The magnetic secret inside steel finally explained

SMRTR summary

Researchers at The Grainger College of Engineering have solved a decades-old mystery by identifying why magnetic fields slow carbon atom movement in steel, using computer simulations to show that aligned magnetic spins create higher energy barriers for carbon diffusion. This breakthrough could enable more energy-efficient steel production and lower CO2 emissions.
