Some aspects about the mathematical modelling results of an S.G. cast iron with special properties

The paper contains a study about computer use in graphical and mathematical processing of the results of some researchers about Ni–Cu–Cr alloyed, ferrito-bainitic, S.G. cast iron. It is pointed out that the influence of some metallurgical factors on the phase transformation and properties in the studied cast iron. The results of the mechanical properties of an S.G. cast iron were determined a mathematical modelling concerning to calculate the regression equation with the help of computer which assure rapid and efficient solution. It was determinate the coefficients of linear and polynomial mathematical regression.
