Owing to high hardness, compressive and extremely good corrosive resistances alumina is one of the mostly used turbo materials. In last few decades few of studies have been done on the dependency of grain size on impact fatigue behavior of alumina.B. K .Sarkar and T.G.J Glinn (1969) studied the impact fatigue of an alumina ceramic and exhibit fatigue behaviors, having a high stress plateau followed by progressively increasing endurance with decrease in applied impact energy. S Maity and B.K.Sarkar (1994) studied the impact fatigue of a porcelain ceramic and showed a definite fatigue behavior with increasing endurance in decreasing impact energy levels and cumulative residual stress is suggested to explain the fatigue behaviors. S. Maity, D. Basu and B.K. Sarkar (1994) studied the fatigue behaviors of fine-grained alumina under repeated impact loading and found that the fatigue resistance parameter is 17.12 while the endurance limit is around 270Mpa which is about 38% of the single impact strength of the material and also found that fatigue cracks are trans-granular near the crack initiation region, the rest being inter-granular. Manabu et al (2002) studied the material response to particle impact during abrasive jet machining of alumina. A relatively smooth face can be produced when silicon carbide (GC) abrasive is employed. The fatigue behaviour of fine-grained alumina hip joint heads under normal walking load has also been reported by Basu et al (2005) and found that the alumina femoral heads have successfully withstood 107 cycles at maximum walking stress of 17.2 KN, which is equivalent to a body weight of 400Kg. The femoral heads didn't exhibit any sub-critical crack growth at the maximum walking load of 10KN, indicating the quasi-infinite performance life in-patient up to body weight of 250 Kg.
