Abstract
A method for achieving both improved strength and improved ductility in intermediate phases is provided. The method, briefly stated, comprises the steps of providing a melt whose composition substantially corresponds to that of a preselected intermetallic phase having a crystal structure of the Ll.sub.2 type, such as nickel alumininde, modified with from about 0.01 to 2.5 atomic percent boron, and modified further with cobalt substituent metal and rapidly solidifying the melt at a cooling rate of at least about 10.sup.3 .degree. C./second to form a solid body, the principal phase of which is of the Ll.sub.2 type crystal structure in either its ordered or disordered state.
