FATIGUE CRACK PROPAGATION OF Ni-BASE SUPERALLOYS L.Z.Ma1,E.Barbero1,X.B.Liu1,K.M.Chang1 (1.Dept. of Mechanical & Aerospace Engineering, West Virginia University, Morgantown,WV 26506-6106, USA) Abstract:Time-dependent Fatigue Crack Propagation (FCP) behaviors of five Ni-base superalloys were investigated at various temperatures under fatigue with various holding times and sustained loading......
under impact load is divided into two aspects, the crack initiation behavior and the crack propagation. Fatigue crack propagation under repeated impact load is an important aspect of metal fatigue under... and crack propagation velocity were deduced. The effects of impact pattern characteristic parameters such as impact range and time interval on impact fatigue crack growth and propagation rates were......
