Platinum and gold are completely soluble in both the liquid & solid states. The following table gives the solidification temperatures for the different alloy composition. Alloy Wt. % of Au Solidification beginning temperature. Solidification ending temperature 0 1750 1750 20 1690 1530 40 1580 1360 60 1470 1250 80 1310 1170 100 1150 1150 Draw the phase diagram to the scale & label different regions. For an alloy containing 70% Gold, determine the following. 0 a. Chemical composition and relative amount of the phases present at 1325 C. b. Temperature where there is equal proportions of solid & liquid phases present. Platinum and gold are completely soluble in both the liquid & solid states.
