← HistoryWhich outcome arises due to liquation during early bronze casting?
A)Compositional segregation within the alloy✓
B)Increased tensile strength near surface
C)Uniform grain structure throughout casting
D)Decreased hardness at core regions
💡 Explanation
Improper cooling causes compositional *segregation*, called liquation; the lower-melting phases solidify at grain boundaries, because the last material solidifies there. Segregation reduces strength at those boundaries; therefore overall it will likely decrease its strength rather than make it stronger at surface.
