“…To obtain samples that meet the above requirements, the powder crushing process has been used in order to get an even distribution where a solid sample will be obtained. The ignition temperature of SHS-process was around 900±120℃ and then increased during the SHS process up to 1100±20℃ for the used powders content [11,12]. When the refining process is carried out the distribution of the powder is uniform and afterward, we can obtain a solid sample.…”

In the present paper, Ti/SiC composite materials have been fabricated by using Selfpropagating high temperatures synthesis (SHS). SHS is a well-known method for fabrication of the advanced materials in a single step process and is based on a system that involves an exothermic combustion. Titanium powder (Ti/p) with average particle size 100 µm and Silicon carbide (SiC) with 100-320 µm particle size range has been mechanically activated by attrition mill. Powder weighing has been prepared in accordance to the size of each volume fraction where the ratios for Ti/SiC are 70:30% and 60:40%. The optimal density results were achieved in the volume fraction of 70:30% at 1000º C for 4.54 gr/cm 3 . The porosity test data has shown that the porosity value has been increased during the increasement of the SHS sintering temperature. The lowest porosity was produced at a volume fraction of 70:30% in a sintering temperature at 900º C with the corresponding value 2.36%. The highest and lowest hardness value varied from 194 HV to 40 HV. The results have shown that mechanical properties of the Ti/SiC composite materials have been increased in comparison to the commercially pure titanium substrate and almost close to mechanical properties of Al/SiC composite materials.

“…Hardness testing and Scanning Electron Microscope (SEM) tracing were carried out. The obtained results of Ti/SiC by using SHS method have been compared with the other composite materials by using the same SHS method [11]. Research on Ti/SiC enhancement has been based on Metal Matrix Composite (MMC) [12].…”

Composite materials were applied to meet the demands of production efficiency on industrial because they offered the superior properties both of aspects on mechanical and physical properties were constantly being refined and developed with several methods. Composite technology with aluminum as a matrix as well as ceramic materials as reinforcement was very dependent on a result of the perfection of the manufacturing process on the matrix material and reinforcement was used. Aluminum currently still dominates as a matrix because of its ductility, while reinforcing materials that are widely used are ceramic elements such as silicon carbide (SiC) and alumina (Al2O3). Using of SiC/Al2O3 has been widely studied because of the remarkable improvement of the mechanical properties it produces. The addition of number of SiC particles to Al2O3 was able to significantly increase the hardness properties. In this study, a number of composite manufacturing methods were compared from the results of properties by accumulative press bonding (APB), accumulative roll bonding (ARB), and repetitive press roll forming (RPRF). The mechanical properties of RPRF results are known to produce better properties, especially mechanical properties. Mechanical properties were observed from tensile and hardness tests. The finer grain size is produced by increasing the compression cycle and increasing the mechanical properties when adding double reinforcement of the SiC/Al2O3, which causes the strength and hardness of the RPRF results to increase. Whereas other methods such as APB and ARB it is not compatible with composite materials, this proves that the RPRF method was very suitable for processing composite materials compared to APB and ARB methods.
