An alloy system consists of two metals A&B which are soluble in each other in all proportions in the liquid state, but completely insoluble in the solid state. The melting point of metal A is 425°C and B is 375°C. The lowest melting point (Eutectic) is 230°C at 40%B. For a 40 wt% B alloy at 450°C, the phases weight are 0 kg A, 0 kg B and 1 kg Liquid 0 kg Liquid and 1 kg A O 0.5 kg B& 0.5 kg A O 0.35 kg A and 0.65 kg B
