9- For two metals "A" & "B" the eutectic point is (72; 780) Four points were detected in the phase diagram as follows: Point Note (5; 1080) a nuclei of a solid solution had been detected (5,950) a nuclei of liquid still remains in the alloy (100; 1000) start of solidification (95;600) lies on a solvus line Knowing that at room temperature the two metals are pure and all the given compositions are percentage of metal "B" determine the following: a-The melting points of the two metals b-The maximum solubility of each metal in the other
