Fatigue crack propagation rates at high load ratio (R=0.9) were faster than those obtained at low load ratio (R=0.1) and there was no crack closure at high load ratio (R=0.9),indicating that fatigue crack propagation at high load ratio was mainly controlled by intrinsic factors such as microstructure.Fatigue crack growth resistances in seawater atmosphere were slightly lower than those in air,but showed theCited by 126Publish Year 1976Author D.Eylon,C.M.PierceFatigue Properties and Microstructure of SnAgCu Bi-Based Jun 23,2020 effect of microstructure on fatigue properties in low and#0183;Also,the fatigue performance of SnAgCuBi is close to SnAgCuBiSb in the accelerated test.But the SnAgCuBi alloy is estimated to have a longer characteristic life under low-stress amplitude cycling.The microstructure analysis shows a bismuth-rich phase formed around the Ag3Sn precipitates.
