Abstract Scope |
In the present paper, we describe in-situ heating experiments on rolled AZ31, AZ91 and pure Mg alloys using high-energy synchrotron X-ray diffraction in both Spring-8 (Japan) and DESY (Germany). We found that X-ray diffraction provides rich information on heat-mediated transformation processes, which lead to the formation of different intermetallic phases. The azimuthal distributions of diffraction intensity for each peak can be extracted from the two-dimensional diffractograms within one frame. In-situ synchrotron experiment provides us with thousands of frames during heating, from which important information on the recovery, recrystallization, grain growth and grain rotation processes to be investigated in detail from the multi-dimensional azimuthal-time plot. In addition, texture evolution upon heating can be detected using this data analysis. The obtained results demonstrate that the in-situ synchrotron diffraction combined with multi-dimensional data analysis is a powerful tool to investigate the microstructure evolution in metals and alloys. |
