the study of nucleation mechanism of new grains during severe plastic deformation of magnesium alloys is of great importance to control the characteristics of final microstructures.  to investigate the role of discontinuous recrystallization, a wrought az31 magnesium alloy was deformed by accumulative back extrusion process at 330 °c.  the obtained microstructures were studied using optical and...

Laser Scanning Microscopy Techniques such as Confocal Microscopy, Two Photon Excitation Microscopy, Second Harmonic Generation Microscopy or Fluorescence Lifetime Imaging have been successfully employed to date for imaging skin cancer. However, the resolution that such techniques can provide is limited by diffraction, which prevents accurately imaging (and differentiating) optical details sized...
