<p>Joining aluminum wires into a fully dense billet without prior surface preparation is challenging, as surface oxides can prevent proper bonding. This study examines the potential of the Equal Channel Angular Pressing (ECAP) process to achieve full consolidation of aluminum wires into a single, dense billet without any surface oxide cleaning. Initially, wires were compacted into a cylindrical shape without surface preparation and then subjected to equal channel angular pressing through four passes at room temperature. Micro-hardness measurements were conducted using a Vickers micro-hardness tester at five distinct locations, and the average grain size was evaluated through optical microscopy and scanning electron microscopy analysis. Density findings revealed complete wire joining and compression tests showed the yield stress increased approximately 2.5 times after the fourth pass. Ultimately, the process resulted in a fully dense material, accompanied by progressive grain refinement and increased micro-hardness with each pass, especially in regions near the channel angle vicinity.</p>
