JNTUH B.Tech 2nd Year 1 sem Metallurgy Material Technology (2-1) Physical Metallurgy Engineering R13.

JNTUH B.Tech 2nd year Physical Metallurgy gives you detail Physical Metallurgy Engineering R13 year subject. It will be help full you to understand you complete curriculum of the year.

Objective

The Prime objective of this course is to make the student understand the interrelation between microstructure and characteristics of Metals and Alloys. The course also critically focuses on the crystallography, phase transformations that occur in several ferrous and nonferrous metallurgical systems as a function of temperature and composition through phase equilibrium diagrams.

UNIT – I

Crystal structure  Crystallography: space lattice, unit cell, lattice parameter, coordination number, atomic radius, packing factor, density calculations. Miller’s indices. Relation between crystal structure and ductility. Solidification:  homogeneous and heterogeneous nucleation. Polymorphism.

UNIT – II

Microstructures  Grains and grain boundaries. ASTM Grain Size. Grain size dependence of strength. Strain  hardening, Recrystallization, and grain growth. Solid solutions – substitutional and interstitial solid solutions.

UNIT – III

Binary Phase diagrams  Construction. Isomorphous and eutectic systems-Specific examples: Cu-Ni, Pb-Sn, AlCu.  Structure evolution. Phase rule. Lever rule. Hume-Rothery rules. Importance of electron-to-atom ratio. Intermediate phases, Inter metallic compounds. Application of phase diagrams. Precipitation hardening.

Outcome

At the conclusion of this course, the student will be able to appreciate and establish the crystal structure of metals, structure-property correlation in metals, importance of phase equilibrium diagrams of ferrous (in particular Iron-Carbon System) and nonferrous metallurgical systems and their significance as a tool for alloy design. The student will also be able to determine the quantity of phases present, ASTM Grain Size, kinetics of solidification of alloys.
