Question

Consider the following hypothetical binary cutectic phase diagram on which two alloys of compositions X1-30 B wt% and X1.50 B

What is the fraction of primary β in the X2 alloy that forms under equilibrium cooling at eutectic temperature?

What fractions of primary α and eutectic micro-constituent composition are formed in the X1 alloy below the eutectic isotherm?

What amounts of α and β form from liquid just below the eutectic temperature in the X2 alloy?

What are the amounts of total α and the eutectic α in the X1 alloy at a temperature just below the eutectic temperature?
