The effect of porosity on the mechanical properties of cast titanium alloy was investigated in this work, specifically for investment-cast Ti6Al4V. X-ray micro computed tomography (microCT) was used to non-destructively analyse pores in 10 samples prior to mechanical testing. A finite element analys...
