Polarized light microscopy: utilization in the investigation of the recrystallization of aluminum alloys

Local deformation and processing maps of as-cast AZ31 alloy

“…Thus, the colours obtained related to the qualitative grain orientation can be correlated to the resulted grey scale. This technique was used in previous work to study microstructural changes in aluminium [17]. The simulations of the compression tests were carried out with DEFORM TM 2D to obtain the local strain and the strain rate in the sample after 0.5 of total logarithmic strain.…”

Effects of initial grain size on hot deformation behavior of commercial pure aluminum

“…This technique is mainly issued for the study of the initial stages of recovery and recrystallization. Since the first germs of new grains are often too small to be detected by light microscopy [37]. Using the above technique, three different initial grain sizes of test specimens were examined as shown in Fig.…”

The Evolution of Microstructure and Mechanical Properties of Al-Mn-Fe-Si Alloys During Isothermal Annealing

“…By adding small amounts of zirconium into aluminum alloys metastable coherent dispersoids Al 3 Zr with cubic L1 2 structure can be formed. They can retard the motion of lattice * corresponding author; e-mail: pokova@karlov.mff.cuni.cz dislocations and grain boundaries and contribute to a better stability of the microstructure at elevated temperatures [12,13]. These particles can be formed during isothermal annealing at 450…”
