2. CHEMICAL STRUCTURE
2.1. Molecular Structure
Aluminum Titanium Boron master alloy consists of TiAl₃ and TiB₂ intermetallic phases dispersed within an aluminum matrix. These phases, homogeneously distributed in the aluminum matrix, function as grain refiners in aluminum alloys. During solidification, they form nucleation sites, refining the grain structure and improving mechanical properties.

-
Wash hands thoroughly after handling.
-
Use vacuum or inert atmosphere (Ar, N₂) for melting operations.
-
-
Waste Management:
-
Dispose of in accordance with local regulations.
-
Do not discharge into water sources.
