GENERAL INFORMATION ON METALLOGRAPHIC ANALYSIS
Keywords:
Macroanalysis, microanalysis, X-ray analysis, large defects, cracks, pits, gas bubbles, fracture, brittle fracture, fibrous fracture, granular fracture, brittle fracture, granular fracture.Abstract
In this article, the macrostructure of alloys is studied by the methods of metallographic analysis with the help of an ordinary eye and an optical magnifier. Today, the structure of metals and alloys is studied by macro and microanalysis, X-ray, as well as defectoscopy (X-ray, magnetic, ultrasound and other methods). The macrostructure, that is, the visible structure, is studied with the naked eye or with the help of an optical magnifying glass. Such large defects, i.e., cracks, depressions, gas bubbles, etc., as well as the uneven distribution of impurities in the metal, are determined.
