| 中文摘要 | We report here experimental results of yield strength and stress relaxation measurements of transparent MgAl(2)O(4) nano-ceramics at high pressure and temperature. During compression at ambient temperature, the differential strain deduced from peak broadening increased significantly with pressure up to 2 GPa, with no clear indication of strain saturation. However, by then, warming the sample above 400A degrees C under 4 GPa, stress relaxation was obviously observed, and all subsequent plastic deformation cycles are characterized again by peak broadening. Our results reveal a remarkable reduction in yield strength as the sintering temperature increases from 400 to 900A degrees C. The low temperature for the onset of stress relaxation has attracted attention regarding the performance of transparent MgAl(2)O(4) nano-ceramics as an engineering material. |
