Abstract
In work was researched the composition and structure of high-alloyed aluminum cast iron ЧЮ22Ш.Crystalization of cast iron ЧЮ22Ш (ЧЮ22Ш standard cast iron) was researched by phase transformation, leaking upon its harden and cooling -down.High-alloyed materials are widely applied as the heat-resistant materials.Overall content of that reaches 30-50% and more.Previous performed researches allowed to optimize the content high-alloyed aluminum cast iron ЧЮ22Ш, to research its structure, casting and operational characteristics, to develop technological mode of melting, casting and thermal / heat treatment casts, to held its industrial examination and to determine perspective direction of its application.However, in present time ability of the aluminum cast iron ЧЮ22Ш is being used not sufficiently. Keywords: heavily doped aluminum cast iron structure, the composition of the phases, thermal properties, specific heat, thermal conductivity, thermal diffusivityHigh-alloyed materials have been widely applied as the heat-resistant materials.Overall content of that reaches 30-50% and more.Therefore, the cost of heat-resistant alloys is very high.
