Abstract

Ridge analysis is used to investigate the response surface describing the mathematical model of the influence of the Al / Mg ratio and temperature on the Al-Mg alloy castability during the low-pressure casting. It is shown that the suboptimal values of the technological regimes ensuring the maximum castability values of the Al-Mg alloy can be determined taking into account the limitations imposed on the technological process on the basis of a mathematical model constructed by implementing a second order central orthogonal composite design (COCD)
