Selection of optimal Al-Si combinations in cast iron for castings for engineering purposes

the tensile strength model: y=17+13.7·x1–4.5·x2–4·(x1)2–1.6·(x2)2–x1·x2

based on the data obtained, it is possible to establish the average composition of the alloy for Al and Si in serial smelting and its location relative to the optimal curve Si=f(Al)

possible to choose the amount of correcting additives depending on the actual indicators of the chemical composition during the melting process

there has been no practical validation of the results of the research
