概要 （英文）

THIS REPORT DESCRIBES A UNIQUE HIGH-TEMPERATURE FATIGUE CREEP TESTING SYSTEM DEVELOPED RECENTLY FOR MICROSCOPIC OBSERVATION OF CREEP-FATIGUE DAMAGE. IN THIS NEW SYSTEM,A CLOSED-LOOP,ELECTRO-HYDRAULIC SERVO-CONTROLLED MACHINE WAS COMBINED WITH A SCANNING ELECTRON MICROSCOPE(SEM). BY USING THIS SYSTEM,CREEP-FATIGUE TESTS UP TO 1000 DEGREE CAN BE CARRIED OUT UNDER INSITU SEM CLEAR OBSERVATION UP TO 5000-TIMES MAGNIFICATION. THE RESULTS OF CREEP-FATIGUE TESTS ON TYPE 304 STAINLESS STEEL AND NI-BASE SUPERALLOY(ASTROLOY)ARE ALSO SHOWN IN THIS REPORT.
