摘要：

In the present study AZ91 matrix composite with B4C reinforcement was fabricated by friction stir processing (FSP). In addition to grain refinement of AZ91, the B4C particles resulted in improved wear resistance and microhardness. Study comprises of composite fabrication by FSP under natural cooling. The specimens were characterized by Optical Microscopy and Scanning Electron Microscopy (SEM) with Energy Dispersive Spectroscopy (EDS). Wear, the tribological property, was studied on pin-on-disc apparatus and results have confirmed the property enhancement. The wear test has been carried out at 1m/s sliding velocity at 5N normal load for FSPed and as cast specimens at sliding distance of 2000m. Further analysis has revealed that microhardness and wear resistance improve as the B4C particle size was increased from sub microns to 50 mu m. (c) 2018 Elsevier Ltd. All rights reserved.
