Tungsten Rhenium Alloy AMERICAN ELEMENTS

In its elemental form, rhenium has a silvery-white appearance. Rhenium is the fourth densest element exceeded only by platinum, iridium, and osmium. Rhenium's high melting point is exceeded only by those of tungsten and carbon. Rhenium is found in small amounts in gadolinite and molybdenite.

Tungsten Rhenium Wire Properties and Uses Union City

About 3% Rhenium/97% Tungsten Wire The development of 3% rhenium/97% tungsten wire is a result of a continuous research effort that has been conducted since the early 1900’s. One of the first accomplishments of this research was a non-sag grade of tungsten wire, which used grain growth controlling additives to modify the recrystallized structure.

YIELDING AND FRACTURE IN TUNGSTEN AND TUNGSTEN

A study was made of the mechanical properties of vacuum arc-melted tungsten and tungsten-rhenium alloys in the temperature range 77' to 810' K in order to elucidate the mechanism by which rhenium additions lower the ductile-brittle transition temperature of tungsten. The temperature and s t ra in-rate dependency of the yield s t r e s s of tungsten is reduced by alloying with rhenium.

It's Elemental The Element Tungsten

Tungsten was discovered by Juan José and Fausto Elhuyar, Spanish chemists and brothers, in 1783 in samples of the mineral wolframite ((Fe, Mn)WO 4).Today, tungsten is primarily obtained from wolframite and scheelite (CaWO 4) using the same basic method developed by José and Elhuyar.Tungsten ores are crushed, cleaned and treated with alkalis to form tungsten trioxide (WO 3).
