“…Some features of the ignition and combustion mechanisms in aluminium-based reactive materials were considered in a recent review [217]. Theoretical investigation of the intermetallics formed by synthesis from elements involves traditional modelling using differential equations of heat and mass transfer [218], phase-field modelling [219] and molecular dynamic simulations [220][221][222][223][224][225][226][227][228]. The latter method is undergoing fast growth today due to the promising application to design of nanostructured materials.…”

Self-propagating high-temperature synthesis (SHS) or combustion synthesis (CS) is a rapidly developing research area. SHS materials are being used in various fields, including mechanical and chemical engineering, medical and bioscience, aerospace and nuclear industries. The goal of the present paper is to provide a comprehensive state-of-the-art review and to analyse a critical mass of knowledge in the field of SHS materials and coatings. We also briefly discuss the history and scientific foundations of SHS along with an overview of the technological aspects for synthesis of different materials, including powders, ceramics, metal-ceramics, intermetallides, and composite materials. Application of CS in the field of surface engineering is also discussed focusing on two main routes for applying SHS to coating deposition: (i) single-step formation of the desired coatings and (ii) use of SHSderived powders, targets or electrodes in the coating deposition processes.

“…And combustion synthesis is being used to produce ceramics, intermetallics, and composite materials (Ref [9][10][11][12]. By the application of this technology, joining a ductile metal with a brittle ceramic composite matrix has considerable potential for substantial improvements in fracture toughness (Ref [13][14][15].…”

The novel TiB 2 -TiC/42CrMo4-laminated composite materials were successfully fabricated by combustion synthesis in different high-gravity fields. This ceramic/metal composite material possesses continuously graded composition, and multilevel gradient microstructure, which is composed of TiB 2 -TiC ceramic substrate, ceramic-based intermediate layer, metal-based intermediate layer, and 42CrMo4 substrate. The ceramic-based intermediate layer is the main gradient transition region in the joint which shows that the TiB 2 and TiC grains decrease gradually in size and volume fraction from the ceramic substrate to metal substrate. The experiment reveals that the increased high-gravity field not only leads to the higher combustion temperature and the remarkable thermal explosion mode, but also attributes to the enhanced interdiffusion and convection between the molten steel surface and liquid TiB 2 -based ceramic. So, the reliable fusion bonding of TiB 2 -TiC/42CrMo4 composite materials is achieved. Moreover, the phase separation and forced filling effect of high-gravity field is the key to improve the densification and bond performance of the joint. The ceramic/metal joint in the continuous gradient composition and microstructure represents not only the transitional change of Vickers hardness, but also the high shear bond strength of 420 ± 25 MPa.

“…NiTi shape memory compounds are being used in a variety of medical and engineering purposes owing to unique shape memory effect (SME) and superior superelasticity with excellent corrosion resistance, good biocompatibility and wear resistance. Shape memory behavior of this material is due to thermoelastic martensitic transformation from high temperature B2 (austenite) to low temperature B19′ (martensite) phase [1][2][3]. Shape memory materials are made by well-known methods related to melting and casting.…”

Nickel and Titanium elemental powders with a nominal composition Ni-50 at.%Ti were mechanical alloyed in a planetary high-energy ball mill in different milling conditions (5, 10, 20, 40 and 60 h). The investigation revealed that increasing milling time leads to a reduction in crystallite size, and after 60 h of milling, the Ti dissolved in Ni lattice and NiTi (B2) phase was obtained. With milling time, morphology of pre-alloyed powders changed from lamella to globular. Annealing of as-milled powders at 1173 K for 900 s led to formation of nanocrystalline NiTi (B19′), grain growth and release of internal strain. The results indicated that this technique is a powerful and high productive process for preparing NiTi intermetallic compound with nanocrystalline structure and appropriate morphology.
