Prospects of In-Situ α-Al2O3 as an Inoculant in Aluminum: A Feasibility Study
Source abstract
Abstract
In-situ a-Al 2 O 3 was successfully synthesized and dispersed in Al alloy using B 2 O 3 and ultrasonication-aided liquid mixing technique. Microstructure analysis identified a-Al 2 O 3 as the most common phase in the composite master alloy, whereas AlB 12 was frequently observed and AlB 2 was rarely found in the alloy. Grain refinement analysis of selected Al alloys registered a transition of columnar to equiaxial grains of a-Al with the inoculation of the master alloy and ultrasonication treatment. Similarly, an improvement in the mechanical properties of A357 alloy was observed with the combination of inoculation and ultrasonication treatment.
