Abstract

A transition element-doped aluminum powder metal and a method of making this powder metal are disclosed. The method of making includes forming an aluminum-transition element melt in which a transition element content of the aluminum-transition element melt is less than 6 percent by weight. The aluminum-transition element melt then powderized to form a transition element-doped aluminum powder metal. The powderization may occur by, for example, air atomization.
