摘要：

The surface tension of pure aluminum obtained by the maximum bubble pressure method under nitrogen atmospheres is investigated. The results indicate that nitrogen decreases the surface tension of pure Al well below the value obtained under inert atmospheres (Ar). The effect is associated to the reaction between Al and nitrogen to form AlN that occurs at temperature above 850 degrees celsius.
