OBJECTIVE:

  • To impart knowledge on the structure, properties, treatment, testing and applications of metals and non-metallic materials so as to identify and select  suitable  materials  for various engineering

UNIT I  ALLOYS AND PHASE DIAGRAMS                                                                           

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

UNIT II  HEAT TREATMENT                                                                                                    

Definition – Full annealing, stress relief, recrystallisation and spheroidising – normalising, 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 and Induction hardening – Vacuum and Plasma hardening. .
