Fatigue performances of selective laser melted Ti-6Al-4V alloy: Influence of surface finishing, hot isostatic pressing and heat treatments
International Journal of Fatigue(2019)
摘要
•Surface finishing improves the fatigue performances of SLMed Ti-6Al-4V.•HIP and heat treatments coarsen the α laths and improve the ductilities.•HIP and heat treatments increase the fatigue limits of SLMed Ti-6Al-4V.•Pores accelerate the fatigue crack initiation and lower the fatigue limit.
