Strength and Young's Modulus of Steel with Carbon Content
Strength of Steel and Carbon Content:
- Strength of steel increases with carbon content.
- This is due to the fact that the addition of carbon increases the number of dislocations in the crystal structure, which in turn increases the strength of the steel.
Young's Modulus of Steel and Carbon Content:
- Young's Modulus of steel increases with carbon content.
- This is because the addition of carbon increases the stiffness of the steel, which in turn increases its Young's Modulus.
Young's Modulus of Steel and Variation of Carbon Content:
- Young's Modulus of steel remains unchanged with variation of carbon content.
- This is because the stiffness of the steel is mainly dependent on the crystal structure, and not on the carbon content.
Conclusion:
- Thus, statement 1 and 2 are correct, while statement 3 is incorrect.
- The strength of steel and Young's Modulus are both affected by the carbon content, but in different ways.
