Solid Solution Dislocation Density
The solid solution dislocation density indicates how many lattice defects occur per unit volume in a crystallite. It strongly influences work hardening.
Physical-chemical mechanism of action
The solid solution dislocation density is a measure of the number of lattice defects per unit volume within a crystallite. These defects can arise from mechanical loads, chemical reactions, or thermal deformation.
Metallurgical relevance & risks during welding
A high solid solution dislocation density can lead to increased cold working. This can change the material's structure, leading to increased hardness and higher demands on the welding process. Excessive work hardening can lead to cracking or fracture.
Workshop practice & instructions
To ensure an optimal solid solution dislocation density, it is important to carefully adhere to welding parameters such as temperature and time. For heavily hardened materials, additional processing steps such as austenitizing or tempering should be applied to regulate the structural states.
