Eutectic mixture is a particular mixture of certain ratio of two components.If pressure changes the eutectic temperature changes.eutectic temperature is lowest melting point among the components present in mixture.The mixture depends upon certain weight ratio of two components.Only certain components makes eutectic with certain components..
Therefore Eutectic temperature depends upon pressure.

Problem 3 A binary system of atoms A and B has a simple eutectic phase diagram (as shown below). The ternary solid solutions are a and R Let an A-rich sample of the composition indicated by the vertical line be solidified from the medt. It is found that its microstructure depends strongly on how rapidly it is cooled. Slow cooling leads to a polygranular structure of grains with small β grains dispersed throughout. Fast cooling leads to a dendritic structure...
Sketch the aluminum-silicon phase diagram from the following data to estimate the proportion of pure silicon in the eutectic alloy just below the eutectic temperature and sketch the possible microstructure.
• It is a eutectic system. • The melting point of pure aluminum is 6600C • The melting point of silicon is 1410 0C • The eutectic temperature is 5800C • Aluminum is insoluble in silicon • The eutectic composition is 85% Al + 15% Si • The Al-rich phase (α) is a solid solution of Si in Al and the maximum solubility of Si in α is 3% at the eutectic temperature • At 500°C the solubility of Si in α has fallen to 0% and...
