 Solid solution strengthening

Resistance to dislocation motion caused by substitutional or interstitial solutes and their interactions with the dislocation strain field and core.

Solid solution strengthening is a mechanism that enhances the strength of a material, particularly metals, through the intentional introduction of alloying elements into its crystalline structure. This process involves dissolving one or more solute elements into a solvent metal to form a solid solution, which results in a significant increase in yield strength and hardness compared to the pure metal.
