ON THE STRAIN RATE SENSITIVITY INDEX AND GRAIN BOUNDARY GLASSY PHASE OF SUPERPLASTIC 3T-TZP
3Y—TZP陶瓷超塑性应变速率敏感性指数及晶界玻璃相

The influence of true strain, temperature and the testing technique on the value of strain rate sensitivity index m of superplastic 3% (in mol. ) yttria stabilized tetragonal zirconia ploycrystal (3Y-TZP) has been investigated. The results indicate that m
