solid solution strengthening

Solid solution strengthening is a method used to make metals more durable by adding small amounts of other elements. When these added atoms replace some of the metal atoms in the crystal structure or fit into spaces between them, they create tiny distortions. These distortions hinder the movement of dislocations—defects that allow metals to bend or deform—thereby increasing the metal’s strength. Essentially, the presence of foreign atoms acts like obstacles within the metal's structure, making it harder for the metal to deform under stress, which results in a stronger, more resilient material.
