1. A method of producing an α-Fe—SiC composite, comprising:
an alloy preparation step comprising preparing an alloy which is a solid solution containing α-Fe as a solvent and at least one type of α-phase stabilizing element as a solute;
a first mixing step comprising mixing at least one type of α-phase stabilizing element in powder form and SiC to prepare a first mixture;
a second mixing step comprising mixing the alloy and the first mixture to prepare a second mixture, the second mixture prepared in the second mixing step containing the at least one type of α-phase stabilizing element in an amount of not less than 15.0 at. % and not more than 20 at. % relative to Fe contained in the α-Fe—SiC composite, the second mixture containing, as at least part of the at least one type of α-phase stabilizing element, Ti in an amount of not less than 8.0 at. % relative to Fe contained in the α-Fe—SiC composite; and
a sintering step comprising sintering the second mixture.
