“…In order to verify the phase formed at these sharp exothermic peaks, XRD experiments were carried out on the tested DSC samples. Results indicated that these sharp exothermic peaks were due to the forming of Ti 3 SiC 2 (for the sake of simplicity, diffraction pattern is not showed here); this is consistent with the results reported in literatures [8,[12][13][14]. From the above results, it can be seen that Ti 3 SiC 2 can be formed rapidly when the temperature reached at 1400 ℃ and the forming temperature decreased noticeably with the increase in the initial Si content.…”

Ti3SiC2 is a bioinert material. The combination of high fracture toughness, excellent corrosion resistance and easy machinability make it a new class of potential biomaterials for orthopedic applications, dental implants, and fixation devices for the bone. In this paper, effect of Si concentration on the sintering of Ti3SiC2 bulk material was reported. Ti3SiC2 bulks were fabricated by pressureless reactive sintering of powder compacts made of Ti, Si and graphite powders. Nearly pure Ti3SiC2 bulk was obtained by reactive sintering of the powder compact, with a nominal composition of 3:1.1:2 in molar ratio of Ti:Si:C, at 1500 °C for 120 minutes. TiC, a non-preferable impurity was avoided by the appropriate addition of excess Si (relative to stoichiometric composition of 3:1:2 in Ti3SiC2). However, too much Si will result in the formation of significant amount of TiSi2 and SiC in the sintered Ti3SiC2. Microstructure of the prepared Ti3SiC2 bulks was analyzed by scanning electron microscope. Phase constituent analysis was carried out by x-ray diffraction. Effect of Si content on the density of sintered samples was also studied.

“…They reported the reactions of L + TiC x = β Ti + Ti 5 Si 3 C x and L + TiC x = Ti 5 Si 3 C x would happen at 1354 °C and 2406 °C, respectively. At the Ti-C side, the exothermic reaction Ti + C = TiC would happen above 870°C [20]. The following equation was used to calculate the volume fractions of the individual phases [21]: ...…”

TiC/Ti5Si3composite materials on Ti-5Al-2.5Sn were in-situ synthesized by argon tungsten-arc welding (GTAW) deposition from powder compacts with the molar ratio of Ti:Si:C=3:1:2. X-ray diffraction (XRD) techniques and scanning electron microscope (SEM) were employed to characterize the microstructure of the composites. The effects of depositing times on the surface microstructure of the tracks deposited were studied. From the products synthesized in this work, the content of TiC/Ti5Si3in-situ composites on the surface of the tracks differed from each other by depositing one, two, three, and four times, respectively. The minimum impurities were obtained and the distribution of TiC/Ti5Si3. In-situ composites were most homogeneous in the track surface by depositing three times.
