Cov khoom siv ntawm tungsten tooj liab alloys

tungsten- tooj liab alloys yog cov alloys uas muaj tungsten thiab tooj liab. Cov alloys feem ntau muaj 10% -50% tooj liab. Cov alloys no yog tsim los ntawm cov hmoov hlau metallurgy thiab muaj cov khoom siv hluav taws xob zoo thiab thermal conductivity, zoo siab - qhov kub thiab txias, thiab ib qib ntawm plasticity. Thaum kub heev, xws li saum toj no 3000 degree, tooj liab nyob rau hauv lub alloy liquefies thiab evaporates, absorbing ib tug loj npaum li cas ntawm tshav kub thiab txo cov khoom ntawm qhov kub thiab txias. Yog li ntawd, cov ntaub ntawv no tseem hu ua "sweating metals."

tungsten- tooj liab alloys ua ke cov txiaj ntsig zoo ntawm ob qho tib si tooj liab thiab tungsten, nthuav tawm lub zog siab, siab lub ntiajteb txawj nqus, kub tsis kam, arc yaig tsis kam, zoo hluav taws xob thiab thermal conductivity, thiab zoo machinability. Siv high- zoo tungsten hmoov thiab oxygen- dawb tooj liab hmoov, thiab siv isostatic nias (siab-kub sintering- tooj liab infiltration), purity thiab raug proportions ntawm cov khoom yog guaranteed, ua rau ib tug zoo microstructure thiab ua tau zoo heev. Nws nthuav tawm qhov zoo arc- tawg kev ua tau zoo, hluav taws xob zoo thiab thermal conductivity, thiab qis thermal expansion.
