Binary phase diagram of an aluminum – silicon mixture
Data: Tmelt(Al) = 660 °C
Tmelt(Si) = 1412 °C
Silicon forms an alloy in the liquid state (total miscibility) with aluminum. The two metals are not
miscible in the solid state. The temperature of solidification of the Si-Al alloy is minimal at 580 °C
for a mass fraction of silicon wSj equal to 0.125.
Give a representation of the liquid-solid diagram T=f(wSi) that takes into account these data.
One will assimilate liquidus curves to straight lines.
