Özet
In this study, Al matrix composites reinforced by the high amount of NiAl (40%) were produced by the pressure infiltration method. Commercially AA1050 (99.59 %) was used as matrix material and NiAl (at. 1:1) particles were used as reinforcement. Also, a small amount of Mo (wt. 2%) was added into NiAl for a better matrix-particle interface and to increase the mechanical properties. The proportion of particles was kept constant, and their sizes were changed from 45 to 125 mu m. The microstructures were examined by SEM, and formed phases were determined by EDS and XRD analysis. Mechanical properties and wear behavior were determined by compression, hardness, and abrasion tests. As a result of these tests, it was determined that composites were produced successfully. It was determined that compressive strength increased with decreasing particle size. And also, small particle size composites showed higher wear resistance.
