Study On Low-Cycle Fatigue Behavior Of Cast Hybrid Metal Matrix Composites

The low-cycle fatigue (LCF) behavior, especially the fracture initiation mechanism in a cast hybrid metal matrix composite (MMC), was studied experimentally and numerically. The conventional three-point bending fatigue test was carried out and fractographic analysis was conducted to observe the frac...
