“…Impact tests performed on these samples revealed the embrittlement of the welds by the Zr 2 (Fe,Ni) coumpound. In all the cases presented above, the nucleation of brittle phases (either Laves-type or intermetallics) has the strongest impact on the joints mechanical properties and corrosion resistance [14]. Improving these properties requires decreasing the occurence of these compounds at the Zy 4 -SS 304L interface, as well as the decrease of the diffusion zone thickness.…”

“…The studies on direct diffusion bonding between Zircaloy 4 and steel AISI 304L can lead to variable reaction layer thicknesses [9,10,11,12] and to reaction layers containing several microstructurally different areas [13,14], depending on the processing parameters. The complex microstructure observed in diffusion bonded Zircaloy 4 (Zy 4 ) -stainless steel AISI 304L (SS 304L) joints is again inherited from the coexistence of numerous phases, from solid solutions to intermetallics and Laves phases.…”

“…The Laves phases in particular are expected to be the main source of crack initiation during mechanical testings due to their very high hardness. Although many studies have been undertaken, identification and kinetics formation of some phases remain controversial [11,14]. A recent study performed on the diffusion bonding at 1323K for 45 minutes holding time, indicates a ∼700µm thick reaction layer containing many phases and revealing the presence of a transient liquid phase [15].…”

“…Diffusion bonding of stainless steels to Zr-4 has been widely studied [25][26][27]. In 1978, Shaaban et al [25] investigated Zr-4 diffusion bonding with 304 stainless steel.…”

“…The resulting microstructure, however, was rich in hard ZrCr 2 intermetallics, leading to a brittle diffusion bond. More recently, Taouinet et al [27] characterized the solid state diffusion interface between Zr-4 and 304L stainless steel, showing the formation of 3 distinct layers: A zone of a-FeCr solid solution, an area rich in the intermetallic compound Zr(Fe,Cr) 2 , and a third zone, composed of a-Zr and the intermetallic Zr 2 (Fe 1Àx Ni x ). The Cr-rich layer, adjacent to the steel side, acted as a diffusion barrier.…”

h i g h l i g h t sThe diffusion bonding of Ti 3 SiC 2 and Ti 2 AlC to Zircaloy-4 cladding was investigated. Si penetration into the Zr-4 was roughly an order of magnitude less than that of Al. The resultant bonds using Ti 2 AlC were weak and full of cracks. The Ti 3 SiC 2 /Zr-4 bonds were stronger, and withstood the forces of sectioning. a b s t r a c tHerein, we report on the interactions between zirconium, in the form of Zircaloy-4 (Zr-4) and the MAX phases, Ti 3 SiC 2 and Ti 2 AlC in the 1100-1300°C range. In both cases, the A-group element, Al or Si, diffused out of the MAX phases and formed intermetallics with the Zr-4. Under comparable conditions, Si penetration into the Zr-4 was roughly an order of magnitude less than that of the Al from the Ti 2 AlC. The effective diffusion coefficient of Si can be described by D eff Si m 2 s ¼ 7:4 Â 10 À9 exp À170 kJ=mol RT ð Þ ; that of Al by D eff Al m 2 s ¼ 9:3 Â 10 À12 exp À38 kJ=mol RT ð Þ . At 38 kJ/mol, the activation energy for the Ti 2 AlC/Zr-4 diffusion bonding process was significantly lower than that of the Ti 3 SiC 2 /Zr-4 diffusion couples, at 170 kJ/mol.

Diffusion bonding of stainless steel 304 L and zircaloy‐4 (Zr‐4) in solid state is conducted using Ni and Ta as the hybrid interlayer at the bonding temperature of 850−1000 °C for the bonding time of 30 min under the bonding pressure of 6 MPa in vacuum. The effect of the bonding temperature on the microstructure and the mechanical properties of the joints is investigated. The microstructure analysis is conducted by a scanning electron microscope, energy dispersive spectroscopy, and X‐ray diffraction. The mechanical properties of the joints are measured by a shear test and microhardness test. The results show that Ni3Ta intermetallic compounds are formed at the Ni/Ta interface, and the solid solution of Zr and Ta appears at the Ta/Zr‐4 interface. In the meantime, the maximum shear strength reaches 194 MPa and the highest hardness value across the interface of joints is 356 HV in the Ni3Ta layer.
