Description

technical field [0001] The invention relates to a method for testing the mechanical properties of brazed joints, which relates to the field of material mechanical properties experiments, in particular to a method for testing the mechanical properties of brazed joints. Background technique [0002] Tensile test refers to an experimental method for determining the properties of materials under axial tensile load. The data obtained from the tensile test can determine the elastic limit, elongation, elastic modulus, proportional limit, area reduction, tensile strength, yield point, yield strength and other tensile performance indicators of the material. It can study the macroscopic mechanical behavior of the sample, but to study the mechanical properties of micro-scale materials, such as brazed joints, the ordinary tensile test is far from meeting the experimental requirements. When studying the mechanical properties of materials such as brazed joints, we need Real-time observat...

The data obtained from the tensile test can determine the elastic limit, elongation, elastic modulus, proportional limit, area reduction, tensile strength, yield point, yield strength and other tensile performance indicators of the material. It can study the macroscopic mechanical behavior of the sample, but to study the mechanical properties of micro-scale materials, such as brazed joints, the ordinary tensile test is far from meeting the experimental requirements. When studying the mechanical properties of materials such as brazed joints, we need Real-time observation of the microscopic behavior of the entire stretching process of the material, which requires the use of in-situ stretching experiments to obtain the microscopic morphology changes of the material to study the mechanical behavior of the material
