Study of secondary intermetallic phase precipitation/dissolution in Zr alloys by high temperature–high sensitivity calorimetry

Circumferential creep properties of stress-relieved Zircaloy-4 and Zr–Nb–Sn–Fe cladding tubes

“…Based on the EDS analysis, the b-Nb precipitates as well as the precipitates containing Fe alloying element were observed in Zr-Nb-Sn-Fe. This confirms the observation that b-Nb and ZrNbFe precipitates exist in the commercial grade of Zr-Nb-Sn-Fe alloy [37,38].…”

Modelling precipitation in zirconium niobium alloys

“…Niobium containing SPPs form in these alloys, playing a key role in controlling corrosion resistance, hydriding properties, and grain size evolution (e.g. [5][6][7][8]). …”

Changes in phase composition of Zr–Fe–V getter after hydriding and vacuum dehydriding cycles

“…The precious study [18] explored the dissolution of Zr-Fe-based alloys during heating, precipitation of secondary intermetallic phases during the cooling, and a major influence of these phases on the material corrosion and mechanical behavior. The reversibility of this reaction was discussed in dependence on the rate of thermal diffusivity of the alloying elements (Cr, V, Nb, and Mo).…”
