STRUCTURE STUDY OF AN AMORPHOUS ELECTRODEPOSITED NICKEL-PHOSPHORUS ALLOY.

Abstract

The radial distribution function for an electrodeposited amorphous nickel-phosphorus (14.9 wt % P) alloy has been determined. The atomic distribution was found to be similar to that in a monatomic liquid metal, and more disordered than that observed in an amorphous nickel-phosphorus alloy produced by chemical deposition. Two transformations (both exothermic) were observed in this alloy; the first of which occurred at 280 plus or minus 2C with an energy of 18.5 cal/gm (960 cal/gm atom) and the second at 410 plus or minus 5C with an energy of 6.0 cal/gm (310 cal/gm atom). As deposited the alloy exhibits only a very weak small angle X-ray scattering, apparently not due to the presence of the phosphorus. (Author)
