Delta region of iron iron carbide diagram | Micro-structure of hypo eutectoid steel | Slow cooling

Microstructure of hypoeutectoid steel (II ) Hypo and hyper eutectoid steel formation Development of microstructure Mechanical properties Delta region reactions Slow cooling of steel Slow cooling of hyper eutectoid reactions 1. (a) Schematically sketch simple isomorphousand eutectic phase diagrams.(b) On these diagrams label the various phaseregions.(c) Label liquidus, solidus, and solvus lines.2. Given a binary phase diagram, the compositionof an alloy, its temperature, and assuming thatthe alloy is at equilibrium, determine(a) what phase(s) is (are) present,(b) the composition(s) of the phase(s), and(c) the mass fraction(s) of the phase(s).3. For some given binary phase diagram, do thefollowing:(a) locate the temperatures and compositions ofall eutectic, eutectoid, peritectic, and congruent phase transformations; and(b) write reactions for all these transformationsfor either heating or cooling.4. Given the composition of an iron–carbon alloycontaining between 0.022 wt% C and 2.14 wt% C,be able to(a) specify whether the alloy is hypoeutectoidor hypereutectoid,(b) name the proeutectoid phase,(c) compute the mass fractions of proeutectoidphase and pearlite, and(d) make a schematic diagram of the microstructure at a temperature just below theeutectoid. #Professional_Expert_Miscellaneous #Engineering_Materials
