Question 2

If the partition coefficient k is less than unity (k<1) in a binary alloy, what is the primary consequence during solidification?

Question 3

In casting, what is the characteristic difference between equiaxed and columnar grain structures?

Question 4

Which factors most directly control the transition between planar, cellular, and dendritic solidification morphologies?

Question 5

For a binary alloy with a solidus composition of 2 wt% and a liquidus composition of 10 wt%, if at a given temperature the liquid composition is 6 wt%, what is the fraction solid f_s according to the lever rule?
