a- Schematize the equilibrium diagram for the A-B system, based on the following data:Melting point of A= 700ºC; Melting point of B = 1,000ºC; eutectic temperature = 500ºC; Composition of the liquid in equilibrium at eutectic temperature = 30%A and 70%B; Solubility at 500ºC, B at A = 15% and A at B = 20%. b- What is the type of steel and the carbon content according to the ABNT classification for the following steels: ABNT 1040, ABNT 1130, ABNT 5160 e ABNT 8620. c- Why is the Fe-Fe3C phase diagram considered metastable?
