Which outcome occurs from exceeding the Leidenfrost effect temperature during quenching?

A)Slower than predicted cooling occurs
B)Martensite formation becomes thermodynamically favourable
C)Nucleate boiling collapses on the surface
D)Maximum heat flux is rapidly achieved

💡 Explanation

Exceeding the Leidenfrost point enters film boiling, therefore decreasing heat transfer because a vapor layer acts as an insulator; consequently, the cooling rate plateaus, rather than alternatives that exhibit optimal heat transfer and do not experience this insulating layer.
