ELASTIC FATIGUE IN TITANIUM STUDIES BY SCANNING ELECTRON-MICROSCOPY.
Abstract
A study by scanning electron-microscopy was made of the fatigue caused by nominally elastic amplitudes in a strain-aging metal (titanium) where minor impurities only suffice to confer a significant elastic range. These amplitudes produce point-extrusions, which are contrasted with the slip-zone extrusions produced by larger amplitudes starting plastic strain. These point extrusions apparently give rise to microcracks when they form a dense enough distribution. They seem to arise from a finer and more inherent structural fault than the coarse accidental faults to which elastic fatigue has previously been attributed. (Author)
