316H不锈钢中析出相成分及结构的研究

Stainless steel is one of the most widely used alloys in daily life and production. 316H stainless steel has attracted wide attention because of its excellent corrosion resistance, high temperature resistance and good mechanical properties. It is very important to clarify the relationship between mechanical properties and microstructure to guide the further optimization and improvement of the properties of the stainless steel. Therefore, this paper take the precipitated phase in 316H stainless steel as the research object, use advanced electron microscopy to determine its morphology, structure, composition, distribution and other information, and explore the influence mechanism of precipitation on the mechanical properties of the stainless steel, to provide reference for the better application of this stainless steel.????
