IMPROVED METHOD AND SOFTWARE PROGRAM FOR DETERMINING THE REFINED CONSTANTS OF FORMULAS FOR CALCULATING THERMOKINETIC PARAMETERS FOR GROUPS OF STEEL GRADES
An improved method and a software program for calculating the refined constants of formulas that determine the thermokinetic parameters in the theory of calculating the metal flow stress, considering the processes of dynamic transformation of its structure during hot plastic deformation, both for individual steel grades and for groups (up to 25 steel grades). The calculation of the refined constants of formulas determining the thermokinetic parameters for groups of two steel grades: 0,5 S - 0,2Si - 0,68Mn, 0,06S - 0,12Si - 0,42Mn and three steel grades: 45, 08, 55. At the same time, the average relative deviations of the calculated values of metal flow stress in relation to the experimental ones were 4-10 %.
