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 calgm 960 calgm atom and the second at 410 plus or minus 5C with an energy of 6.0 calgm 310 calgm 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
