FY 1992 Research and development of ceramic gas turbines. Reliability demonstration tests for ceramic members; 1992 nendo ceramic gas turbine no kenkyu kaihatsu seika hokokusho. Ceramic buzai no shinraisei kakusho shiken

Abstract

The creep rupture demonstration testing methods and non-destructive testing technologies are investigated for ceramic members, to promote development of ceramic gas turbines (CGT's), and the FY 1992 results are reported. For creep rupture demonstration testing methods, 3 types of silicon nitride as the CGT rotor materials are tested for tensile creep rupture at a rated temperature level (1200 degrees C) in the operating atmosphere (in the air), and applicability of the Larson-Miller method to ceramic members is investigated. It is found that Larson-Miller index, determined for each test temperature, is useful for explaining the test results, and analysis of the data by the Larson-Miller method is applicable to prediction of creep rupture life for specific members. For the non-destructive testing technologies to be applied to CGT members, the studied items include determination of white X-ray absorption coefficient by the film method and optimization of X-ray photographing, and the good results are produced.
