The Pb% to gain alpha grain with Mg2Pb on the boundary of alpha at the room temperature. ANSWER: From the diagram, the required Pb% is 40% since it corresponds to the boundary eutectic. 2. Is it possible to gain beta grain with Mg2Pb on the boundary at the room temperature of an alloy? Explain ANSWER: It is not possible to get grain on Mg2Pb since the eutectic composition will be varied, which in turn will lose the composition strength. 3.
