Formation Kinetics of TiB \(_2\) in Aluminum Melt Studied Using Laser-Induced Breakdown Spectroscopy

We report Ti concentration measurements in dilute Al-Ti-B alloysAlloys, acquired from direct chemical analysis of the molten metal by laser-induced breakdown spectroscopy (LIBS)Laser-Induced Breakdown Spectroscopy (LIBS). By LIBSLaser-Induced Breakdown Spectroscopy (LIBS) it is possible to analyze the influence of B addition on the concentration of dissolved Ti in the melt. After the addition of B, the dissolved Ti concentration is slowly reduced, with the kinetics strongly influenced by the Ti/B ratio and the melt temperature. The experimental observations are consistent with the formationFormation of TiB \(_{2}\) around Al-borides. The experiments confirm that LIBSLaser-Induced Breakdown Spectroscopy (LIBS) measurements of the liquid metal enable the real-time study of the kinetics of boron treatment.
