Explanation / Answer
At 1200 degree Celcius Nb 40wt% W ; Mass of alloy = 1200 lbs ==> Mass of Tungsten = (40*1200)/100 = 480 lbs From graph you can see that at 2800 degree celcius liquidus line (line separating liquid from mixture of liquid + solid) have composition of approx. Nb 50wt% W and at this point first solid forms. Mass of alloy = 1200 lbs Mass of Tungsten at that point = (50*1200)/100 =600 lbs Initial mass = 480 lbs Final mass = 600 lbs Amount of Tungsten to be added = 600 - 480 =120 lbs PART B) Entire bath becomes solid below solidus line (line separating solid from mixture of liquid + solid) From graph you can see that at 2800 degree celcius solidus line (line separating solid from mixture of liquid + solid) have composition of approx. Nb 70wt% W and at this point entire bath becomes solid . Mass of alloy = 1200 lbs Mass of Tungsten at that point = (70*1200)/100 =840 lbs Initial mass = 480 lbs Final mass = 840 lbs Amount of Tungsten to be added = 840 - 480 = 360 lbs
