description A nondestructive variable-temperature testing apparatus for the mechanical properties of materials. The nondestructive variable-temperature testing apparatus comprises an external information and processing system and an integrated closed detection device, wherein the external information and processing system comprises: an oscilloscope (1) for displaying ultrasonic echo images; a pulse signal transceiver (2) for generating electrical pulse signals; and an ultrasonic transducer (11), which is a probe for transmitting ultrasonic waves and receiving echoes, and which computes the speed of transverse waves and longitudinal waves by selecting a waveform having a constant and stable period according to an echo image displayed by the oscilloscope (11); and the integrated closed detection device comprises: a housing portion for fixing the entire testing apparatus and providing a thermal insulation function; a platform portion for placing a test sample for testing and rotating the test sample; and a transmission port
