| Summary: | (63.43'). Hardness and resistivity measured across a billet 6063, copper I 10, and filamentary Cu/NbTi composite billet in order to record the flow of the metal throughout an depth of the surface affected zone, and comparison of the determined to be less than 12% of the billet width. The distortion with first order calculations. Several testing ECAE extrusion. An aluminum billet with brass wire inserts effects of equal channel angular extrusion (ECAE) on aluminum extruded one pass through ECAE vary by less than 1%. The extrusions. Electrical resistivity measurements were used to Hardness measurements were used to measure the level of magnitude of the experimental strain and the angle of element measure strain uniformity throughout the workpiece after ECAE measured to be 63.63'. This compares well with theory monitor the level of strain throughout the billet. The angle of shear of a material element after a single extrusion is of the billet height. oriented perpendicular to the extrusion direction were used plastic deformation. Square grids were scribed on a split procedures have been used throughout this research project. processing. Other objectives include the determination of superconductor. The major objective of this study is to surface affected zone along the bottom of a billet is The objective of this work is to characterize the processing the size and width of the shear zone, determination of the to show the deformation of material through multiple width of the shear zone varied from one-tenth to three-tenths |
