MODERN TRENDS IN CONSTRUCTION MATERIALS TECHNOLOGIES

Abstract

The monograph is devoted to the actual scientific and practical problems of materials science, foundry production and engineering and architectural solutions, which are of great importance for the industrial development and post-war reconstruction of Ukraine. The book comprehensively combines research in the field of creation of new metal materials with increased operational properties and development of inclusive and sustainable engineering approaches in construction and environmental design.

The first chapter substantiates the rational compositions of chromium-manganese alloys and investigates the regularities of formation of their structure, phase composition and properties in the cast state. The possibilities of reducing the energy intensity of casting processes and increasing the wear resistance of products compared to traditional alloys-analogues are shown. The prospects of using the developed materials to increase the operational stability of piercing mandrels of pipe rolling mills are determined, provided that the heat treatment regimens are optimized and metastable self-strengthening structures are formed.

The second chapter is devoted to the integration of the principles of inclusive engineering and artisanal technologies in the design of public catering establishments in the conditions of post-war reconstruction of Ukraine. The choice of environmentally friendly building materials and architectural solutions that ensure accessibility, safety, energy efficiency and compliance with sanitary and hygienic requirements (HACCP) is justified. The proposed approach contributes to the sustainable development of communities, reducing the environmental load and preserving local cultural identity.

The third chapter considers promising high-entropy alloys based on the FeNiCrCuAl and FeNiCrCuMn systems as heat-resistant casting materials of a new generation. Based on thermodynamic calculations, structural-phase analysis and research of thermophysical, mechanical and casting properties, their high structural stability and feasibility of use in conditions of elevated temperatures are confirmed.

The fourth chapter highlights the scientific and technological prerequisites for obtaining steel hollow castings with composite and reinforced non-metallic fillers by the casting method using gasified models. A mathematical description of gas-hydrodynamic processes has been developed, computer modeling and experimental verification of technological solutions that are important for the manufacture of special and protective casting products have been carried out.

The book is addressed to scientists, practicing engineers, foundry specialists, architects and designers, as well as scientific and pedagogical workers and higher education students in the specialties of materials science, metallurgy and civil engineering.
