The properties and microstructures of samples of Ti6Al4V, which have been produced from powder via HIPping (Hot Isostatic Pressing) have been assessed. The fatigue properties of samples which have different surface finishes have been compared. The samples with as-HIPped surface showed reduced fatigue properties when compared with samples which were either machined or electropolished after HIPping; these latter samples showed properties close to those of thermomechanically processed samples. In addition the tensile, fatigue and fracture toughness of samples manufactured using three different ranges of particle size, all of which had machined surfaces have been compared. Surprisingly the ductility of the samples made using the smallest powder particles was lower than the ductilities of those samples made using larger particles. On the other hand the tensile strength and the fracture toughness of all three samples were similar. The tensile strengths were similar to those of thermomechanically processed samples but the fracture toughnesses were all much higher.
