| Outline of Final Research Achievements |
Effects of a high magnetic field on diffusional transformtion behavior and structure are investigated. The magnetic moment of ferrite phase, which is necessary for the calculation of transformation temperature in a magnetic field, has been obtained by first-principles calculation. The magnetic moment of Fe increases with the addition of C,N and B. The magnetic moment of Fe with the addition of Al or Si decreases and that with Ni and Cu increases. The Ms temperature of 18 Ni maraging steel increases with the increase of applied magnetic field. The effects of a magnetic field on the spheroidization of pearlite was not observed.
