抄録

In order to obtain sintered FeSi₂, the mixed powder of Fe and Si has been hipped at below the decomposition temperature of 986°C. In this process, the reaction and the densification have been proceeded simultaneously. Before the hipping of powders, the reaction of Fe plate and Si plate was examined to understand the reaction of Fe and Si under hipping condition. It was found that high temperature and low pressure accelerated the reaction. Based on the results, hipping conditions of the powder were decided. Single phase of FeSi₂ was obtained under the hipping condition of 850 - 900°C, 50MPa and 30min -4hours. However, the relative densities of the hipped specimens were 82 - 90%. To obtain higher density, the mixed powder was hipped under 50 MPa to be caused the reaction completely, and then was densified under high pressure of 200MPa. Applying this 2 stage hipping, the relative density increased up to 98%. It is concluded that HIP technique is useful for the materials which transform at high temperature.
