This textbook provides a comprehensive yet accessible introduction to numerical calculations in Metallurgical Engineering. It covers a broad spectrum of subjects—including metallurgical thermodynamics and kinetics, physical metallurgy, heat treatment, transport phenomena, X-ray diffraction, corrosion engineering, metallography, materials science, mechanical behaviour of materials, mechanical metallurgy, metal casting, solidification, manufacturing processes, and mineral processing. The book offers 50 practice sets, each containing 50 fully solved numerical problems. These exercises are developed using both real scientific data from actual materials and carefully programmed hypothetical data generated through random number techniques, ensuring diverse and realistic practice. Designed to meet the syllabus requirements of universities and institutions offering Metallurgical Engineering programs, the book helps learners apply mathematical principles to deepen their understanding of metallurgical phenomena. It also serves as a valuable self-study companion for diploma, undergraduate, and postgraduate students seeking to strengthen their numerical and conceptual foundations in metallurgy.
