| Popis: | Metal matrix composites are an essential product used in engineering materials. This product has wide applications in automotive, aerospace, and other uses because of their lower density, good specific strength, best machinability, and better mechanical properties compared to Al 6063 alloy. In this paper, four different reinforced such as (MA), (MCA), (NFC) and (SA) with a constant rate of 5 wt.% for each reinforced element used and mixed with Al 6063 alloy as a metal matrix composite by using modified two-step mechanical stirrer and having three blades at each step. Coated carbide tool insert was carrying out the turning process. Surface roughness measured after turning of every change in cutting speed. Average chip length and its shape style formation performed within cutting speeds of 10 and 90 m/min, which appears in different length and shapes. Mechanical properties, damping characteristics, and wear loss improved dramatically by adding all reinforced composites to the base Al 6063 alloys. As the results of experiments, the surface roughness decreased by adding all four types of reinforcements. The mechanical properties, wear loss and damping characteristics improved by the constituents of all kinds of reinforcements and also by mixing of all types of constituents together. The effects of MA and NFC are more compared to MCA and SA for improving all conditions of experimental results. Microstructure observation produces compact grain boundaries with strong grains of metal matrix composites compared to Al 6063 alloys. |
