Aluminium is our passion. And our knowledge! Benefit from our knowledge.
Many information can be found in aluminium-manual, which is being completely revised and will soon be available. In the meantime, please use our glossary for useful word explanations.
- Grain boundary
Grain boundaries are 2D defects in the crystal structure; the interface between two grains, or crystallites, in a polycrystalline material.
- Grain growth
Increase in size of grains (crystallites) in a material at high temperature making the material more brittle and less resilient; arises through overheating or too long hold times during the heat treatment.
- Grain refinement
Generation of a finer grain in the structure by appropriate heat treatment of melt, leads to increase the strength and toughness of the workpiece.
- Gravity die casting
Substance which slows, inhibits or prevents the reactions of chemical, biological or physiological nature.
