ABSTRACT:
Methods of producing atomized intermetallic aluminide powders with a controlled oxygen content, and articles made from the powders by powder metallurgical techniques are disclosed. Gas atomized intermetallic aluminide powders can be oxidized to increase their oxygen content. Water atomized intermetallic aluminide powders can be milled to change their size, shape and/or oxygen content. Blends or mixtures of modified gas and water atomized intermetallic aluminide powders can be processed into articles by powder metallurgical techniques.
