Abstract
Fine-grained alumina prepared by usual cold isostatic pressing sinteri ng process was investigated for fatique behaviour under repeated impac t loading. The fatigue resistance parameter ws found to be 17.12 while the endurance limit was around 270 MPa which was about 38% of the sin gle impact strength of the material. Fatigue cracks were found to be t ransgranular near the crack initiation region, the rest being integran ular.
