Contact uS for more updates
*These questions are expected for the exams This may or may not be asked for exams All the best.... from admin Santhosh
Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates ~$tuff$£ctorSYllabuSUNIT I 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.
UNIT II 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.
UNIT III FERROUS AND NON-FERROUS METALS
