Initiation and growth of short fatigue cracks in austenitic Sanicro 25 steel
Original language description
Austenitic heat‐resistant stainless steel Sanicro 25, often used in energy productionninstallations, was cyclically strained at room temperature, and initiationnand growth of short fatigue cracks have been studied. Cylindrical specimensnwith pre‐existing shallow notch were cyclically strained under constant totalnstrain amplitudes, while the surface relief, crack initiation, and short crackngrowth were observed, in‐situ, using optical and electron microscopes.nPersistent slip markings were found to be the principal locations where naturalnfatigue cracks initiated. The character of the crack paths of short cracks wasnstudied using SEM and EBSD techniques. The results exhibit prevailingntransgranular crack growth, ie, along the persistent slip markings within thengrains. The growth of the largest cracks in the central part of the shallow notchnwas measured for different applied strain amplitudes. Because the coalescencenof initiated cracks plays a significant role during crack growth, the use of then“equivalent crack” concept gives adequate results in the description of the crackngrowth rate. The crack growth law of short cracks was established andncompared with the Manson‐Coffin law of the material.
