摘要
The effect of yttrium on the oxidation resistance of as-cast Ti2AlNb based alloy was studied.With the addition of Y,the oxidation resistance of the experimental alloys was improved at 700-850 ℃.The improvement of the oxidation resistance was attributed to the refinement of the oxide scale and the appearance of transition layer.
