Briefly why? b) Draw a schematic stress-strain diagram for tensile bars cut from side I and from side II. 0) Suppose samples from side I and side II are heated to 0.8Tm. Briefly describe how the microstructure of each sample would change under annealing. (1) Suppose the rolling process were done not on a metallic alloy but instead on a ceramic material like silicon nitride (Si3N4). Briefly sketch the microstructures you might expect for side I and side II. 6) Suppose the rolling process were done not on a metallic alloy but instead on a themeplastic polymer like poiy(ethylene).
