AMG Aluminum – The global leader in aluminum alloys

The controlled addition of AMG Aluminum's titanium boron aluminium TiBAl™ grain refiners to molten aluminium releases nucleant particles that promote equiaxed, fine grain structure throughout the cast alloy, thus avoiding formation of columnar crystals. Casting speed can also be increased, and improved characteristics achieved.

Grain refining of aluminium and its alloys using ...

Jul 18, 2013· Grain structure is an important and readily observable feature in cast aluminium alloys. Three different types of grain morphology are possible, namely, columnar, twinned columnar, and equiaxed. Inoculants in the form of master alloys are used to promote the formation of a fully equiaxed grain structure and this is termed grain refinement.
