| 摘要 | Creep and stress relaxation of Ti3AlC2 were investigated using three-point bending tests at 800-1200degreesC under various load levels. The results show that the creep rate significantly increases with increasing temperature in the rang of 1000-1200degreesC. Subcritical crack growth during the creep process was found to be the main failure mechanism, i.e., the stress intensity factor increases with the creep-induced crack growth and results in the ultimate fracture. The lower limit of stress relaxation was considered as the threshold value of zero-creep stresses, and the ratio of the threshold stress to the applied stress was defined to be a parameter of creep resistance for estimating deformation behavior at high temperature. SEM examination confirmed that the creep failure in Ti3AlC2 was governed by such a damage evolution: cavitation --> crack initiation --> crack extension --> fracture. |
