Explanation
The supersaturated solid solution is heated at room temperature (natural aging) and above room temperature below the solid solubility line (artificial aging)? The phenomenon that the hardness is significantly increased than the supersaturated isosolution in the quenching state. The reason for hardening is that the supersaturated solid solution undergoes precipitation, segregation, order and other reactions during aging, resulting in precipitation, which increases the resistance of dislocation movement.
