JNTUK B.Tech Heat Treatment Technology gives you detail information of Heat Treatment Technology R13 syllabus It will be help full to understand you complete curriculum of the year.
Course Objective: This subject deals with Principles of heat treatment of steels, Alloy steels and some non ferrous alloys and different heat treatment methods.
UNIT-I : Learning Objective: This unit deals with principles of heat treatment, and different hardenability methods.
Principles Of Heat Treatment: Austenitic Transformation, Pearlitic Transformation, Bainitic Transformation, Martensitic Transformation, Annealing, Normalizing, Hardening, mechanism of heat removal during quenching, quenching media, size and mass effect, hardenability, tempering, austempering, manufacturing, deep freezing. Heat treatment furnaces and their design, atmosphere control vacuum heat treatment etc
UNIT-II : Learning Objective: To learn about different surface hardening methods. Surface heat treatment, carburizing, cyaniding, flame and induction hardening, residual stresses, deep freezing, thermo mechanical treatments: HTMT, LTMT, Ausforming, Isoforming, Cryoformy.
UNIT-III : Learning Objective: This topic throws light on TTT Curves and effect of alloying elements on Fe-Fe3C system.
Effect Of Alloy Elements: Purpose of alloying, effect of alloying elements on ferrite, cementite, Fe- Fe3C system, tempering and TTT Curves.
UNIT-IV : Learning Objective: This topic explain heat treatment of various types of tool and die steels.
Alloy Steels: Structural and constructional steels, maraging steels, tool and die steels. Corrosion and heat resistant steels, Hadfield steels, magnetic steels and alloys, free machining steels.
UNIT-V : Learning Objective: To understand the principles of heat treatment of various cast irons.
Cast Irons: White cast iron, grey cast iron, spheroidal graphite iron, malleable cast iron, alloy cast iron.
UNIT-VI : Learning Objective: To understand the principles of heat treatment of various non ferrous alloys.
Non-Ferrous Metals And Alloys: Precipitation hardening, aging treatment, study of copper and its alloys, aluminum and its alloys, nickel and its alloys.
(Assessment: The student should be evaluated based on the assignments and objective tests. The student’s analytical abilities (with special focus on academically weak students) should be tested periodically in classes by giving problems). Emphasis should be given by conducting tutorial classes at the end of each unit.
