Measurements of diffusion coefficients for Ni--Ti, Ni-Ti--Cr, and Ni--Ti- - Cr--W--Al alloys showed that the binary alloy had the highest diffusion coefficient at all temperatures. At temperatares up to 11OO deg the five component alloy had the lowest diffusion coefficient, at temperature above 11OO deg it becomes equal to the diffusion coefficient of the triple alloy, and at 1200 to 1250 deg it exceeds the diffusion of the triple alloy. The activation energy of diffusion for each alloy is 73.1, 84.0, and 91.3 kcal/g-atom for the binary, triple, and quintuple alloys, respectively. (R.V.J.)
