Claim 6:
7. The method of producing a Fe-based sintered body as set forth in claim 1, the method comprising the step of sintering a compact formed by pressure-molding of a mixed powder containing Fe powder and TiB2 powder, the compact being sintered by (i) applying pressure with use of a pressure member made of graphite and (ii) heating at the same time,
in the step of sintering, the compact being sintered such that:
by (i) applying a pressure of not less than 15 MPa and (ii) heating at a temperature of not less than 1323 K, (a) at least part of the TiB2 is decomposed and (b) a network-like matrix is formed, the network-like matrix containing Fe as a main component and also containing Ti;
the matrix contains αFe; and
TiC dispersed in the matrix is generated by a reaction between Ti and C, the Ti being derived from the TiB2, and the C being derived from the pressure member.
