| The Mg-SiC nanocomposite specimens were produced at low strain rate of 8×10−3s−1 using a universal INSTRON testing machine, strain rate of about 8×102s−1 using a drop hammer and at strain rate of about 1.6×103s−1 employing a Split Hopkinson Pressure Bar (SHPB). Tribological behavior of the samples was investigated in this work. The compaction process was performed at the temperature of 723K. The results showed increase in the wear resistance as the nano reinforcement increased. The results also indicated that as the reinforcement content increased to 10 vol%, the weight loss reduced approximately by 63%, 58%, and 35% for the samples fabricated by SHPB, drop hammer, and quasi-static hot pressing, respectively. The results also suggested that the wear rate of samples fabricated by SHPB was nearly 40% lower than that for quasi-statically fabricated samples and non-reinforced samples. | ||
