Choose an option
-
AYield point increases
-
BDuctility decreases
-
CUltimate tensile strength increases
-
DAll of these
Answer
Correct Answer: All of these
Explanation
Given
- Normalising heat treatment of steel.
ConceptNormalising refines grain size and produces a more uniform pearlitic/ferritic structure than annealing. This typically raises strength (UTS), raises yield point, and reduces ductility compared with the annealed state.
