QI / Two metals Beryllium (Be) and Silicon (Si) have melting points 1282°C and 1414 °C respectively, are completely soluble as liquids but completely insoluble as solids. They form a eutectic at 1090°C containing 61 wt% Si -39wt% Be? Determine the following:- C 1- Draw the thermal equilibrium phase diagram and identify all phases are present in diagram,then sketches what happens in microstructure when the alloys containing, a- 10wt% Si, b-70wt%Si, solidify completely. 2- Determine the composition and the amount of each phase for the alloy which contain 15 wt% Si-85wt% Be at 1150°C.If the alloy is hypoeutectic or hypereutectic and determine the amount of eutectic at 600 C2
