Answer #1

Answer!: Austenite (0.7 wt%C) and liquid (1.7 wt%C)

The alloy 1wt%C at 1400 o exists as (Austinite and Liquid phase mixture). The composition Carbon in Austinite phase is represented by point B, 0.07wt% C and the composition while the composition of Carbon in liquid phase is represented by point A, 1.7wt%C.
