Kolokoltsev V.M., Goltsov A.S., Shevchenko A.V. Complex effect on the melt of alloyed white irons in purpose to improve the it properties
Complex-alloyed white irons (CAWI) are perspective material for the production of cast details for equipment, working in difficult conditions of wear at elevated temperatures. Highly effective impact on the formation of structure and properties of castings from CAWI is possible by combining of processes of modification, refining and hightemperature treatment of melts (HTTM). Modes of HTTM and the optimal amount of refining-modified materials for CAWI were selected with the help of performed practical researches. The research of examined methods of increasing the operational stability of castings gave chance to work out the new refining-modifying complex.
Key words:Iron, microallowing, refining, thermo-time treatment.

The article describes an idea developing by the author which enables to consolidate computer-aided analysis of cast component and casting technology. Simulation according to the conception takes into account the inhomogeneous structure of cast alloy and regular distribution of shrinkage porosity. Such structural parameters determine non-uniform mechanical properties in casting. As an example of application the simulation of cast component produced by centrifugal casting technology was viewed. The casting was made of super-invar alloy Fe-32%Ni-4%Co.
Key words:Computer simulation, structural strength, cast alloys, super-invar.
