“…The Al-Cu-Mg alloy system has more density than pure Al. Therefore, the homogeneous dispersion of reinforcing particles is more difficult to achieve when using the traditional casting method [11,17]. Thus, this research aims to investigate the effects of tungsten carbide (WC) particles on the tribological behavior of an Al-4Cu-1.5Mg (wt.…”

Different Al–4Cu–1.5Mg/WC composites were synthesized through powder metallurgy to establish the effect of WC particle addition on the abrasive wear behavior of an Al–4Cu–1.5Mg (wt. %) alloy. The wear tests were performed using a pin-on-disc tribometer at room temperature in dry conditions using SiC abrasive sandpaper as a counterbody and tribometer of linear configuration. The results showed that WC additions increase the hardness of the Al–4Cu–1.5Mg alloy due to the strengthening effect of particle dispersion in the aluminum matrix, which generates an improvement in the wear resistance of the composites by preventing direct contact of the sample with the counterbody, in turn delaying the plastic deformation phenomena responsible for the degradation sequence. In addition, the dominant wear mechanism was abrasive wear, and the increased friction coefficient did not bring a rapid wear rate, which was related to the enhanced deformation resistance due to the high hardness.

The present work reports on the mechanism of formation of TiC in pure Aluminium melt. A halide salt of Al 3 TiF 6 , graphite powder and pure Al were used to prepare in situ Al-TiC Metal Matrix Composites (MMCs). Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) were used to determine the microstructural characteristics of the composite. XRD was further used to determine the phases involved in the composite for confirming the formation of TiC. Further to assess the mechanism involved in the in situ reactions, DTA/TGA thermograms were used to analyze the reactions between molten Al, halide salt and graphite powder. Tensile tests were conducted to study the fracture behavior of the in situ prepared MMCs.

Todays composite material have gained more popularity due to their improved properties over the conventional materials. In the present paper, insitu composites were fabricated via chemical reaction between molten aluminium alloy and halide salt KBF4 with cryolite at 8000C by stir casting method. The microstructures of the composite containing 3 and 5 wt. % of AlB2 reinforcement phase have been compared with the unreinforced aluminium alloy. The microstructure analysis shows clean AlB2 particles uniformly distributed throughout the matrix. With the increase in the AlB2 reinforcement, insitu composite show less agglomeration and recovery of boron is more when compared to the unmixed halide salt in the fabrication of inistu composite
