IN718C alloy and MC carbide reinforced IN718C composites (MC/IN718C) were prepared by casting. Creep behaviors of the two materials were studied. The steady-state creep rate of the MC/IN718C composite at 704 °C under 620 MPa was reduced by an order of magnitude. The higher creep resistance for the MC/IN718C composite was not caused by the increase in the stress exponent or the creep activation energy. Based on the quantitative research of load partitioning in the MC/IN781C composite by usingin situsynchrotron high energy X-ray diffraction under tensile loading, it was found the load bearing effect of the MC particles played an important role in the creep resistance improvement of MC/IN718C composite, which reduced the stress on the matrix, slowed down the creep of the matrix, and delayed the failure of the MC/IN718C composite.
