solidification of Al-alloy (Equiaxed crystal)
Posted: Sun Jan 23, 2022 4:03 pm
Dear Bernd,
I am using MICRESS for research on the solidification process of aluminum alloys. Also encountered some problems. First of all, I think that the solidification process should be accompanied by the release of latent heat. I set up several heat extractions, whether it is at 7J/(s·cm3) (fig.a) or 50J/(s·cm3) (fig.b), the results of simulation are all cellular equiaxed crystals, which are inconsistent with the experimental results. In the experiment, I used a cast iron mold capable of casting about 1 kg of castings. The results of changing different processes are the coexistence of equiaxed crystals and dendrites. I believe that a wide solidification temperature range of metals should be cast as I experimented, but I don't know what went wrong with the simulated process.
Attached is a metallographic photo of me.
Looking forward to your reply and wishing you a Happy Chinese lunar New Year in advance.
