12mm $2 (a) A single crystalline dog bone shape NiCoCr alloy exposed to 700 N uniaxial force along the [001] direction. The width of cross section is 3 mm with 1 mm thickness. Please find out if this material will be yield on the (111) [110] (15 points). (b) If this tension specimen is failed when the force is 1200 N and the total elongation is 20 mm, Could you please calculate the true stress and strain values? The gage length of the material is 8 mm. (10 points) CRSS: 50 MPa c) Suppose that a carbon steel is tested first at room temperature. Then, the equivalent tensile specimen is tested at low temperature that is lower than ductile-brittle transition temperature. Please draw a schematic tensile curve for both cases to indicate differences of yield strength, ultimate tensile strength and toughness of both cases. (10 points) d) Please explain how to calculate elastic modules (E) of a steel on a tensile curve (5 points).
