A method for obtaining the brittle-plastic transition depth of two-phase composite materials

This invention discloses a method for obtaining the brittle-plastic transition depth of a two-phase composite material. The method involves using a metallographic microscope to capture a microscopic image of the scratch surface morphology. The locations of the first small pit and the first large pit in the scratch are determined from this image. Then, the distances from these two locations to the scratch incision point are measured using a measuring scale. The three-dimensional morphology of the scratch groove is obtained by photographing it using a white light interferometer. Based on the distances obtained from the measuring scale, the starting point (first small pit) and the ending point (first large pit) of the brittle-plastic transition zone are determined. The cross-sectional profile curve of the scratch at these locations is then captured, and the groove depth is measured. This invention combines the microscopic morphology captured by a microscope with the three-dimensional morphology obtained by white light interferometry to accurately determine the location and depth of the brittle-plastic transition in the material. This avoids interference from defects in the two-phase composite material itself or surface impurities and dust, effectively improving the accuracy of the test results.

PendingCN122329896APolymer sciencePhotopigment
This invention belongs to the field of polypropylene material production, specifically a device for testing the scratch resistance of polypropylene materials. It includes a testing platform and a scratching blade. The testing platform is equipped with an orientation adjustment component for controlling the displacement of the scratching blade, and includes an auxiliary component for observing the scratched area. The auxiliary component for observing the scratched area includes a sponge roller, a rigid tube, and a pigment tank. The rigid tube is located above the sponge roller, and multiple nozzles aligned with the surface of the sponge roller are located at the bottom of the rigid tube. The pigment tank is fixedly connected to one side of the upper surface of the testing platform, and a pigment pump is fixedly connected to one side of the outer wall of the pigment tank. The inlet end of the pigment pump communicates with the inner cavity of the pigment tank. This invention allows pigment to be applied to the surface of a material after the scratching blade has scratched it. Because the scratches are concave, the pigment only adheres to the area outside the scratches, thus creating a clear contrast between the scratches and the rest of the material surface, making it easy for personnel to distinguish the width and depth variations of the scratches.
