Aluminium scandium alloy
= Aluminium scandium alloy
An <aluminium scandium alloy> contains scandium added to aluminium, often in a relatively small proportion. Scandium-containing precipitates and changes in grain structure can influence strength and stability.
The strengthening effect depends on microstructure and processing, not simply on adding the masses of two pure metals. It provides an example of how a minor alloying element can strongly alter dislocation motion and grain evolution.
