Abstract

In this paper we report on the tensile creep behavior of fine-grained (3-5um) Ti3SiC2 in the 1000 C to 1200 C temperature, T, range and 10 MPa to 100 MPa stress s, range. The creep behavior is characterized by three regimes; a primary, a secondary or quasi-steady state and a tertiary. Interrupted creep tests show that volume-conserving plastic deformation is the dominant source of strain during secondary creep regime, while cavities and microcracks are responsible for the acceleration of the creep rate during tertiary creep regime.
