Experimental Determination of Force and Deformation Stress in Nanostructuring Aluminum by Multiaxial Forging Method

Abstract

This Paper Aims to Determine by Experiment Total Force and Stress of Deformation Depending on Punch Stroke and the Level of Deformation on Severe Plastic Deformation of Aluminum by Multiaxial Cold Forging. the Deformation Force in Multiaxial Forging Depends on a Number of Parameters of whom the most Important are: Strain, the Flow Force of Aluminum, Deformation Speed, the Friction between the Material and the Die, Shape and Size of Die, the Dimensions of Deform Profile, Shape and Dimensions of Workpiece, Temperature Variation during the Process, Physical and Mechanical Properties of the Workpiece Material, the Structural Inhomogeneity of Workpiece Material. the Deformation Process is Discontinuous and Includes Deformation Processes that Define a Cycle of Severe Plastic Deformation. this Paper Aims to Determine the Force and Stress Corresponding to the First 12 Cycles of Severe Plastic Deformation.
