Grain growth was studied in high purity Al-Ga alloys with Ga contents of 0.001, 0.005 and 1 wt.%. The transition from normal to abnormal grain growth was investigated in dependence on Ga content and temperature. The orientations of individual grains were determined with aid of the selected area channelling method in the contact area between the abnormally growing large grains and normal matrix. The grain boundary wetting phase transitions were also studied in Al-Sn and Al-Sn-Ga alloys.
