The Formula of Dependence of Mechanical Characteristics of Materials on Crystalline Phase Composition in the Matrix: A Recent Study

Abstract

The dependence of macro-mechanical properties of consolidated body on crystalline phase composition, dimensions, form, distribution in matrix, and form factor plays an important role in materials science and, more broadly, in long-term operation of work-pieces in industry. While working in responsible fields of technology of ceramics and ceramic composites the above referred properties are attributed extremely great role with the view of durability and endurance at the terms of heavy mechanical loads. The crystalline phase plays the most important role in mechanical strength or deformation of any material when describing the resistance of any concrete type work-piece. It is crucial in the correlative explanation of materials mechanics and matrix properties. The role of a macro- and micro-structural component, specifically the crystalline phase, in the transition of stable states of materials into meta-stable states is extremely important in our case because the destruction of ceramic materials and composites will give us an exhaustive response to the role of macro- and micro-mechanical properties of materials.Our research aims to develop a formula for the dependence of macro-mechanical properties of ceramic and ceramic composites on crystalline phase, the most powerful component of their structure, which will allow theorists and practitioners to correctly select and develop technologies and technological processes. On the basis of the study of micro- and macro-mechanical properties of ceramics and ceramic composites and the morphology of crystalline phase and the analysis of the study we determined and created parameters of the formula. When the work-piece is thoroughly destructed, the formula covers macro-mechanical properties: mechanic at bending at three and four-point load, mechanic at contraction; among morphological characteristics: composition of crystalline phase and their spreading in matrix, their sizes, form factor; correlative dependence of the above listed properties. A completely new definition of the factor of crystalline phase spreading in matrix is proposed. The developed formula is of consolidated nature and can be used in ceramic material and ceramic composites technology. The formula will assist practitioners in correctly planning and carrying out all positions of technology of work-piece production, carrying out the most responsible thermal treatment process of technology of work-piece production, and determining the correlation between mechanical and matrix properties of materials.
