The article presents the results of the tests on the wear resistance of chromium cast irons of different compositions obtained in sand forms. It has been shown that increase of the wear resistance and mechanical properties of the cast iron is possible to obtain using the casting in metal molds. A further increase in wear resistance of parts produced in metal molds is possible by changing the technological parameters of casting and alloying by titanium.

The problem of hardening of fusion in a crystallizer from a core side at vertical continuous molding is solved. It is established that hardening of casting from a core side proceeds in 7–10 time more slowly, than from a crystallizer. Influence of a core on the thermal mode of casting during her hardening in a crystallizer during the first 15–20 with slightly, the core didn’t manage to get warm. Settlement thickness of a crust by 20th second of formation has made no more than 1,5 mm. When using thin-walled shell cores thickness of the crust formed on a core has made ξ = 2,0–2,5 mm or less than 10% of casting thickness. Use of continuous cores raises a share of the metal hardening on a core to 15–18%. In this case the coefficient of accumulation of heat a core is accepted equal ξ = 0,75–0,85.

The reactive mechanical alloying is an effective technology for production of nanocrystalline modifying modifiers and ligatures. During smelting chromium bronzes use of mechanically alloyed modifying ligatures allow to exclude from the technology the environmentally hazardous high-temperature process of production of cast ligatures and to reduces reduce the optimum temperature of the melt alloying process copper at 50–100 °C by reducing its duration 2, 5–3,5 times This excluded process requires expensive furnace equipment. Mechanically alloyed modifying ligatures allow the formation of dispersion-strengthened heat-resistant materials with sub -,/ microcrystalline structure type bases, which are strength, hardness, conductivity and temperature of the onset of recrystallization about 15–20% superior to the base, which increases the resistance of the welding electrodes by 1.8–2.2 times. 

Theoretically justified and experimentally confirmed the high efficiency of the technology, based on the reactive mechanical alloying to produce nanocrystalline modifying modifiers and ligatures. Application designed mechanically alloyed modifying ligatures allows to simplify and make cheaper manufacturing process and ensures the formation of dispersion strengthened heat-resistant material with a sub -,/ microcrystalline structure type basis, which results in a significant improvement of the complex of physical and mechanical properties and performance properties of chromium bronze. 

Processes of high-speed shaping change and especially high-speed hot extrusion create efficient conditions for treatment of low plastic and difficult-to-form materials which are widely used in tool making production. Due to the fact that high-speed stamping provides accurate billets with increased mechanical properties, it can be used as a technological process for manufacturing rod parts of die tooling operating under the increased loads and high wear. The purpose of the paper is to carry out experimental investigation of the possibility to obtain bimetallic rod stamping tooling by high-speed hot extrusion in high-temperature mode treatment in order to save die steels and improve the quality of the products obtained.

Dependences of micro-hardness distribution have been established outbound two steel contact plane in the zone of connection that are characterized by a minimum micro-hardness value in the connection joint. Availability of more plastic zone in the contact plane contributes to reduction of residual stresses due to their relaxation in this zone and higher joint strength.

The increase of efficiency of modification process for ductile iron is topically, thereby increasing its mechanical and operational properties. For these purposes, in practice, various magnesium containing alloys are used, including «heavy» ones on the basis of Copper and Nickel. The analysis has shown that the application of bulk inoculating alloys based on copper basis were not effectively due to long dissolution period. From this point of view, the interest is high-speed casting, allowing the production of inoculating alloys in the form of strips – chips that are characterized by a low dissolution time and low piroeffekt. The aim of this work is to study the features of structure formation in nodular cast iron using different spheroidizing alloys based on copper. Studies have shown that the transition from the use of briquetted form alloys based on copper and magnesium to the «chips-inoculating alloys» allowed increasing the efficiency of the spheroidizing process. Further improvement in the quality of ductile iron can be achieved by the use in «chip-inoculating alloys» additives of nanosized yttrium oxide powder.
