← ScienceWhich outcome occurs when austenite transforms in steel alloys?
A)Increased hardness from martensite formation✓
B)Enhanced ductility from retained austenite
C)Reduced corrosion due to ferrite layers
D)Higher electrical conductivity by electron flow
💡 Explanation
Increased hardness occurs through martensite formation because the rapid cooling inhibits carbon diffusion, thus trapping the iron atoms in a distorted crystal structure. Therefore hardness increases rather than ductility, because the deformation mechanism undergoes significant changes.
