it is about plastic deformation and elastic deformation can you explain annealed case and non-annealed case relation to workhardening and elongation with stress- strain curve and the reason although area decrease, force increase , can you explain this with slide, twinning, dislocations, heat change ?

A metal has a toughness of 748 MPa. Elastic deformation terminates at a strain of 0.010, and the material fractures at a total strain of 0.55. The modulus of resilience is 2.50MPa. Plastic deformation can be described by the equation sigma = K(epsilon)^n, where n is 0.18, and assume for this metal the equation is validto the point of fracture. A stress-strain diagram is not required but may help you in determining the answer. The student is expected to know...

Why do metals initially exhibit only elastic deformation under low loads? What causes metal plastic deformation to begin at higher stress levels? What occurs in metals on the atomic level that causes plastic deformation at high stress? What occurs in molten metals when they cool and solidify, both initially and then later?
