Study on High Cycle Fatigue Life of the Isostatically Pressed Beryllium Material AITranslate
Abstract AITranslate
High-cycle fatigue tests of the isostatically pressed beryllium material were carried out using the pull-pull loading method.The S-N curve was drawn according to the test data to obtain its fatigue limit,and the fatigue fracture morphology was observed using a scanning electron microscope.The results show that fatigue limit of the isostatically pressed beryllium material is 385 MPa,corresponding to the specified fatigue life of 10~7 times.Fatigue cracks initiate at the edge of the beryllium sample,and the cracks cross the grain boundary and grow up with microcracks in the adjacent grains.The beryllium sample instantaneously cleaves and fractures,forming the fracture morphology mainly consisting of fatigue sources and radiation zones.The size of the fatigue source increases with the decrease of the maximum cyclic stress.
