Welcome to 'Basics of Materials Engineering' course ! • This lecture provides a detailed explanation of constructing and interpreting isothermal transformation (TTT) diagrams. It outlines the experimental steps involved in generating TTT diagrams, emphasizing the need for rapid cooling and holding at a constant subcritical temperature. It discusses the different microstructures obtained at various temperatures and times on the TTT diagram, including coarse pearlite, fine pearlite, bainite, and martensite. It introduces continuous cooling transformation (CCT) diagrams, which represent transformations under continuous cooling conditions, as opposed to isothermal holding. It contrasts the CCT diagram with the TTT diagram. • NPTEL Courses permit certifications that can be used for Course Credits in Indian Universities as per the UGC and AICTE notifications. • To understand various certification options for this course, please visit https://nptel.ac.in/courses/112106293 • #TTTDiagrams #ContinuousCoolingTransformation #CCTDiagrams #MicrostructureControl #EutectoidSteel
