Abstract
The paper presents results of the investigations pertaining to creation of scientifically substantiated criteria for selection of alloying components and base compositions for manufacturing of mechanically alloyed dispersion-strengthened metallic materials. An analysis of dispersion strengthening mechanisms and regularities in mechanically activated phase and structural transformations serve as a reliable basis for solution of the assigned mission. Foer efficient strengthening at low and high temperatures as well materials must have fragmented and polygonized structure with maximum developed surface of grain and sub-grain boundaries which are stabilized by nano-sized inclusions of strengthening phases. Experimental investigations have shown that an optimum complex of mechanical properties is obtained in the case when nano-sized strengthening phase is equal to 3–5 % (volume). The phases applied for dispersion strengthening must have high value of shear modulus that determines their hardness and strength. Critical compressive stress should not cause deformation and destruction of disperse particles. Furthermore, they must have high stability in contact with a matrix. The substances applied as alloying components for realization of the developed technology on obtaining dispersion-strengthening materials must firstly meet the following requirements: they must be cheap, accessible and ecologically safety; they must interact with the basis or inter se at temperatures which are lower of material melting temperature; one of the phases which is formed in the process of the technology realization must have rather high thermodynamic stability and high value of the shear modulus; other formed phases must improve or, at the least, not reduce physical and mechanical properties of the materials.
