Today we are discussing for Material Science Syllabus – AKTU Btech 2021-22 syllabus.
UNIT-1: PHASE DIAGRAMS Solid solutions – Hume Rothery’s rules – the phase rule – single component , system – one-component system of iron – binary phase diagrams -isomorphous systems – the tie-line rule – the lever rule – application to isomorphous system – eutectic phase diagram – peritectie phase diagram – other invariant reactions – free energy composition curves for binary systems – microstructural change during cooling. UNIT-2 : FERROUS ALLOYS The iron -carbon equilibrium diagram – phases, invariant reactions -microstructure of slowly cooled steels – eutectoid steel, hypo and hypereutectoid steels – effect of alloying elements on the Fe-C system – diffusion in solids – Fick’s laws – phase transformations – T-T-T-diagram for eutectoid steel – pearlitic, baintic and martensitic transformations tempering of martensite – steels – stainless steels – cast irons. UNIT-3 : MECHANICAL PROPERTIES Tensile test – plastic deformation mechanisms – slip and twinning – role of dislocations in slip – strengthening methods – strain hardening – refinement of the grain size – solid solution strengthening – precipitation hardening – creep resistance – creep curves – mechanisms of creep – creep-resistant materials – fracture – the Griffith criterion – critical stress intensity factor and its determination – fatigue failure – fatigue tests – methods of increasing fatigue life – hardness -Rockwell and Brinell hardness – Knoop and Vickers microhardness.
