Solution
The correct option is A Steel is more rigid resulting in a decrease in both malleability and ductility Ans : (D) Steel is more rigid resulting in both malleability and ductility.
- Steel is interstitial alloy composition (iron and carbon)
In this carbon atoms fit between the metal atoms and provide extra bonding to neighboring atoms, which makes alloy harder, stronger and less ductile and malleable.
