X-ray diffraction analysis reveals no Received in revised form 28 February 2012 Al–W intermetallics in the composites. The microstructure of the composites shows excellent W particle Accepted 28 March 2012 distribution in the matrixes. Tensile, hardness, and electrical conductance properties of the composites Available online 6 April 2012 are determined. The results show that the introduction of 4.2 vol% W particles to Al matrix via ARB process leads to significantly enhanced mechanical properties and excellent electrical conductivity.
