Determination of processing conditions of 1420 alloy of Al-Mg-Li system by applied temperature analysis

Abstract

The design of airplanes and spacecraft of the new era requires the creation of materials that will be distinguished by lightness, increased strength and load capacity. When determining the processing parameters, the method of applied temperature analysis turned out to be useful and effective, the optimization of the composition and structure was greatly simplified, as well as the very transformation of the obtained experimental data into a ready-made digital form. Thanks to the method of applied temperature analysis, by linking to the periodicity of discrete states, the accuracy of determining the processing conditions of alloy 1420 of the Al-Mg-Li system is increased. The number of rolling passes can be reduced if, in addition to the data of forces, rolling speed, changes in sheet thickness, control of the dynamics of cracking is included. To perform the decomposition of the continuous deformation process of the blanks by scanning through the crack formation elements relative to the temperature axis in agreement with the determination of the sample size change data.
