| Abstract: | The lifetime of a specimen under cyclic loading is usually limited by the initiation and growth of microcracks. Experimental results for the austenitic stainless steel X6 CrNiNb 18-10 are given and a model for crack initiation and crack growth in the first grains of a polycrystalline aggregate is proposed. |
| Keywords: | Stainless steel Fatigue Crack initiation Microstructurally small cracks Crack growth |
