1) Fill in the blanks (or) State True or False for the following questions (12 points): a. (True/False) During steady-state creep, the material experiences elastic deformation. b. (True/False) Tempering decreases the brittleness of steel. c. (True/False) Hooke's law is only applicable in the elastic region of the stress-strain curve. d. Smaller the crystal size, e. Higher the planar density, f. is a common type of failure mechanism in yellow pine wood samples which is indicative of separation of layers. (stronger/weaker) the material. (higher/lower) the corrosion. 2) A: In the microscopy experiment, we studied about the crystal structure and corrosion resistance of Al 2024 alloy subjected to different rates of cooling. Based on what you learnt, propose a strategy to form the strongest yet corrosion resistant Al 2024. Explain the mechanism by which these properties are achieved. (6 points). B: In the 100X images of the A12024 samples, the deep purple regions are crystals (2 points) 3) A: List the three different mechanisms of heat transfer that take place during the Jominy test demo experiment (3 points) B: What form of steel is formed when the Jominy bar is heated to a 1000 °C and then quenched to room temperature. Comment on the mechanical properties and corrosion resistance of this form of steel? (4 points)
