defectsporosity
Defect porosity refers to the presence of voids or pores within a solid material that are considered defects. These pores are typically unintentional and can significantly impact the material's properties, often in a detrimental way. The formation of defect porosity can occur during various manufacturing processes, such as casting, welding, sintering, or additive manufacturing.
In casting, porosity can arise from trapped gas bubbles, solidification shrinkage, or impurities. In welding, it
The presence of pores can reduce a material's mechanical strength, ductility, and fatigue life. They can act
