JNTUK B.Tech Physical Metallurgy gives you detail information of Physical Metallurgy R13 syllabus It will be help full to understand you complete curriculum of the year.
Course Objective: It is an introductory course for the students of Metallurgical Engineering and the subject deals with the fundamental concepts about the various types of microscopes, crystsal structures, phase diagrams and their applications.
UNIT – I : (Learning objective: To understand the theory, construction and working details of Metallurgical microscopes.)
Microscopy; Metallurgical Microscope, principles and construction, types of objectives and eyepieces, common defects of lenses, electron Microscope.
UNIT – II : (Learning objective: To understand the basic crystal structures of various materials which forms the basis for the subsequent study of properties of materials.) Structure of Metals, Hume-Rothery’s classification of metals, metallic bond-crystal structure of metals, coordination number, relationship between lattice parameter and atomic radius, packing factor and density calculations, interstitials, polymorphism, plane and directional indices, transformation of indices.
UNIT – III : Learning objective: To understand the constitution and necessity of alloy formation. To study the associated Hume Rothery rules for the formation of alloys.) Constitution of Alloys: Necessity of alloying; types of solid solutions, Hume-Rotherys rules. Intermediate alloy phases, electro-chemical compounds, size factor, compounds and electron phases.
UNIT – IV : (Learning objective: The chapter outlines the various experimental methods of construction of phase diagrams. The unit also outlines the solidification behavior of materials during cooling.)
Equilibrium Diagrams: Experimental methods for construction of equilibrium diagrams, Isomorphous alloy systems, eutectic and partial eutectic systems.
Solidification: Types of Nucleation, determination of the size of critical nucleus, equilibrium cooling and heating of alloys, lever rule, coring, miscibility gaps. Simple problems using lever rule.
UNIT – V (Learning objective: The unit intended to describe various phase diagrams and phase transformations) Transformation in solid state, allotropy, order-disorder transformation, eutectoid, peritectoid reactions and complex phase diagrams, relation between equilibrium diagrams and physical properties of alloys. Study of important binary phase diagrams like Fe-Fe3 C, Cu-Zn, Cu-Sn, and Al-Cu.
UNIT – VI : (Learning objectives: To provide the detailed explanation of phase transformations in steels and to understand the importance of isothermal diagrams) Phase transformations in steels pearlitic, martensitic and bainitic transformations cooling curves. Isothermal transformation diagrams, transformations on continuous cooling.
(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 with respect to Phase diagrams and others. Unit tests are to be conducted at the end of each unit).
