Abstract

The interaction between molybdenum and phosphorus atoms in iron is discussed using the results of resistivity measurement and Mössbauer spectroscopy of FeMoP alloys. The results of resistivity measurement show that an attractive interaction exists between molybdenum and phosphorus. The binding free energy of pairs consisting of a molybdenum atom and a phosphorus atom is estimated to be less than about 8 kJ mol-1 at 1323 K. The rate of precipitation is investigated in supersaturated FeMo and FeMoP alloys. The addition of phosphorus enhances the precipitation rate. The results can be attributed to the attractive interaction between molybdenum and phosphorus, which results in an increased number of precipitate particles in the ternary alloy.
