The alloy element Rhenium transfers a number of interesting characteristics to Tungsten. Due to this fact the recrystallization temperature and electrical resistance is higher. In addition to that a major advantage is the higher ductility, especially after heating respectively recrystallization.

Tungsten-rhenium alloy rods are cut into discs and used as electrical contact materials. They have low contact resistance, low arcing current and arcing voltage, optimal arc stabilization performance, and low arc erosion resistance. Therefore, they are widely used to replace platinum contact materials. 3.

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. The tungsten-rhenium […]

01-08-2020· 01-08-2020· When alloyed with rhenium, tungsten exhibits a pronounced increase of ductility which is of fundamental importance for many applications. ... (d c /b) reflects the dependence of the line tension T on the outer cut-of radius taken equal to d c, and the proportionality term is deduced from anisotropic elasticity calculations .

It has been reported that the optimum concentration of rhenium in tungsten is about 4 at.% or greater than 20 at.% to provide optimum ductilizing effect. In order to improve high-temperature strength, second-phase strengthening has also been utilized in the development of tungsten-base alloys. Among various potential second-phase particles ...

01-06-2016· The pure tungsten rod was 20 mm in diameter and 30 mm long, and the tungsten rhenium rods were 15 mm in diameter and 100 mm long. Discs of approximately 1 mm thickness were cut from the rods, using Electrical Discharge Machining (EDM) and then polished to a mirror finish and cleaned ultrasonically using ethanol and acetone.
