Fatigue life prediction based on a mechanism-based simulation of crack initiation and short crack growth in forged Ti-6Al-4V

摘要：

　　Ti-6Al-4V was experimentally investigated in two different forged conditions with respect to fatigue crack initiation mechanisms and growth characteristics of microstructurally short fatigue cracks.The experimental findings show that the stage of short fatigue crack propagation is strongly affected by the microstructure and widely controls fatigue life under the testing conditions applied.
