Abstract

We have developed a integrated computational method in order to solve the Zener-Hollomon equation. This method solves the fitting problem of the equation of Zener-Hollomon for wide ranges of applied stress, strain rate and work temperature by means of the progressive application of three algoritms kinds.In first place a program, by means of a reiterated linear regression by planes, it allow to get some values that will be later the initials values of a second block of algoritms and it permit also purify the experimental data set. The second block of algoritms carries out an fitting by nonlinear least squares using a variation of the of modified Gauss-Newton method. In third place is chained a group of programs that they permit iterate starting of the solution of the pr
