Abstract

The results of a recent investigation of fatigue crack growth in the gamma-based Ti-48at%Al alloy are presented. These include room- and elevated-temperature fatigue crack growth and crack closure data obtained at two stress ratios and temperatures. The possible role of oxide-induced closure at elevated temperatures is explored by use of a previously reported theoretical model, scanning Auger microscopy, and X-ray diffraction techniques. The results of deformation studies of the crack-tip region are also presented, and the micromechanisms of fatigue crack growth are elucidated. (A)
