About the method1. The general achievements of the author in the field of material science and technology serving him are set out in SCIENTIFI AND APPLIED2. Key features characterizing the numerical approach in determining the influence of the alloying elements on the complex of properties of theinvestigated alloys have been transposed into the SUMMARY OF THE OPTIMIZATION OF CHEMICAL COMPOSITION IN THE FIELD OFMATERIAL SCI ENCE. This method explores databases of iron magnesium and titanium alloys. For all alloys, Tacuchi's method of qualitymanagement has been successfully applied.3. A full description of the approach with all the details of its implementation is contained in the monograph of the German academic publishing houseLambert. The topic of the monograph is MATERIALS SCIENCE, EFFECTIVE SOLUTIONS AND TECHNOLOGICAL VARIANTS.
