BASICS OF ENGINEERING METALLURGY

 L T P C

3003

OBJECTIVE:
To introduce the basic concepts of metallurgy, metallurgical structures and mechanical properties, testing of metals

UNIT I

CONSTITUTION OF ALLOYS

9

Crystal structure – BCC, FCC and HCP structure – unit cell – crystallographic planes and directions, miller indices – crystal imperfection, point, line, planner and volume defects – Grain size, ASTM grain size number. Constitution of alloys – Solid solutions, substitutional and interstitial Solid Solutions.

UNIT II

PHASE DIAGRAMS

9

Phase diagrams, isomorphous, eutectic, peritectic, eutectoid and peritectoid reactions, Iron – Iron carbide and Iron – Carbide & Iron Graphite equilibrium diagram. Classification of steel and cast iron - microstructures of Steels & Cast irons - properties and application.


UNIT III

HEAT TREATMENT

9

Defintion – Full annealing, stress relief, recrystallisation and spheroidizing – normalizing, hardening and tempering of steel, Isothermal transformation diagrams – cooling curves superimposed on I.T. diagram CCR – Hardenability, Jominy end quench test – Austempering martempering – case hardening, carburizing, nitriding cyaniding, carbonitriding – Flame, Induction Laser and Electron beam and plasma phase hardening – Special and Duplex surface hardening processes.

UNIT IV

FERROUS and NON FERROUS METALS

9

Effect of alloying additions on steel (Mn, Si, Cr, Mo, V Ti & W) – stainless and tool steels – HSLA – maraging steels – Gray, white, malleable spheroidal, graphite, alloy cast irons, Aluminium and Copper Alloys, AI-Cu – precipitation strengthening treatment. Shape memory alloys.

UNIT V

MECHANICAL PROPERTIES AND TESTING

9

Mechanism of plastic deformation, slip and twinning – Types of fracture – Testing of materials under tension, compression and shear loads – hardness tests (Brinell, Vickers and Rockwell) micro and nano hardness test impact test, Izod and charpy, fatigue and creep mechanisms.

TOTAL: 45 PERIODS

OUTCOMES: Upon the completion of the course, students will be able to
1. Analyze the role of various constituents and phases in metals and alloys.
2. Understand the importance of heat treatment in ferrous and non ferrous metals and alloys.
3. Categorize the ferrous and nonferrous metals and alloys based on the constituents.
4. Understand the procedure involved in mechanical testing of metals and alloys.
