Lattice Distortion Energy

Physicochemical mechanism of action

Lattice distortion energy arises from distortions in the crystal lattice or from the introduction of foreign atoms. These distortions increase the chemical potential and impair the order of the lattice.

Metallurgical relevance & welding risks

The increased energy can lead to slower diffusion, which affects the hardness and strength of the material. Improper handling during welding can lead to phase transformations or the formation of cracks.

Workshop practice & instructions

To minimize lattice distortion energy, ensure a clean molten pool and controlled cooling. For high-hardness steels, regulate the carbon content to achieve a stable phase structure.
