By heating the material to a specific temperature, elements within the solid solution dissolve into the crystal lattice. Cooling at a controlled rate then enhances the material's mechanical properties and microstructure.

1. Improving Mechanical Properties

Effectively enhances mechanical properties such as tensile strength, yield strength, and toughness. This occurs because heating during solution treatment dissolves elements within the crystal lattice, altering the crystal structure and dislocation density. This reduces defects and enhances the material's mechanical properties.

2. Improving Microstructure

Enhances microstructural characteristics such as grain size, grain refinement, and lattice stress. This is achieved by promoting recrystallization and eliminating lattice stress and orientation deviations during solution treatment.
