摘要： A metal body having high tensile strength and ductility at temperatures over 1000°F is provided. The body is prepared by hot isostatic pressing of powder formed by atomization of a melt of an alloy. The alloy composition base is according to the formula:
(Ni 1-x Al x ) 100-y B y
where x is between 0.23 and 0.25, and
where y is 0.1 to 2.0.
The consolidated body is suitable for machining and may be annealed for a couple of hours at temperatures between 800°C and 1200°C following such machining.-

摘要： 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 L1 2 type, such as nickel aluminide, 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 3° C/second to form a solid body, the principal phase of which is of the L1 2 type crystal structure in either its ordered or disordered state.
