Research into the process of producing powder tapes

摘要

The present article is focused on the rolling of powder tapes. A mathematical model of rolling a powder core in a metal cover is developed based on splitting a consolidation zone into a final set of elementary volumes. The main computational approach is based on the joint solution of the condition of static balance of the elementary volume and the condition of plasticity of porous materials in tension in a final and differential form. During experimental studies, the influence of cover thickness on the course of rolling powder materials is established. Thus, the more cover thickness, the higher its rigidity and elastic deflection. It reduces the extent of the deformation center, power parameters of the process, and deformation of the powder component. Also, the parameters of physical-mechanical properties of powder materials which enter into a condition of plasticity for porous materials were investigated.
