Spring'17 release of ME-databases

Rod shaped metastable precipitates (see long lines in Fig.) in an AA6xxx were characterized by means of their distribution, size, orientation and shape factor. Thickness measurements of the observed volume allow the estimation of local particle number densities and further their volume fractions. On the right edge of Fig., a grain boundary pinned by dispersoids is visible. The size and the chemical composition (EDX) of these dispersoids as well as the size of the precipitation free zone (PFZ) can be measured. The blurred dark lines and regions are bending contours and thickness fringes of the Al-matrix and are the consequence of the diffraction contrast. All this knowledge gives a qualitative and quantitative insight into the material and allows a better setup of simulations and the optimization of ageing processes.
