Crystallization temperature of amorphous electroless nickel-phosphorus alloys

摘要

Amorphous alloy is thermodynamically unstable, and it crystallizes after heat treatment. Considering ordered clusters as crystalline nuclei in amorphous electroless nickel-phosphorus alloy, crystallization thermodynamics and growth controlled by diffusion of nuclei were studied in detail. Crystallization temperature is determined when the size of nuclei is equal to the critical grain size at a heating rate. The simulated crystallization temperatures of alloys with various phosphorus contents are examined by experiment and other investigations under like conditions.
