Fabrication and Microstructure of Al-Based Hybrid Composite Reinforced by B4C and Ultra-Dispersed Tungsten

Abstract:

Article Preview

Al-based hybrid composite reinforced by ultra-dispersed tungsten and B4C, was produced by mechanical alloying and hot extrusion. Structure of obtained composites was studied by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The compressive and tensile properties of these materials were investigated. Tribological tests showed high antifriction properties and wear resistance of composite containing B4C and tungsten. The dilatometric measurements showed that thermal expansion coefficient remains approximately constant up to 500 °C.
