1 picture- problem 2 other pictures- phase diagrams for problem 1. Draw a phase diagram for a binary eutectic alloy with solid solubility, naming and describing the significance of the main features. The binary alloy system of metals A and B contains two intermediate (intermetallic) phases A B and AB2 of narrow composition range, each of which forms by a peritectic reaction A cutectic point also exists, at 85at% B. The melting point of A is higher than that of...
