9. Short Answers - be as brief a possible (15 points) a) (5 p) Use the Orowan equation to explain how a yield point may take place during a constant strain- rate experiment on a well aligned, well annealed single crystal. b) (5 p) If the dislocation velocity v is controlled by a thermally activated process, discuss what information that can be obtained by changing the strain-rate during a plastic deformation experiment? c) (5 p) Is the following dislocation reaction favorable in a cubic crystal? [112]+[21] → [301] Explain the basis for your reasoning.
