This video shows the grain growth during heating: The heating time is 5100 s and the grains start to grow at 3500s, 900°C. The video on the left shows the thermal cycle which is applied at the selected sensor and the video on the right the associated microstructural evolution at the same point from the mesoscale calculation.
The initial average grain size diameter is around 20 µm. At the end of the thermal cycle, the grains have grown due to capillarity with an average grain size diameter of 50 µm.
