← ScienceWhich consequence results when metastable austenite undergoes decomposition in steel?
A)Increase in material hardness value✓
B)Reduction in the ductile properties
C)Decrease volume expansion coefficient
D)Stabilization in electrical conductivity
💡 Explanation
Martensitic transformation increases hardness because the diffusionless transition produces a distorted crystal structure hindering dislocations. Therefore, the material hardens, rather than becoming softer or changing other properties directly related phase changes like electricity because the prime product is hardness increase.
