| description | The invention relates to the technical field of steel and iron material microstructure inspection, in particular to a cold-rolled deep drawing steel microstructure observation sample preparation method. The sample preparation method for observing the microstructure of the cold-rolled deep-drawing steel comprises the steps of cutting a cold-rolled deep-drawing steel sample, inlaying, grinding step by step, polishing, corroding a to-be-detected surface of the sample and observing, a cold inlaying method with denture powder and denture water as inlaying materials is adopted for inlaying, and an alcohol mixed solution of 5% glacial acetic acid and 5% nitric acid is adopted as a corrosive liquid for corrosion. According to the method provided by the invention, ferrite grains presented in a vision field in a microstructure picture obtained by the method have clear grain boundaries and complete grains, and the morphology, the number and the size of the grains can be clearly observed.
