“…In the liquid state process, spray deposition, squeeze, and stir casting fabrication techniques are commonly utilised to produce MMCs.The fabrication methods of metal matrix composites play a very important role in the enhancement of mechanical properties. In conventional fabrication methods, problems such as poor wettability, uneven dispersion of particles, and porosity have been degrading the performance of MMCs [18][19][20][21][22]. Therefore, to avoid such issues and to attain homogeneous dispersion in the fabricated MMCs, squeeze casting technique can be preferred in this research.…”

Aim of the present work focuses with influence of processing parameters on fabricated composites of LM25 alloy with SiC particles reinforcement through the squeeze casting technique. The following process parameters like stirring speed from 550 to 750 rpm, SiC weight proportions from 4 to 8% and melting temperature from 600 to 700oC were employed. Then processed composites were subjected to microstructural analysis and mechanical tests to ascertain metallurgical and mechanical properties. SEM and EDS results confirmed that the better bonding of SiC particles with matrix is achieved in the LM 25 composites and it is due to homogeneous dispersion of SiC particles in the stir casting process. The maximum tensile strength (211 MPa) and hardness (91 Hv) is achieved on the composite samples with processing parameters of 750 rpm stirring speed, 8% of SiC proportions and 650 0C of melting temperature, respectively. From the design of experiment by Taguchi method, it is found that the stirring speed plays an important role in achieving better distribution of SiC particles in the composite samples than that of other parameters like SiC weight ratios and melting temperature of the alloy.

In order to achieve the goal of lightening the braking system of urban rail trains, SiCp/ZL101 and ZL101 plates were welded by friction stir lap welding (FSLW) to prepare a new type of brake disc material. The friction and wear properties of the friction-stir-processed composite material were studied at different temperatures (30 °C, 100 °C, 150 °C, 200 °C, 250 °C, 300 °C) to provide a theoretical basis for the evaluation of braking performance. The experimental results showed that the sliding friction processes at each temperature were relatively stable, the friction coefficients did not vary much and the average friction coefficients changed slightly, stabilizing at about 0.4. The wear extent and the depth of wear scars increased with the increase in the temperature, reaching the highest at 150 °C and then began to decrease. At room temperature, the wear forms were mainly oxidative wear and abrasive wear; as the temperature rose, under the cyclic shearing action of the grinding ball, the abrasive debris fell off under the expansion of fatigue cracks and fatigue wear was the main form at this stage. When the temperature reached 200 °C, it began to show the characteristics of adhesive wear; after 250 °C, due to the gradual formation of a mechanical mixed layer containing more SiC particles and oxides on the wear surface, it exhibited high-temperature lubrication characteristics, and the wear extent was equivalent to 35% of the wear extent at normal temperature, indicating that the composite material had good high-temperature friction and wear properties.
