← ScienceWhich outcome occurs when rapid quenching of a molten alloy prevents thorough lattice alignment?
A)Increased material hardness and brittleness✓
B)Enhanced crystalline grain boundary diffusion
C)Higher electrical conductivity and ductility
D)Decreased resistance to thermal creep
💡 Explanation
Rapid quenching introduces crystal defects because the limited time prevents complete atomic ordering via the mechanism of crystal growth. Therefore, hardness increases because these defects impede dislocation motion rather than promoting ductility.
