Khoom Description
Tungsten tooj liab alloy yog ib qho alloy uas muaj ob lub ntsiab lus hlau, tungsten thiab tooj liab. Cov ntsiab lus tooj liab ntawm cov alloys feem ntau yog nruab nrab ntawm 10% thiab 50%, thiab cov ntsiab lus tungsten yog sib npaug ntawm 90% thiab 50%. Kev hloov pauv ntawm qhov piv no tuaj yeem cuam tshuam rau tag nrho cov khoom ntawm cov alloy.
Ntawm qhov kub siab heev (xws li saum toj 3000 degree), tooj liab hauv cov hlau yuav liquefy thiab evaporate, nqus cua sov ntau thiab txo qhov kub ntawm cov khoom, yog li nws tseem hu ua hlau tawm hws cov khoom. Cov yam ntxwv no ua rau tungsten tooj liab alloy muaj qhov zoo heev ablation tsis kam ntawm qhov kub thiab txias arc ib puag ncig. Lub ntim expansion coefficient ntawm tungsten tooj liab alloy yog me me, uas txhais tau hais tias qhov luaj li cas ntawm cov alloy yog me me nyob rau hauv high kub los yog kub kub, yog li xyuas kom meej nws stability.
Vim hais tias tungsten thiab tooj liab muaj cov ntsiab lus melting siab thiab tsis sib haum nrog ib leeg, txoj kev casting tsoos tsis haum. Yog li ntawd, tungsten tooj liab alloy feem ntau yog tsim los ntawm hmoov metallurgy. Txoj kev no suav nrog pulverizing, sib tov cov khoom xyaw, nias, sintering, infiltration thiab ua haujlwm txias. Ntxiv nrog rau hmoov metallurgy, muaj ntau cov txheej txheem ntau lawm xws li infiltration, high-temperature kua theem sintering thiab activated kua theem sintering. Cov txheej txheem no muaj lawv qhov zoo thiab qhov tsis zoo, thiab tsim nyog rau kev tsim khoom sib txawv thiab kev ua haujlwm ntawm alloy.
Nyob rau hauv ib lo lus, tungsten tooj liab alloy plays lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub nrog nws cov khoom siv lub cev thiab tshuaj lom neeg thiab kev siv dav dav. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho thev naus laus zis, cov khoom ntawm tungsten tooj liab alloy yuav raug txhim kho ntxiv, thiab nws daim ntawv thov teb yuav dav dua.
