Ultrasonic test method and device for high-temperature elasticity modulus

The invention discloses an ultrasonic test method and device for a high-temperature elasticity modulus. The ultrasonic test device comprises a heating furnace for placing a sample, a vacuum pump for vacuumizing the heating furnace, a transducer for acoustic emission and receiving, a water cooler for cooling down the transducer, a high-pressure argon cylinder for providing the heating furnace withan inert gas and a heating temperature control system, wherein the sample is rod-like; the whole upper section of the sample is located in the heating furnace; the lower section of the sample extendsout of the heating furnace; the part outside the heating furnace is clung to the transducer; a small groove for placing a temperature measuring thermocouple is formed in the outer surface of the middle of the upper section of the sample; a temperature signal measured by the thermocouple is sent to the heating temperature control system outside the heating furnace; the vacuum pump is connected withthe heating furnace throug
