“…However, such information on cast iron CHYU22SH is virtually non-existent. In (Kovalevich, 1991, Zhuravlev, 1981 writing indicates that the specific heat of aluminum castiron type CHYU22SH at normal temperature is lower than that of gray and ductile cast irons, with increasing temperature as the thermal conductivity of aluminum iron increases at a time when the undoped iron is reduced (Ten, 2015). Therefore, at high temperatures (900 -1000 °C) a superior thermal conductivity CHYU22SH GCI (gray cast iron) and HCING (high-strength cast iron with nodular graphite) are produced (Kumanin, 1976).…”

Highly alloyed alloys, in which expensive chromium and nickel are alloying elements, are widely used as heat-resistant materials. Their total content in heat-resistant alloys reaches 30% or more. However, the life of working parts made of heat-resistant alloys is limited. Moreover, the higher the operating temperature, the shorter it is. This leads to increased costs for maintaining the units in working condition. Examples of such parts are the grate of agglomeration machines, details of boiler plants, roasting, heating, and glass melting furnaces, casting molds, exhaust manifolds of forced automobile engines, etc. In this regard, reducing the cost of heatresistant products, while maintaining their operating characteristics and life, becomes very actuality. One of the promising options to solve it is to manufacture these parts made of high-alloyed heat-resistant aluminum cast iron CHYU22SH (CHYU22SH - standard cast iron). Castings made of cast iron CHYU22SH differ, first of all, by being heat resistance at high temperatures in air (up to 1100°C) and in media containing sulfur, sulfur dioxide, oxides of vanadium, and water vapor. In addition, they can functionally operate as a wear-resistant product having high strength at normal and elevated temperatures. The paper presents the thermal and mechanical properties of casting, as well as the results of microstructure analysis of aluminum cast irons. The results of analyses and tests show that cast iron CHYU22SH can be obtained by casting with long walls of a thickness of 4 mm without external and internal defects. By doing so the castings have a uniform structure, high and stable mechanical properties, as well as lower by ~17-24% weight than similar cast of gray iron. The results of experimental - industrial testing laboratory studies confirm the influence of solidification conditions on the parameters of the structure of cast iron CHYU22SH.

“…At the same time, the global scientific society accumulated substantial laboratorial and industrial experience in different aspects of the Hadfield steel examination. The most research works were concentrated on the problems of quality improvement of castings [5][6][7], material strengthening [8][9][10][11], study of corresponding wearing mechanisms [12][13][14][15], optimization of technological processes in order to decrease production cost [16,17].…”

This study is devoted to influence of the temperature procedures of high-manganese austenite steel casting on formation of the internal structure and properties of castings. An example of a high-manganese austenite steel Fe-1.1C-16Mn-0.8Si-1.3Cr-Mo-Ni is considered, which differs from the generally accepted composition of Hadfield steel (110G13L) by an expanded Mn content and combined alloying with carbide-forming elements. The study applied an approach to choosing the optimal casting temperature, which is implemented using pre-computer modeling of the cast structure by the Cellular Automaton Finite Element method, followed by verification on physical samples. An analysis of the microstructure of the experimental samples obtained at the selected casting temperatures indicates the accuracy of conducted calculation: the discrepancy between grain sizes does not exceed 5 μm (4.4 %). Rational temperature contributes to formation of more fine microstructure and, accordingly, a high level of mechanical properties: pouring the alloy under study at 1390-1410 °C makes it possible to obtain an average grain size of 113-116 μm, minimal mass loss upon contact with the abrasive (1.74-1.81 %) and increased impact strength (28.5-28.3 kgf•m/cm 2 ). Subsequent approximation of the calculated values and obtaining a regression equation using the Reduced Major Axis method allows in practice to predict reliably (with determination coefficient 0.826) the grain size of the casting at the selected casting temperature without using additional software.

Effect of Out-of-Furnace Treatment on the Structure and Mechanical Properties of Steel 110G13l

Abstract: The effect of out-of-furnace treatment on the structure and properties of high-manganese steel 110G13L in cast condition and after a heat treatment (quenching) is studied. Data for two variants of out-of-furnace treatment (standard and experimental) are compared.
