Identification of regularities of the influence of titanium on the impact toughness of hypoeutectic wear-resistant cast iron and assessment of the efficiency of its additional alloying with boron

The object of the research: Wear-resistant cast iron used for parts with operational requirements dictated by conditions of intense friction and impact loads. Investigated problem: selection of a rational option for alloying cast iron to meet specified wear resistance requirements. The main scientific results: a mathematical model has been constructed that allows identifying patterns in the behavior of impact toughness of wear-resistant cast iron depending on the carbon content and carbon equivalent at different levels of titanium alloying. The area of practical use of the results of the study: the results obtained can be used in industrial conditions when smelting cast iron for parts that experience friction and impact loads during operation. Innovative technological product: rational options for alloying wear-resistant cast iron that meet specified impact toughness requirements. The scope of the innovative technological product: cast machine parts operated under conditions of intense friction and impact loads.
