Information × Registration Number 0299U000551, 0196U015050 , R & D reports Title Development of a new procedure for predicting the long-term operational life of heat-resistant metallic materials used in engineering and power industries, transport facilities, etc., which is as long as 300 000 hours under high-temperature loading. popup.stage_title Head Kryvenyuk V.V., Registration Date 19-04-1999 Organization Institute for problems of strength NASci of Ukraine popup.description2 The prediction of the long-term strength of metallic materials of 300000 hrs and above was studied. A systematic analysis of a considerable amount of data on the tests of a duration of 100000 hrs and above has been first made. Based on the results obtained, the method of base diagrams has been refined. Considerable potentialities have been found to increase the accuracy and reliability of the prediction based on the empirical investigations and, in particular, on the principle of basic relations applied. The utility of the above principle and method is shown for various conditions of loading. The advantage of the refined method of base diagrams as compared to the best world-wide analogs is substantiated. The method is recommended for heat-resistant steels used in the power engineering and in the preparation of the standard document for assessing and predicting the state of steam turbines Product Description popup.authors popup.nrat_date 2020-04-03 Close
