Composite materials by definition are a combination of two or more materials. Although the idea of combining two or more components to produce materials with controlled properties has been known and used from time immemorial, modern composites were developed only several decades ago and have found by now intensive application in different fields of engineering (Vasiliev&Morozov, 2001). These ma...

Nanostructured Al composites with 2.5 wt.% aluminum nitride (AlN) were fabricated by powder metallurgy using mechanically milled aluminum powder mixed in a planetary ball mill with different particle sizes of AlN (50 nm and 1 μm) as reinforcement. After 20 h milling, the powders were die-pressed uniaxially in a steel die and then sintered at 670 °C for 2 h. The morphologies and properties of th...

In this study, Al/Gr composites with 5,10,15,20 weight percent of graphite were produced by in-situ powder metallurgy method. The produced powder mixtures were consolidated and sintered at optimum conditions. The resultant composites were solution treated at 495?C and aged at 170?C. The influence of graphite content on the bending strength of composites was studied. The distribution of graphite...
