Iron and Steel Microstructures Overview

This document provides an overview of typical iron metal structures, including pure iron, steel, and cast iron, along with detailed descriptions of microstructures such as ferrite, cementite, pearlite, austenite, martensite, and sorbite. It explains how these structures influence mechanical properties like strength, toughness, and ductility, and highlights the use of digital microscopes for observation and grain size analysis.
