The purpose of the work is to identify the possibility of expanding the nomenclature of cast parts, which must withstand heavy loads with additional working conditions on impact. Influence of chemical composition of modified cast iron, austenization temperature, temperature and time of isothermal holding on mechanical properties of bainitic high-strength cast iron. Study of features of conditions of appearance of TRIP-effect in the surface metal layer. Detection of boundary conditions for work of parts made of high-strength bainitic cast iron working in soil with the presence of stones. Manufacturing of the necessary technological equipment for casting of parts working under different loading conditions. Conducting comparative tests of batch steel parts and parts made of high-strength bainitic cast iron of the optimum chemical composition and heat treatment modes. Making recommendations when using bainitic high-strength cast iron for parts. working at high loads, including shock. Methods of research - metallographic analysis, methods of mechanical testing, X-ray structural analysis, scanning electron microscopy, field tests in soil cultivation. The study was conducted using modern standard equipment and apparatus. Product Description popup.authors Voloshchenko Serhiy M Podrezov Yuriy M popup.nrat_date 2020-10-01 Close
