  • Method for enhancement of grain boundary cohesion in crystalline materials and compositions of matter therefor
    Publication number: 20040047758
    Abstract: A method for identifying additive components for polycrystalline metals and materials that enhance grain boundary cohesion and compositions of such materials comprises calculation of an empirical value &Dgr;BAwhich is dependent upon a summation of various energy values associated with the matrix and additives and identifying the additives having a negative value. Formulations of alloys having improved physical properties and their processing steps are also disclosed.
