Abstract :Composite materials are produced in different material structures depending on their production purposes. This study aimed to produce a circular profile material with partially preserved deformation capability while increasing its strength properties. The composite material was produced with double walls and the outer wall consisted of Al6061 and the inner wall consisted of Al2124-SiC metal matrix composite. Material variables were the variation of wall thicknesses and SiC reinforcement ratios. The materials were produced in 3 different wall configurations with inner and outer wall thicknesses of 1.5-0.5 mm, 1-1 mm, and 0.5-1.5 mm, respectively. SiC reinforcement ratios were determined as 3, 7, and 11%. The materials were produced by the extrusion method and extrusion variables such as temperature (500 ˚C) and die angle were kept constant. The produced materials were exposed to flattening tests. According to the test results, the flattening resistance of the materials increased with the SiC reinforcement in the inner layer and with the increase in the reinforcement ratio. This increase started to decrease at the 11% reinforcement rate. Likewise, the strength, which increased with the increase in the thickness of the inner wall, decreased as the inner wall reached its highest value. While the Al6061 material, which has a ductile structure, did not show any failure in full flattening, with the increasing inner wall thickness and SiC ratio, failures occurred in double-walled materials both in the lateral regions and at the material-jaw contact points.Keywords : Çift katmanlı boru, SiC, Ekstrüzyon, Yassıltma testi
