**Very important questions are bolded and may be asked based on this topic
PART-C
1.Compulsory Questions {a case study where the student will have to read and analyse the subject }
mostly asked from unit 4and 5(OR) a situation given and you have to answer on your own
don't waste my hardwork and valuable time
As Engineer i think you know how to respect another
Share it as link alone . don't share it as screenshot or any text material if u found this anywhere kindly report me . #Admin WhatsAppContact uS
*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 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. .
UNIT III FERROUS AND NON-FERROUS METALS
Effect of alloying additions on steel- a and ß stabilisers– stainless and tool steels — HSLA, Maraging steels — Cast Iron — Grey, white, malleable, spheroidal — alloy cast irons, Copper and copper alloys — Brass, Bronze and Cupronickel — Aluminium and Al-Cu — precipitation strengthening treatment — Bearing alloys, Mg-alloys, Ni-based super alloys and Titanium alloys.
UNIT IV NON-METALLIC MATERIALS
Polymers — types of polymer, commodity and engineering polymers — Properties and applications of various thermosetting and thermoplastic polymers (PP, PS, PVC, PMMA, PET,PC, PA, ABS, PI, PAI, PPO, PPS, PEEK, PTFE, Polymers — Urea and Phenol formaldehydes)- Engineering Ceramics — Properties and applications of Al2O3, SiC, Si3N4, PSZ and SIALON –Composites-Classifications- Metal Matrix and FRP — Applications of Composites.
UNIT V MECHANICAL PROPERTIES AND DEFORMATION MECHANISMS
Mechanisms of plastic deformation, slip and twinning — Types of fracture — Testing of materials under tension, compression and shear loads — Hardness tests (Brinell, Vickers and Rockwell), hardness tests, Impact test lzod and charpy, fatigue and creep failure mechanisms.
