Figure 11
The image shows two electron microscope images side by side, each representing the nanoscale surface structures of a material. Image (a) displays a surface with visible roughness and porosity, captured at a high voltage of twenty kilovolts, with a working distance of fifteen point eight millimetres. The view field is set at two hundred eighty micrometres, and it has a magnification of one thousand times. Image (b) showcases similar surface characteristics, taken at the same high voltage but with a shorter working distance of thirteen point five millimetres. It retains the same view field and magnification settings. Both images include a scale bar of fifty micrometres and descriptive text about the microscope used, indicating performance quality in nanospace.The fracture imaging of Charpy (a) and tensile sample (b) after Type 2 heat treatment made in Aluminium 2024-RAM2C. The image was taken with the SEM - Tescan VEGA3 (magnification: 1,000Ă—)
