HIGH-TEMPERATURE FATIGUE TEST METHOD CAPABLE OF ACCURATE TEMPERATURE CONTROL AND MEASUREMENT USING SMALL-SIZED FURNACE

摘要

PROBLEM TO BE SOLVED: To retain uniformity of a temperature distribution on a parallel part of a fatigue test piece regardless of the size of the fatigue test piece, and to acquire data having high reliability, in a high-temperature fatigue test using a small-sized furnace. SOLUTION: A heating temperature in the furnace 5 is measured by a thermocouple 10 formed by spot-welding flatly-processed metals of different kinds on fatigue test piece shoulder parts 1 on both upper and lower sides, and simultaneously a furnace output is controlled.
