A HIGH TEMPERATURE VACUUM FURNACE SYSTEM FOR FRACTURE TOUGHNESS TESTING, WHICH INVOLVES AN ACCESSORY CHAMBER FOR INSTALLING DISPLACEMENT MEASUREMENT SENSORS |
摘要 |
PURPOSE: A high temperature vacuum furnace system with an accessory chamber for installation displacement measurement sensors used in a fracture toughness test is provided to implement reliable and convenient measurement of high-temperature fracture toughness of a metal material by using a clip-on-gauge for room temperature in a high-temperature and high-vacuum conditions. CONSTITUTION: A high temperature vacuum furnace system used in a fracture toughness test comprises a vacuum furnace body(11), a heating element(12) for heating a specimen, a displacement sensor installation accessory chamber(13) which is attached to the vacuum furnace body to install displacement sensors, a corrugated pipe(14) which is connected to top and bottom flanges of the vacuum furnace body to keep the airtight seal during a test, an adapter(15) which transfers loads generated in the vacuum furnace body to the specimen, a grip(16) which is coupled with the specimen to place the specimen in the vacuum furnace body, a gauge attachment(17)which transfers displacement generated when a load is applied to the high-temperature specimen to displacement sensors, a vacuum port(18) which is connected to a vacuum pump installed outside the vacuum furnace body, and a vacuum feedthrough(19) which transfers electric signals generated by the sensors in the accessory chamber to an external signal processing device. |
