英文摘要	The effect of hot isostatic pressing treatment on the fatigue crack growth behavior of Ti-6Al-4V alloy fabricated by electron beam melting was investigated. The results indicate that the fatigue crack growth rate of the HIPed samples is higher than that of the as-fabricated one under certain stress intensity factor (Delta K < 18 MPa m(1/2)). With further increase in DK, the fatigue crack growth rates of the studied two samples become similar. The variation of a lamella thickness and the pore defects distribution have an effect on the fatigue crack growth rates in the studied samples, and the latter plays the dominant role.; The effect of hot isostatic pressing treatment on the fatigue crack growth behavior of Ti-6Al-4V alloy fabricated by electron beam melting was investigated.
