in the mechanisms of normal low‐frequency fatigue processes.This publication has 6 references indexed in Scilit:
