Features of microscopic and macroscopic analysis of 35HGSL steel

Abstract

Abstract Foundry steels are widely used in modern engineering today. But it is foundry steels that have the greatest number of defects, which can be detected by macro-and microanalysis. In addition, with the help of these studies, you can get an idea about the General structure of the metal and the presence of certain specific defects in it – stone-like and naphthalene fractures. Using microanalysis methods, it is also possible to evaluate the properties of multiphase alloys and cast iron, for which there are special scales that classify graphite and phosphide eutectic by shape and quantity. The article describes the features of conducting these studies using optical microscopy.
