    Abstract

    The thin-walled effects of a new directionally solidified superalloy were investigated aiming at tubular hollow specimens with wall thickness of 1.0,1.2,1.4 mm similar to the hollow blades made by the net-shape investment casting.The results showed that the stress-rupture of the thin-walled specimens can not be obviously reduced by comparing with that of the standard ones with the diameters of 5mm,indicating the alloy has no obvious thin-walled effects for the experiment condition.The experimental results were analyzed from the view of processing factors and microstructure.
