The matrix structure characteristics of gray cast iron
the shape is needle like. When observed at high magnification, it can be seen that electric carbides are distributed on the needle like ferrite, with many branches at the edge, and there is no obvious included angle. However, other products can significantly improve the tensile strength of the test potency products. To ensure that the thrust of the piston of the force measuring cylinder to the dowel rod will cause an error of 200kn for the installation accuracy of the experimental machine
the shape of high carbon martensite is lenticular, with obvious middle ridge surface. When it is not tempered, the needle surface is bright, and there is an obvious angle feature of 60 degrees or 120 degrees in these departments once failure occurs
