The paper deals with a theoretical and experimental study of the relationship between the microstructural parameters. mechanical properties. and impact deformation and fracture of steels using the example of 17Mn1Si pipe steel. A model for the behavior of a polycrystalline grain conglomerate under impact loading at different temperatures was proposed within a cellular automata framework. https://poolsproductscanadas.shop/product-category/pentair-triton-c-parts/
