MECHANICAL PROPERTIES OF PRODUCT FROM 7075 ALUMINUM CHIPS AFTER CONSOLIDATION BY KOBO METHOD
Keywords:metallic chips, KoBo method, extrusion, mechanical properties of extrudate
This paper presents the possibility of consolidating side products of turning of aluminum alloys into the form and properties of solids metals using low-temperature KoBo extrusion method has been assessed.The proposed method is based on cold compaction of chips into briquettes, and then extrusion by KoBo method at room temperature. The extruded wires were tested for mechanical properties (uniaxial tensile test and Vickers hardness test), and compared with specific mechanical properties of solid material. A very good effect of chips compaction has been proved by KoBo method, which has been confirmed by relatively slightly different mechanical properties of the material after consolidation compared with the solid one.
