| description | The invention relates to a method for detecting the cold brittleness transition temperature of a metal material, and belongs to the field of material performance test. The method comprises the following steps: taking a metal material to be detected, making a sample from the metal material to be tested, gradually reducing the temperature of the sample in a low temperature container, measuring the resonance frequency of the sample at different temperature points, drawing a temperature-resonance frequency curve map, and obtaining the cold brittleness transition temperature of the metal material, which is the temperature corresponding to an inflection point in the temperature-resonance frequency curve map or to a gradient change point. The method is suitable for measuring the cold brittleness transition temperature of the metal material, provides a brand new measurement way for cold brittleness measurement, and has the characteristics of good test accuracy and convenience in test.
