Figure BI below shows the equilibrium phase diagram of hypothetical A - B alloy system. Answer the following questions. Now assume a melt of Alloy B has a weight of 100 g at a temperature of 652 °C. Maintain the temperature, suggest how to make this melt become a completely solid phase Based on Figure B1, briefly illustrate how to design and achieve a precipitation hardening for A-B alloy.

In Figure 1 (phase diagram), an alloy composition of 95 wt% Mg and 5 wt% Al is cooled from 700 C to 475 C. An analysis of the resulting ε solid-phase composition reveals that it has a higher Mg content than is anticipated by the phase diagram.a) Explain why this might be the case and how your reasoning results in the higher-than-expected Mg content.b) Provide a sketch showing the likely distribution of Mg content within the volume of ε solid-phase.

Referring to Figure 1, please answer the following [NOTE: SHOW YOUR WORK on Figure 1]:a. provide the specific name for the phase boundary lines denoted by A and B. b. identify the phases present at equilibrium in the phase fields denoted by C, D, and E. c. identify the specific name for the point denoted by F. d. What is the maximum solid solubility of Mg in Al? At what temperature does it occur? e. An Al-Mg alloy (10 wt% Mg, 90 wt% Al) is heated slowly (to insure equilibrium) from a temperature of 200 C:    i. At what temperature does the first liquid phase form?    ii. What is the composition of the liquid phase at the temperature in part i.?  iii. At what temperature does complete melting (no solid phase remaining) occur?  iv. What is the composition of the last solid remaining prior to complete melting? f. Using the equilibrium phase diagram of Figure 1, identify the phases present, their compositions, and their relative mass fractions at equilibrium for a 70 wt% Mg – 30 wt% Al…
