| titleOfInvention | A kind of potassium zirconium carbide codope tungsten alloy and preparation method thereof |
| abstract | The invention discloses a kind of potassium zirconium carbide codope tungsten alloys and preparation method thereof, tungsten alloy is made of K, Al, Si, ZrC and W, by weight percentage, K content is 0.003 ~ 0.03%, ZrC content is 0.1 ~ 1.5%, the total content of Al, Si alloying element is less than or equal to 0.05%, and W content is 98.4 ~ 99.85%, remaining is impurity.Tungsten alloy of the invention has excellent low-temperature flexibility, elevated temperature strength and high-temperature stability, has obvious plasticity at 150 DEG C；Intensity is much higher than potassium Doped Tungsten and pure tungsten, also significantly greater than tungsten-carbonization zircaloy；After 1600 DEG C are annealed 1 hour, tungsten alloy of the invention improves 40% or more than potassium Doped Tungsten and tungsten-the carbonization zircaloy of the same terms in 500 DEG C of intensity.Plasma resistant etching performance of the invention is close with tungsten-carbonization zircaloy, but is better than potassium Doped Tungsten and pure tungsten. |
