“…Secondly, metallurgical incompatibilities of them are prone to form brittle intermetallic compounds at a welding pool. For example, according to the TiFe binary phase diagram, the solid solubility of Fe in Ti is less than 0.1 at.%, and thus TiFe and TiFe 2 phases are formed at the bonded joints where cracks are liable to emerge and propagate spontaneously [6,[11][12][13][14][15].…”

High-quality joints between titanium alloys and stainless steels have found applications for nuclear, petrochemical, cryogenic, and aerospace industries due to their relatively low cost, lightweight, high corrosion resistance, and appreciable mechanical properties.is article reviews diffusion bonding between titanium alloys and stainless steels with or without interlayers. For diffusion bonding of a titanium alloy and a stainless steel without an interlayer, the optimized temperature is in the range of 800-950°C for a period of 60-120 min. Sound joint can be obtained, but brittle FeTi and Fe-Cr-Ti phases are formed at the interface. e development process of a joint mainly includes three steps: matching surface closure, growth of brittle intermetallic compounds, and formation of the Kirkendall voids. Growth kinetics of interfacial phases needs further clarification in terms of growth velocity of the reacting layer, moving speed of the phase interface, and the order for a new phase appears. e influence of Cu, Ni (or nickel alloy), and Ag interlayers on the microstructures and mechanical properties of the joints is systematically summarized. e content of FeTi and Fe-Cr-Ti phases at the interface can be declined significantly by the addition of an interlayer. Application of multi-interlayer well prevents the formation of intermetallic phases by forming solid solution at the interface, and parameters can be predicted by using a parabolic diffusion law. e selection of multi-interlayer was done based on two principles: no formation of brittle intermetallic phases and transitional physical properties between titanium alloy and stainless steel.

“…Intermetallic compounds (IMC), metal and ceramic matrix composites, nanostructured materials, amorphous materials, highly refractory metals and ceramics can all be processed using SPS (see Table 1). This process provides several advantages including sintering of materials like tungsten carbide [183], high sintering speed, low power consumption, reasonable performance, safety and reliability [65,139,158].…”

“…Furthermore have SPS been used for Ti to Steel joining, without the brittle Fe-Ti intermetallic compounds (IMC) and shape distortion of parent materials [157]. A joint of Ti6Al-4V to low alloy steel made at 950 8C was reported to have a maximum tensile strength of 250 MPa [158].…”

“…Diffusion bonding of SiC parts requires simultaneous application of high temperature (higher than 2000 C) and pressure and is usually conducted using hot pressing equipment. Recently, spark plasma sintering (SPS) apparatus was successfully used for joining of similar and dissimilar ceramics, as well as ceramics to metals specimens [14][15][16][17]. Optimal joining parameters provide a homogeneous structure of bonded regions and adequate mechanical properties of the joints.…”

This work reports results of silicon carbide plates, disks, pipes, and pipe-disk couples bonded by a spark plasma sintering apparatus. The joining was conducted at 1900 C for 30 min with a 35 MPa uniaxial pressure. The samples were analyzed by Scanning acoustic microscopy, which in turn revealed a low amount of small defects at the samples' periphery. Scanning acoustic microscopy results were verified through scanning electron microscopy and nanoindentation. It was concluded that Spark Plasma Sintering technique may serve as a valid and effective tool for diffusion bonding of high-temperature-resistant silicon carbide with different geometries.
