In this work, the microstructure and mechanical properties of titanium matrix composites were tuned by introducing graphene and alloying elements. The titanium matrix composites reinforced by graphene oxide (GO) and cobalt elements (GO@ Co/TA1) are synthesized by the spark plasma sintering (SPS) technique. Results show that the precipitated Ti2Co phase is almost reticulate distributed in the tissue, while the in situ TiC particles are discontinuously distributed at the grain boundaries. The ultimate tensile strength and yield strength of GO@ Co/TA1 composites are 160% and 126% higher than those of pure TA1, respectively. In addition, composites show excellent ductility where the elongation of GO@Co/TA1 is around 10.95%. Therefore, such enhanced mechanical properties can be attributed to the synergistic strengthening effect of interfacial‐distributed TiC particles and intragranular‐distributed intermetallic compounds (Ti2Co), which would provide a new idea for the design of metal matrix composite.

“…Increases in powder activity accelerate the mutual diffusion of atoms. Under certain conditions, alloy phase nuclei are formed through ball milling and gradually grow into an alloy phase until all elemental powders are consumed (Dai et al, 2013;Maat et al, 2018;Sadeghi et al, 2018).…”

Ultrafine tungsten carbide (WC) powder refers to WC powders with a particle size between 100 and 500 nm. Researchers have improved the comprehensive properties of WC-based cemented carbides by preparing ultra-fine WC powders. Because of the preparation and application of nanoscale WC powders, ultrafine-grain cemented carbides with excellent hardness and wear resistance have been successfully produced. In this paper, the preparation methods of ultra-fine WC powder are divided into solid-phase, liquid-phase, and vapor-phase methods according to the state of the raw materials (i.e., the W or C source). The liquid-phase methods could realize the preparation of WC at the temperature between 500 and 800 • C. The purity of WC prepared by vapor-phase method is the highest. The solid-phase reduction carbonization method has potential industrial application.

“…Analysis of materials structure containing long-range order of crystals is a sort of a routine process. Nowadays there is a diversity of techniques which is being utilized for prediction of crystalline structures such as transmission electron microscopy (TEM), X-ray diffractometry (XRD) and so on [1][2][3][4]. Nevertheless, extraction of data is still in a serious doubt for the amorphous structures due to the short-range order of crystals distributed stochastically in the bulk of samples.…”

In this study, the structural chemistry of Fe3+ doped Li2O–Al2O3–SiO2–TiO2 (LAST) glasses has been analyzed utilizing UV-Vis spectroscopy. Optical parameters like absorption and extinction coefficients, indirect and direct optical band gaps, Urbach energy as well as Fermi energy level of samples were estimated via their absorption spectra. Then, it was tried to make a relationship between the variation of mentioned parameters and structural chemistry of different doped samples. Results of the investigation illustrated that even a little change in the microstructure of glassy samples has an effect on optical parameters and accordingly it could be sensible. Furthermore, it was revealed that Fe3+ ions have the role of network forming in the structure of glass by increasing the formation of bridging oxygens (BOs) in the matrix.
