Description
Qin Qin and co-authors simulated how iron freezes under distinct cooling setups in 2024. Freezing shapes the crystal mix and stress inside metal parts. The team used molecular dynamics to compare even cooling against cooling with a temperature slope across the sample.
With even cooling, crystals popped up all at once and the cubic phase surged near 1431 K. With sloped cooling, crystals formed steadily and the freeze front crept toward the warm side, under higher stress. Faster cooling or a steeper slope sped the change and cut leftover stress in the bulk. Boundary zones, though, kept higher stress and uneven structure under those same settings.
