Investigation of White Alloyed Cast Iron Ductility

It is shown that during hot plastic deformation of cast iron a decisive role is played by its ductility at temperatures of deformation. There is used a method of active experiment mathematic planning to reveal dependences between a chemical composition of white alloyed cast iron and its ductility. It is defined that at the adopted intervals of variation carbon, nickel, manganese, titanium and boron contribute to ductility increase, and chromium and molybdenum promote to its decrease.
