Corrosion of zirconium alloys is an electrochemically-driven process affected by the microstructure and microchemistry of the alloy surface, the nature of the oxide layer that forms, the temperature at the metal/oxide interface, the chemistry and thermohydraulics of the corroding water, the effects of irradiation and the effects of time.
Zirconium is also used as an alloying agent in steel, to make some types of surgical equipment and as a getter, a material that combines with and removes trace gases form vacuum tubes. Zirconium metal is weldable and formable. Zirconium 702 offers excellent corrosion protection with resistance to stress-corrosion cracking and crevice corrosion.
Stainless steel – zirconium alloys were developed by the US Department of Energy Laboratories as metallic waste forms for noble metal fission products. This thesis evaluates iron–zirconium–rhenium alloys to establish a technical basis for using metal waste form alloys for technetium-99 immobilization. Rhenium is used as a surrogate for Tc ...
by testing in air, of the zirconium-modified alloy to those of a Ni-30Cu alloy reveals that the precipitation-strengthened alloy has improved tensile properties to 1200 K and im-proved stress-rupture properties to 1100 K. For example, at 1000 K the zirconium-modified alloy exhibited a 40 percent higher yield strength and a four times greater
The Ugine plant's main activities take place in different shops: The pre-material preparation shop sorts the scraps and the recycled materials used to produce ingots.The compaction shop assembles the various components of zirconium alloys into electrodes. These consist of chips of recycled materials, zirconium sponge and additives.
More modern alloys have the potential to withstand even more severe duty conditions. This chapter covers the development of Zr alloys and gives the technical background for their use in the last 50 years. Much literature exists about zirconium alloys and several useful reviews exist for more detailed study. [1-4] 17.2. Motivation for use of Zr ...
OAK RIDGE, Tenn., April 13, 2018 – A team led by researchers at the Department of Energy's Oak Ridge National Laboratory has developed a safer cladding for nuclear fuel rods. The new material, an alloy of iron, chromium and aluminum, avoids zirconium. As a result, it should give plant operators substantially more time to react to incidents such as a station blackout.
zirconium-containing Ti-alloys, such as those studied b y Kim et al., contained Nb, Ta, P d and In, in addition to TiZr (roughly 20% Zr) [18]. These experimental TiZrNbTaPd(In) alloys were found to
Cumulative zirconium and zirconium alloy creep data over a broad range of stresses (0.1 to 115 MPa) and temperatures (300 °C to 850 °C) were analyzed based on an extensive literature review and ...

zirconium in aluminum alloys. If the major alloying elements are assumed to leave unchanged the free energy of Al 3Zr (D0 23 or L1 2), it is possible to compute their effect on the metastable zirconium solubility limit (see Table 1). As can be seen, the more positive the solute-zirconium interaction, the lower the zirconium solubility limit.
Zirconium alloys are used in space vehicle parts for their resistance to heat, an important quality given the extreme heat associated with atmospheric reentry. Zirconium Compounds . As a transition metal, zirconium forms various inorganic compounds, such as zirconium dioxide (ZrO2).
Zirconium and its alloys are widely used as a cladding for nuclear reactor fuels. Zirconium alloyed with niobium or tin has excellent corrosion properties. The high corrosion resistance of zirconium alloys results from the natural formation of a dense stable oxide on the surface of the metal. This film is self healing, it continues to grow ...

Zirconium has many similarities with titanium, and in terms of coordination modes, the ligands employed for titanium can certainly coordinate zirconium metal centers in order to form the corresponding zirconium complexes. As expected, alcohols are also good candidates for zirconium ligands. 69 The previously described BINOL (8) and 6,6'-dibromo-BINOL (14) have been also examined as ligands for ...
Zirconium alloys poorly with most elements and is miscible only with titanium, hafnium, and scandium. Thus, most elements have very low solubility in zirconium and form intermetallic compounds as second phase precipitates. Iron is the major, most visible impurity in zirconium, and zirconium–iron compounds are the most important to consider.
