3. Results and Discussion Here are the test results(figs. 2 to 4). The number of EBSD images captured was 12 for the notched spec imen, 15 for the shear specimen, and 17 for the uniaxial specimen. The progression of the ′ transformation rates obtained from this test ranged from 1.7-90% for the notched specimen, 2.3-11% for the shear specimen, and 0.65-53% for the uniaxial specimen. The fact that the phase remains significantly stable in the shear specimen will be discussed further in the Discussion section. Next, an explanation of the test result figures is provided. These results are presented as a video where the frames overlay to show the progression of loading. The images include SEM images at 50x and 500x magnification, along with phase maps and Euler maps captured by EBSD at 500x magnification.
