Hexagonal-Close-Packed Phase Stability in the Cobalt-Molybdenum System: Further Confirmation of the Brewer-Engel Theory

摘要

Solid state catalysis and a thermal gradient furnace technique have been used to investigate the sluggish low-temperature hexagonal close packed to cubic close packed phase transformation in the molybdenum-cobalt system. The addition of molybdenum stabilizes the hexagonal phase of cobalt to a higher temperature as pedicted by the Brewer-Engel correlation for bonding in metals. The maximum temperature at which this hexagonal phase exists in 849 exp 0 C. (ERA citation 07:004708)
