A steel sample with 1.5 wt.% carbon (no other alloying elements present) is slowly cooled from 1100°C to just below the eutectoid temperature (723°C. A part of...

In the Fe-Fe3C phase diagram, the eutectoid composition is 0.8 weight % of carbon at 725 °C. The maximum solubility of carbon in α-ferrite phase is 0.025 weight...

In the phase diagram shown in the figure, four samples of the same composition are heated to temperatures marked by a, b, c and d. At which temperature will a s...
