Rhenium alloys were investigated as substrates for diamond film growth. Mechanical bend testing and imaging compared alloy ductility and microstructure. Molybdenum-rhenium alloys stayed more flexible than tungsten and tungsten-rhenium. Embrittlement was limited to the outer shell of the molybdenum-rhenium wires

Some commercial type Fischer–Tropsch catalysts are based on rhenium-doped cobalt. In an attempt to elucidate the preferred position of rhenium in the cobalt matrix, we have carried out experimental Low Energy Ion Scattering investigations of oxidized and reduced catalyst samples and computational DFT investigations of bimetallic Co/Re clusters. The results indicate that rhenium ...

Mo- or W-rhenium alloys The effect of large additions of rhenium to molybdenum and to tungsten is quite remarkable. In these two systems the influence of rhenium is similar, though it is more marked with molybdenum and here attention will be concentrated on the Mo - Re system (Fig. 20). The initial discovery of the ductility of the 35 at.
Tungsten powder is the main raw material for processing tungsten alloy. Pure tungsten powder can be made into wire, rod, tube, plate and other processing materials and certain shape products. Tungsten powder mixed with other metal powder, can be made into all kinds of tungsten carbide, such as tungsten cobalt alloy, tungsten rhenium alloy ...

During engineering-scale (ES) tests of BV, a small fraction of radioactive technetium-99 (Tc) (and rhenium [Re], a nonradioactive surrogate) were transferred out of the LAW glassmore » Tc is a primary risk driver for long-term performance of immobilized LAW; therefore, even small fractions of Tc present in a readily leachable form rather than ...
After modification, the cracks of the rhenium coating were sealed by rhenium-cobalt alloys and the ductility and mechanical strength of the coating had a remarkable improvement.
Rhenium nanowires have been fabricated via directional solidification and selective etching of a eutectic alloy. A NiAl–1.5 at.%Re eutectic alloy was directionally solidified using a constant ...

China Molybdenum Co will take direct control of metals trader IXM in a $495-million buyout of a fund it set up to originally purchase the firm from Louis Dreyfus, according to a notice issued on the Hong Kong Stock Exchange on Tuesday December 4.
Molybdenum-rhenium (Mo/Re) and tungsten-rhenium (W/Re) alloys were investigated as substrates for thin-film, polycrystalline boron-doped diamond electrodes. Traditional, carbide-forming metal substrates adhere strongly to diamond but lose their ductility during exposure to the high-temperature (1000°C) diamond, chemical vapor deposition ...

Rhenium is added to nickel-based super alloys to improve creep strength of the alloys. Rhenium filaments exhibit a higher stability, and hence they can be used in photoflash lamps, ion gauges and mass spectrometers. Rhenium radioactive isotopes are used for treating liver and pancreatic cancer where it is delivered through a bacterial host.
