-
ATrue
-
BFalse
-
CPartly true: properties depend only on cooling rate
-
DCannot be determined without composition
Answer
Correct Answer: False
Explanation
Concept
- Cast irons, including white cast iron, characteristically have high compressive strength and low tensile strength.
- White cast iron has cementite networks that make it hard and brittle, leading to very poor tensile ductility and strength but good compressive capacity.
ThereforeThe statement reverses the usual trend and is incorrect.
Final AnswerFalse
