Heat Treatment of Metals and Alloys Syllabus for B.Tech 5th sem is covered here. This gives the details about credits, number of hours and other details along with reference books for the course.
The detailed syllabus for Heat Treatment of Metals and Alloys B.Tech (R13) fifthsem is as follows
OBJECTIVES:
The course covers the fundamental aspects of the theory and practice of heat treatment of metals and alloys. It provides a comprehensive understanding of the various transformation reactions associated with the changes in microstructure and property that occur due to controlled heat treatment.
UNIT I : TRANSFORMATIONS IN STEELS [10 Hours]
Allotropic changes in Iron, Iron-Iron carbide equilibrium diagram – transformations on heating and cooling – influence of alloying elements – general principles of heat treatment of steels – isothermal and continuous cooling transformations in steels – Time-Temperature- Transformation curves (TTT diagrams), continuous cooling transformations – CCT-diagrams – effect of alloying additions on TTT diagrams, mechanism and kinetics of pearlitic, bainitic and martensitic transformations – precipitation hardening
UNIT II : HEAT TREATMENT PROCESSES [9 Hours]
Annealing- Types, Normalising, Hardening & Quenching –Mechanisms-hardenability studies – Jominy end-quench test, Grossman’s experiments, tempering – Hollomon & Jaffe tempering correlations, tempering – tempered brittleness – effects of alloying elements on tempering, austempering and martempering, precipitation hardening, thermomechanical treatment, intercritical heat treatment, polymer quenching, sub-zero treatment – cryogenic quenching, patenting
UNIT III : CASE HARDENING [9 Hours]
Introduction, carburisation – principle – carbon potential – mechanism application of Fick’s law – depth of carburisation and its control – methods of carburising – heat treatment after carburising– structure, properties and defects in carburising, nitriding – mechanism – retained austenite – Remedy- effect of microstructure – nitriding methods, ion-nitriding and nitro-carburising, boronising, chromising, cyaniding and carbonitriding, induction and flame hardening, Laser and Electron beam hardening and welding – principles – methods – operating variables, measurement of case depth
TOTAL: 45 PERIODS
