ME25C08:

Metallurgy and Materials Science

 

Course Objective:

This course provides knowledge on phase diagrams, ferrous and non-ferrous materials, heat treatment processes, polymers, ceramics, composites, and mechanical behavior of engineering materials. It enables students to understand material selection, microstructure-property relationships, testing methods, and modern materials used in engineering applications.

 

Constitution of Alloys and Phase Diagrams: Constitution of alloys – Solid solutions, substitutional and interstitial – phase diagrams, Isomorphous, eutectic, eutectoid, peritectic, and peritectoid reactions, Iron – Iron carbide equilibrium diagram. Classification of steel and cast-Iron microstructure, properties and application.

Activity: Study of phase diagrams and microstructures.

 

Heat Treatment: Definition – Full annealing, stress relief, recrystallisation and spheroidising – normalizing, hardening and tempering of steel. Isothermal transformation diagrams – cooling curves superimposed on I.T. diagram – continuous cooling Transformation (CCT) diagram – Austempering, Martempering – Hardenability, Jominy end quench test -case hardening, carburizing, Nitriding, cyaniding, carbonitriding – Flame and Induction hardening – Vacuum and Plasma hardening – Thermo-mechanical treatments- elementary ideas on sintering.

Activity: Demonstration of heat treatment and hardenability test.

 

Ferrous and Non-Ferrous Metals: Effect of alloying additions on steel (Mn, Si, Cr, Mo, Ni, V,Ti& W) – stainless and tool steels – HSLA - Maraging steels – Grey, white, malleable, spheroidal – alloy cast irons, Copper and its alloys – Brass, Bronze and Cupronickel – Aluminium and its alloys; Al-Cu – precipitation strengthening treatment – Titanium alloys, Mg-alloys, Ni-based super alloys – shape memory alloys- Properties and Applications-overview of materials standards.

Activity: Alloy identification and material selection exercise.

 

Non-Metallic Materials: Polymers – types of polymers, commodity and engineering polymers – Properties and applications of PE, PP, PS, PVC, PMMA, PET, PC, PA, ABS, PAI, PPO, PPS, PEEK, PTFE, Thermoset polymers – Urea and Phenol formaldehydes – Nylon, Engineering Ceramics – Properties and applications of Al2O3, SiC, Si3N4, PSZ and SIALON – intermetallics- Composites-Matrix and reinforcement Materials- applications of Composites - Nano composites.

Activity: Classification of polymers, ceramics, and composites.

Mechanical Properties and Deformation Mechanisms: Mechanisms of plastic deformation, slip and twinning – Types of fracture – fracture mechanics- Griffith’s theory- Testing of materials under tension, compression and shear loads – Hardness tests (Brinell, Vickers and Rockwell), Micro and nano-hardness tests, Impact test lzod and charpy, fatigue and creep failure mechanisms.

Activity: Demonstration of tensile, hardness, and impact tests.
