“…5). This behavior has been mentioned by many authors [11,12,20] indicating the formation of a Cr-rich border at the Zircaloy=Stainless Steel interface, which constitutes a diffusion barrier of Zr from Zircalo-4 toward the stainless steel. Beyond this region (Zone I), in Zone II, the Cr concentration decreases rapidly for the benefit of Zr reaching a value of 38 at%.…”

“…We must specify here that in previous work on the diffusion bonding between the stainless steel and Zircaloy, some authors show that the interdiffusion of chemical elements between the two entities form an interface consisting only of two distinct areas [12,13]. Some authors also report that the interface between the Zircaloy-4 and 316L stainless steel is composed of two zones [16].…”

“…However, other authors found a ternary compound, containing Zr, Fe, and Ni [12,13]. Mazar Atabaki and Talebi Hanzaei report the presence of intermetallics, similar to Zr(Cr, Fe) [16] who worked on the couple Zircaloy-4=316L, welded at 1,000 and 1,050 C, where the Ti is also used as an intermediate, deposited by thermal evaporation between the alloys, indicate the formation at the interface of a eutectic Zr 2 Fe Zr 2 Ni and Zr(Cr, Fe) 2 þ Zr 2 Fe and also the intermetallics of the type Zr(Cr, Fe) 2 , Zr 3 Fe.…”

“…The bonds between stainless steels and the Zircaloy, obtained by diffusion bonding in the solid state, with or without filler metals, have been the subject of various scientific works [10][11][12][13]. The studies related to the elements diffusion of the welded compounds across the obtained interface, and also, to the nature of the formed phases, between stainless steel and Zircaloy bonded by diffusion without filler metal, are not very available in the literature.…”

“…[12], reports the presence of binary intermetallic compounds of the type ZrCr 2 , and Zr 2 Fe Zr 2 Ni with the formation of a Cr-rich zone on the stainless steel side at the interface Zircaloy-2=stainless steel. Both phases Zr 2 Ni and Cra are not cited in the survey of Shaaban and Hammad [13] on the diffusion bonding.…”

Diffusion bonding in the solid state between the zirconium alloy (Zircaloy-4) and AISI 304L stainless steel (304L SS) was studied at a temperature of 1,050 C under a dynamic pressure in a controlled atmosphere. We discussed the morphology of the interface formed by determining the distribution of the various chemical constituents as well as the location and the identification of the different phases nature formed through due to chemical exchange reactions that occurred by diffusion through the interface. Observations and chemical analysis were performed by environmental scanning electron microscope (ESEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). The junction is composed of three distinct zones formed of a solid solution (FeCr)a rich in Cr as a homogeneous edging from steel side. The type phase Zr(Fe,Cr) 2 occupies the Zone II and phase Zr 2 (Fe,Ni) Zone III between them settled the eutectic Zr a -Zr(Fe,Cr) 2 . . The observations and analysis of the fracture surfaces obtained by impact testing showed a morphology of a brittle fracture by cleavage which is located at the interface. The microhardness filiation at the interface of both materials diffusion bonded is very heterogeneous.
