Fine ceramics (advanced ceramics, advanced technical ceramics). Determination of elastic modulus of ceramics at high temperature by thin wall C-ring method
| Published By | Publication Date | Number of Pages |
| BSI | 2020 | 18 |
This document specifies the determination of elastic modulus of ceramics at high temperatures up to 2 100 °C by using the thin wall relative C-ring method. Procedures for test piece preparation, test modes, heat rate, load rates, data collection and reporting are given.
This document applies primarily to ceramic materials including monolithic fine ceramics, refractory materials, whisker and particulate-reinforced ceramic composites. This method is not applicable to super plastic ceramics or ceramics with high creep rate. This test method can be used for material research, quality control and characterization and design data generation purposes.
