Fabrication and optimization process of mechanical properties of MoSi2 composites reinforced by carbon nanotubes (CNT) using Taguchi method

This experimental research aims to produce and study the properties of MoSi2 reinforced with CNT composites using the SPS sintering method. First and before any laboratory operations, using the Minitab 14 software, experimental samples were designed under L16 arrays. Four levels were set for defining parameters, such as the amount of reinforcing phase (CNT), sintering temperature (degrees C), and holding time (T). XRD, FESEM, density, micro-hardness, bending strength, and fracture toughness tests were used in the study for in-depth investigations. According to the signal-to-noise analysis, the parameter with the greatest influence is the reinforcement rate. Based on the obtained results, the composite with 5 wt% of carbon nanotubes, a sintering temperature of 1300 degrees C, and a holding time of 10 min was found to have the highest results.
