Explain and discuss briefly: (1) Whether a larger fracture toughness is associated with an additively manufactured Fe- 0.6wt%C product that is fast cooled after the additive manufacturing OR an additively manufactured Fe-0.6wt%C product that is slowly cooled after the additive manufacturing. (2) Is there any residual stress in the first product? What is the reason? How to reduce this residual stress in the product?
