Evaluation of Surface Energy of W and AlNi by the Results of Their Milling

摘要

A method is proposed which is an alternative to existing methods of determining of the surface tension of solids and is based on a generalization of the Rittinger law and the Gibbs thermodynamic equations, as well as on a diffraction analysis of the granulometric characteristics of finely dispersed powders of templates (Fe, Co) and originals (W, AINi). The surface tension coefficients of tungsten and AINi are evaluated. The confidence intervals of varying their values are found.
