Metals A and B form compounds AB3 and A2B3. Solids A,B,AB3, and A2B3 are essentially immiscible in each other, but are completely miscible as liquids. A and B melt at 600C and 1100C, respectively. Compound A2B3 melts congruently at 900C and gives a simple eutectic with A at 450C. Compound AB3 decomposes at 800C to give the other compound and a melt. There is a eutectic at 650C. Draw the simplest phase diagram consistent with this information. Label all phase regions
