Microsoft Word - Metallography Lab Manual

This laboratory manual serves as a comprehensive guide for B. Tech students in their second year, specifically during the third semester, detailing essential safety protocols and experimental procedures in physical metallurgy. The objective is to equip students with practical skills in metallographic techniques, enabling them to prepare and examine various metals and alloys under a microscope. The methodology includes hands-on activities such as studying the metallurgical microscope, preparing metallographic samples, and interpreting microstructures of both heat-treated steels and non-ferrous metals. Students are instructed to conduct microscopic examinations and report their findings in a structured format, focusing on significant features and magnifications relevant to the samples analyzed. Results from these activities are expected to deepen students' understanding of metallurgical principles through identification and sketching of microstructures. The emphasis on safety in the lab underscores the importance of following guidelines to maintain a secure working environment. This approach not only enhances students' knowledge but also promotes best practices in laboratory settings.
