“…The combustion synthesis of the NiAl compound is usually considered to be ignited when the aluminium melting temperature (660uC) is reached. 8,9 The temperature values recorded in the test are close to the thermodynamic calculation (in Table 1) and the measured adiabatic temperature is close to the calculated one, so we can presume that the SHS reaction took place almost totally.…”

Self-propagating high temperature synthesis (SHS) is a process whereby reactants are ignited to spontaneously transform to products in an exothermic reaction. The aim of this study is to propose a method to join nickel aluminide with AISI 316 stainless steel by SHS and to study the combustion synthesis of nickel aluminide. From the heat of combustion synthesis junctions were formed between annular AISI 316 stainless steel and a powder metallurgy compact of Ni and Al blends. The Al mole ratio for testing the joining grade in the initial powder mixture varied from 25 at.-% to 40 at.-%. In order to check the sufficiency of the SHS reaction, the test temperature was compared with the thermodynamic calculation values. The metallographic analysis indicated that NiAl and Ni3Al were formed in the joint layer.

“…Non-electric welding is an innovative evolution from Self-propagating High-temperature Synthesis(SHS) welding. SHS welding utilizes the SHS reaction heat to join materials, and finds wide applications in joining refractory metals, ceramics and intermetallic compounds [2][3][4][5]. However, SHS welding typically requires a set of vacuum and high-pressure reaction furnace and heating apparatus, resulting in an operation inconvenience.…”

Non-electric welding is a novel efficient technique for emergency maintenance, which utilizes the heat released by combustion reaction to join metals without needing any power supply or gas sources. Welding experiments were performed with 45 steel as the weld object, and results showed that the weld metal jointed the weld object in a metallurgic connection with the tensile strength above 280 MPa, which proved non-electric welding a fusion welding technique. Non-electric welding technology has advantages of simple operation and good mechanical performance, therefore possesses a promising application prospect.

“…The influence of Pt content on the combustion synthesis of NiAl was studied upon variation in process parameters. The values previously optimized for the SHS build-up process [82,83] were taken as the starting point of this study. They were as follows: P Ar = 50 MPa, v h = 90 deg min -1 , G Ni = 10 µm, G Al = 30 µm, P comp = 50 MPa, m = 1 g. Nevertheless, because of platinum addition, alternative values were tested for v h = 50 deg min -1 , P comp = 100 MPa, and the compact weight m = 0.5 and 0.7 g. The average grain size of Pt was G Pt = 2 µm, and the tested values for platinum content were 5, 8, 12, and 18 at %.…”

International audienceBoth in situ TRXRD and IR thermography, on the one hand, and different levels of modeling, on the other, have generated a strong progress in the knowledge and control of numerous SHS reactions. The SHS of simple binary materials, such as intermetallics (FeAl, MoSi2, NbAl3, etc.), oxides (e.g. ZrO2), carbides (e.g. SiC) or nitrides, more complex materials, such as mullite, SiAlONs, MAX phases, composites (SiO2-Al2O3, NiAl-ZrO2), powders in their more complicated states, such as well controlled microstructures, fully densified intermetallics, smart composites, and hard coatings carried out by GFA researchers greatly contributed to the worldwide competition to harness the potential of SHS. On the occasion of the 40th anniversary of SHS, this paper is giving an overview of the main results obtained by GFA over the last ten years
