Alloyed/modified

Cupro-Nickels. At the present time, most marine operators agree that the cupro-nickels are the most useful material of construction for sea-water plants. Since World War II, the 90 Cu-10 Ni alloy modified with about 1.5% of iron has become well established. The lower nickel content results in a cost advantage over the 70 Cu-30 Ni alloy. Alloys containing 70 Cu-30 Ni or 80 Cu-20 Ni, each with added iron, are preferred by some designers to withstand more severe conditions.

A 7xxx series alloy modified with Sc has been developed with potential to replace the titanium alloy used for a cryogenic fuel pump component application. 

The objectives of this Workshop, to present and discuss new results in the development and processing of metallic materials with high structural efficiency and to establish new interactions and networks between the participants, were successfully met. A number of new developments were presented and discussed at this Workshop, including recent information on titanium alloys modified with relatively small amounts of B and Si to provide dramatic improvements in strength and stiffness, and new A1 alloys strengthened with quasicrystalline precipitates for good elevated temperature properties. In addition, a current extensive update on severe plastic deformation and on nanocrystalline metals for structural applications was provided.

Reformer tubes typically operate at maximum temperatures of 1600 to 1700°F and are designed for a minimum stress-to-rupture life of 100,000 operating hours. Today s preferred metallurgy is a 35/25 Ni/Cr alloy modified with niobium and microalloyed with trace elements including titanium and zirconium. 

Finally, as can be seen from the consideration above, new findings in developments of Ni-Mo alloys for MSR with fuel salt temperatures up to 750°C shift the emphasis from alloys modified with titanium and rare earths to those modified with niobium in ORNL [49] and aluminum in NRC-KI [15].

The development of microstructure in both single- and two-phase alloys typically involves some type of phase transformation—an alteration in the number and/or character of the phases. The first portion of this chapter is devoted to a brief discussion of some of the basic principles relating to transformations involving solid phases. Because most phase transformations do not occur instantaneously, consideration is given to the dependence of reaction progress on time, or the transformation rate. This is followed by a discussion of the development of two-phase microstructures for iron-carbon alloys. Modified phase diagrams are introduced that permit determination of the microstructure that results from a specific heat treatment. Finally, other microconstituents in addition to pearlite are presented and, for each, the mechanical properties are discussed. 

With a dopant, the respective size of the different zones in the //-crystallized alloys changes as well as the distribution of the dopant. It is not the case for Cu, so the difference in selectivity between the samples Issued from the as-cast and the //-crystallized alloys was in the same order as the one obtained with the undoped catalysts. In the case of Cr-doped //-alloys, chromium was segregated in the interdendritio zone and no Cr-rich phases such as Alg(CrNi)s were observed as in the as-cast alloy. The //-crystallization of Cr-doped alloy modified both the A1 and the Cr distribution. Therefore, it is not surprising that not only the activity, but also the selectivity were modified.

The formation of Ni(OH)2 at the electrode leaves behind a Cu-enriched surface which can be also oxidized to CU2O and finally to Cu(OH)2. At the end, the surface film will be a mixture of NiOOH and Cu(OH)2 where the counterions are mobile enough to maintain electroneutrality at the electrode surface during the redox process. When a NiCu alloy-modified electrode comes in contact with organic pollutants present in the sample the Ni(lll) species rapidly oxidize them and form Ni(ll) species, as follows ...
