| DESCRIPTION | Objectives This course covers the basic topics in metallurgy, giving the student the tools to work with and understand metallurgical processes and concepts. The effect of heating and alloying on metals is reviewed. Equilibrium and non-equilibrium states are compared. Topics include: Syllabus - Alloying. Purpose of alloying. Examples of alloying on the properties of metals. The solid solution, interstitial and substitutional solid solutions. Solubility, liquid-metal mixtures, complete solubility, complete insolubility and partial solubility. Solubility limit. - Equilibrium Phase Diagrams. The equilibrium state. Construction of a simple phase diagram. Different types of phase diagrams. The eutectic and peritectic transformations. The eutectoid and peritectoid transformations. Compound formation and intermetallics. The Gibbs Phase Rule. - Fe/Fe3C iron carbon diagram. Impurities in steel. Effect of Mn, Si, SP. Effect of alloying elements in the polymorphic transformation temperature. Stable carbide forming elements. Effects of alloying elements on grain growth - displacement of eutectoid point by alloying elements. Retardation of transformation rates. - The Heat-Treatment of Metals. Annealing, normalizing, hardening, tempering etc. Microstructural changes during heat-treatment. Development of TTT diagrams. The Joining Test, CCT Diagrams. Effect of alloying on the TTT diagram. Laboratory Work - Joining test - assessment of the hardenability of a steel - Heat treatment of medium carbon steel - structure/properties. Reference Texts - Higgins R.A., Engineering Metallurgy (I), (Hodder & Stoughton). - Smallman R.E., Modern Physical Metallurgy, (Butterwoth) |
