used to manufacture molybdenum-alloy steel. During melting, the gangue ends up in the slag. However, tech oxide must be puriﬁed chemically to use it in the manufacture of molybdenum metal. Figure 1 is a ﬂow chart of molybdenum metal manufacturing, starting with tech oxide. The oxide is ﬁrst dissolved in ammonium or sodium hydroxide, and this
Alloys of molybdenum and rhenium are more ductile than pure molybdenum. An alloy with 35% Re can be rolled at room temperature to more than 95% reduction in thickness before cracking. For economic reasons, molybdenum-rhenium alloys are not widely used commercially. Alloys of molybdenum with 5 and 41% Re are used for thermocouple wires.

Molybdenum-Rhenium, commonly known as Moly-Rhenium (Mo-Re), is used extensively in industries as diverse as medicine, defense, pure research and production welding. Thanks to its excellent thermal and mechanical properties, this material is a less costly alternative to pure rhenium.
Molybdenum based alloys are widely used, because they are cheaper than superior tungsten alloys. The most widely used alloy of molybdenum is the Titanium-Zirconium-Molybdenum alloy TZM, composed of 0.5% titanium and 0.08% of zirconium (with molybdenum being the rest). The alloy exhibits a higher creep resistance and strength at high temperatures, making service temperatures of …

Rhenium (Re), the last naturally-occurring element to be discovered, was discovered in Germany in 1925. The process was so complicated and the cost so high that production was discontinued until early 1950 when tungsten-rhenium and molybdenum-rhenium alloys were prepared.
A molybdenum-rhenium alloy having an excellent low temperature ductility paired with an excellent high temperature strength. The alloy consists, essentially in % by weight, of 42 up to <45% Re, up to 3% each of W, Y, Rh, Sc, Si, Ta, Tb, V, Nb or Zr at which the sum of said elements is no greater than about 5%, the remainder being Mo besides normally present impurities.
Rhenium and rhenium containing alloys are unique metals with high melting points, high moduli of elasticity and high temperature mechanical properties. The most common rhenium containing alloys are molybdenum-41wt% rhenium (Mo41%Re) and molybdenum-47.5wt% rhenium (Mo47.5%Re).

1.1 This specification covers the chemical, mechanical, and metallurgical requirements for wrought molybdenum-47.5 rhenium alloy to be used in the manufacture of surgical implants. 1.2 The SI units in this standard are the primary units. The values stated in either primary SI units or secondary inch-pound units are to be regarded separately as ...
It has frequently occurred that basic work on an alloy system has been undertaken with one particular technology in mind but that progress has eventually taken place on an entirely different front. Such appears again to be the case with the ruthenium-molybdenum and …
The addition of rhenium to molybdenum improves plasticity and weldability and decreases brittleness for certain temperature ranges. It is used throughout the aerospace and electronics industries for applications such as nuclear reactors, semiconductors, electrical contacts, filaments and igniter wires.
Rhenium Alloys. In addition to pure rhenium H. Cross Company also produces a 50/50 (48% rhenium by analysis) rhenium molybdenum alloy that combines the strength of molybdenum and rhenium's ductility. This product is available in all the same forms and sizes as pure rhenium at lower cost due to the lower rhenium percentage.

Various Mo-Re alloys are attractive candidates for use as fuel cladding and core structural materials in spacecraft reactor applications. Molybdenum alloys with rhenium contents of 41% to 47.5% (wt%), in particular, have good creep resistance and ductility in both base metal and weldments.
Other Molybdenum Metal Alloys Include: TZM Molybdenum – 99% MO, 0.5% Ti, and .0.08 ZR Molybdenum / 50% Rhenium Molybdenum / 30% Tungsten Molybdenum / Copper
Rhenium is quite a rare metal: its concentration is about 0.7 ppm in the earth's crust. It is the last naturally occuring element to be discovered (1925). Most rhenium today is produced as a by-product of the copper mining industry: rhenium is found in those copper ores contaminated with molybdenum.
Molybdenum-98 is the most abundant isotope, comprising 24.14% of all molybdenum. Molybdenum-100 has a half-life of about 10 19 y and undergoes double beta decay into ruthenium-100. Molybdenum isotopes with mass numbers from 111 to 117 all have half-lives of approximately 150 ns.
