Density of Tungsten-Rhenium Alloy. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume.It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance.

In addition, it is worth noting that the formation energies of the tungsten-rhenium alloys are positive, which means that the tungsten-rhenium alloys is an endothermic reaction during the synthesis process. At the same time, it is found that as the concentration of rhenium increases, alloy synthesis will become more difficult.

Rhenium improves the properties of tungsten. Tungsten-rhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The high-temperature stability is also improved. The effect increases with the rhenium concentration, and therefore tungsten alloys are produced with up to 27% of Re, which is the solubility limit.

Application of Tungsten Rhenium Alloy. Tungsten and rhenium are both metals with a high melting point, and they are widely used in high-temperature fields. However, they also have shortcomings. For example, pure tungsten is brittle and has a low recrystallization temperature and pure rhenium has poor processing performance and is expensive, which greatly limits their application range.
