Analysis of the dependence of the mechanical properties of HSLA steels of hot rolling temperature and deformation parameters

The paper discusses the basic techniques of statistical analysis of experimental data. Based on the criteria of probability and mathematical statistics, regression models were constructed dependences of mechanical characteristics (yield strength, tensile strength and percentage reduction) on the temperature of the end of hot deformation. An assessment of the adequacy of the obtained models by the method of residues. But the basis of the models used to explore the dependence of mechanical properties on the temperature of the end of hot deformation and performed their analysis.
