Question details

Use the attached Ag-Pt phase diagram to answer:Atomic Percent Platinum 20 10 30 40 50 60 70 80 90 100 1800 1769.0° 1600 1400 1200 31.3 84(Pt) (Ag) 1000 1.93 C 800 600 10 20 30 40 50 60 70 80 90 100 Ag Weight Percent Platinum Pt

A molten alloy of 90at% Ag-10at% Pt is slowly cooled from the liquid state at 1200 °C.

(a)What is the composition of the allioy as a weight percentage (wt%)?
(b)What temperature does it start to solidify?

(c)) At what temperature is it fully solidified?

(d)At 700 °C what phases are present and what are their respective compositions as a weight percentage (wt%)?

(e)If the total mass of the alloy is 100 grams, what is the mass of each of the two phases in part (d) at 700°C
