Stress-Rupture Strength of Polycrystalline Oxide Ceramic up to 1600°C

Stress-Rupture Strength of Polycrystalline Oxide Ceramic up to 1600°C Experimental data are given for stress-rupture strength (time and deformation to failure) determination for densely-sintered oxide ceramic with four-point bending in the range 1400 – 1550°C (somewhat above the brittle-ductile transition temperature) and with loads up to 60 MPa (close to the ultimate strength). It is shown that elementary mechanical deformation over the whole range of specimen ductile behavior is diffusion-viscous flow with different forms, i.e., dislocation and crystal boundary diffusion movement. Data obtained agree with the suggestion that for transition from ceramic brittle to ductile failure occurrence of some critical vacancy concentration within it is necessary. Independent of ceramic crystal size and test conditions the secondary creep rate and time to failure are constant, and deformation to failure is also constant.
