Question:
The fine austenite grain size in steel increases
The fine austenite grain size in steel increases
Show Hint
Fine-grained materials generally exhibit improved toughness and resistance to impact, making them ideal for applications requiring high strength.
Updated On: May 5, 2025
- Corrosion resistance
- Hardenability
- Creep strength
- Impact toughness
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
A finer austenite grain size in steel improves its impact toughness, which is the material's ability to absorb energy before fracturing.
