“Mechanical tests showed that the composite was significantly more ductile than pure tungsten. It could withstand deformation ...

IT has been known for a long time that perfectly pure tungsten cannot be used for the manufacture of filaments for electric lamps on account of its “off-setting” structure due to ...

“Bamboo” Structure. Recrystallized pure tungsten wire develops a bamboo structure: the grains inhabit the whole wire diameter, and the boundaries are basically perpendicular to the wire axis. At very ...

Pure tungsten is a silver-white metal and when made into a fine powder can be combustible and can spontaneously ignite. Natural tungsten contains five stable isotopes and 21 other unstable isotopes.

In the sense of animal, vegetable, or mineral, the USGS lists 35 minerals that are essential to the function of our society. Whether it’s indium for LCD screens, Co for iPhones, U for reactors ...

The macroscopic polarization of these ceramics was temperature-insensitive, including the polarization distribution state and domain size variation. X-ray Rietveld refinement indicated the presence of ...

When welding thin aluminum (0.09 in. or less) thoriated tungsten is also a good alternative to pure tungsten because it creates a more focused arc.
