Abstract

The invention provides a phase-transition temperature tester and a testing method thereof. The phase-transition temperature tester comprises a container, a heating device, an image acquiring device, atemperature sensor and a processor, wherein the container is used for containing a tested sample; the heating device is used for heating the tested sample in the container; the image acquiring deviceis used for acquiring an image of the tested sample; the temperature sensor is connected with the container and is used for detecting the temperature change of the tested sample; and the processor iselectronically connected with the image acquiring device and the temperature sensor and is used for detecting the displacement change, caused by the heating, of the tested sample according to the acquired image and generating a temperature displacement curve of the tested sample according to the detected displacement change, and temperature change. According to the phase-transition temperature tester and the testing method, the non-contact measurement of the phase-transition temperature of nickel-titanium alloy is realized, nickel-titanium alloy brackets of any specification and shape can beaccurately tested, and the applicability is wide.

Description

technical field [0001] The invention relates to a phase change temperature tester, in particular to a non-contact phase change temperature tester for detecting the phase change temperature of a nickel-titanium alloy and a test method thereof. Background technique [0002] In existing practice, the method of manual judgment is usually used to test the phase transition temperature A of nickel-titanium alloy S and A F , but the accuracy of this test is not high and the workload is heavy. Therefore, in recent years, a device that can realize automatic detection of A F The contact phase change temperature tester is used to detect the shape change of nickel-titanium alloy with temperature change by contacting it. However, for millimeter-scale tiny nickel-titanium alloy stents, the contact phase change temperature tester has limitations, and there will be mechanical friction errors between the position sensor and the detected rod, making it difficult to accurately measure tiny n...
