Inclusion Morphology
Inclusion morphology describes the shape, size, and distribution of non-metallics in metal materials. This property strongly influences crack formation.
Physico-chemical mechanism of action
Non-metallic inclusions such as contaminants or additives have a specific geometric shape and size. Their spatial distribution in a metallic material influences how these inclusions react under mechanical loading.
Metallurgical relevance & risks in welding
Inclusions can cause cracks and fracture points. If they are too dense or too large, they can severely impair the strength of the material. During welding, the structure can be rearranged, which changes the inclusion morphology and may create new crack sources.
Workshop practice & operating instructions
When welding, it is important to carry out careful surface treatment to remove non-metallic inclusions. Welding parameters such as temperature and time must be precisely adhered to in order to control the structure so that the inclusion morphology is minimized. For special materials, special treatment may be required to prevent crack formation.
