Design methodologies were evolved in the 70s, incorporating the principles of fracture mechanics and the statistical variation and time dependence of strength. These have been used successfully to predict the engineering behaviour of ceramics in the lower range of temperature. In spite of the above, and the underlying thermodynamic arguments for operations at higher temperatures, there has been a disappointing uptake of these materials in industry for high temperature usc. Most of the successful applications are for low to moderate temperatures such as seals and bearings, and metal cutting and shaping. The reasons have been very well documented and include: • Poor predictability and reliability at high temperature. • High costs relati | | 出版日期 | Book 1991 | | 关键词 | cement; ceramics; composite; composite materials; mechanical properties | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-011-3678-5 | | isbn_ebook | 978-94-011-3678-5 | | copyright | ECSC, EEC, EAEC, Brussels and Luxembourg 1991 |
