Abstract
The high temperature creep behaviors of Cr 3C 2 composite were investigated under compressive and bending creep. The stress exponent and activation energy of Cr 3C 2 composite were obtained at 1000 and 1050 °C. Assuming different tensile and compressive responses in a ceramic material, bending creep responses of Cr 3C 2 composite were analyzed numerically. The numerical analysis showed that the stress state at the cross-section of a crept sample was redistributed nonlinearly and the neutral axis moved toward the compressive region as the applied stress increased during bending creep.
