Tiheydyksen
Tiheydyksen is a Finnish term commonly translated as densification, referring to processes that increase material density during processing by reducing porosity and increasing mass density. In materials science, tiheydyksen describes the evolution of porosity and solid fraction under pressure, temperature, or diffusion.
The term derives from the Finnish word tiheys, meaning density, with the -dyksen suffix indicating a genitive
Mechanisms of densification include particle rearrangement, plastic deformation, and solid-state or viscous diffusion that closes pores
Common processing routes that drive tiheydyksen are powder compaction, cold or hot pressing, sintering, hot isostatic
Density measurements are essential to quantify tiheydyksen. Techniques include the Archimedes principle, density meters, pycnometry, and
Applications of densification processes span ceramics, metals, composites, and polymers, where higher density typically improves mechanical
