In order to figure out whether Gallium works in the superalloy K444, its composition had been modified by adding about 0.003 wt.% and 0.01 wt.% Ga, respectively. Mechanical properties of the modified superalloy K444 were investigated by using scanning electron microscopy (SEM) after standard heat treatment. Gallium had no significant effect on the tensile strength at room temperature and 900 °C. Gallium had a little effect on the tensile plasticity at room temperature and 900 °C. The plasticity is better in the modified K444 alloy containing 0.003wt. % Ga, however, the plasticity became worse in the alloy containing 0.01wt. % Ga. As for plasticity, the optimum Gallium content should be 0.003 wt. % for the superalloy K444.
