To achieve drastic cost reduction and stable supply of Ni-base single crystal superalloy turbine blades, we proposed direct recycle method that includes collecting of the components, remelting and refining in the CaO crucible, adjusting composition using the °Counter Alloying Method", and recasting into single crystals. In this study, used and scrapped Ni-base single crystal superalloy PWA1484 turbine blades were directly recycled and the properties of the recycled materials were evaluated by performing high temperature tests such as creep, cyclic oxidation, and high cycle fatigue. The recycled material showed properties equal to or better than the genuine ingot material.
