The primary goal of ASTM E562-19 is to offer a standardized, unbiased, and simple procedure for quantifying microstructural features. While automated image analysis is covered under ASTM E1245 , E562 remains a critical benchmark for manual verification and research.
Understanding the volume fraction is vital because the distribution and quantity of phases directly influence a material's . For instance, in "linepipe steels," it is used to precisely estimate pearlite phase fractions, while in industrial quality assurance, it validates alloy processing optimization.
