Rhenium-tungsten hmoov (tungsten-rhenium alloy hmoov)
Rhenium-doped tungsten hmoov yog ib qho alloy nrog tungsten ua matrix thiab cov ntsiab lus sib txawv ntawm rhenium ntxiv. Tungsten thiab rhenium yog cov hlau refractory. Yog tias rhenium yaj hauv tungsten ntau txaus, nws tuaj yeem tsim cov khoom sib xyaw ua ke. Nyob rau hauv "rhenium effect", cov tungsten-rhenium alloy muaj plasticity siab dua, recrystallization kub siab dua, creep tsis kam zoo dua ntawm qhov kub siab, thermoelectric muaj peev xwm siab dua thiab resistivity siab dua li tungsten ntshiab. Cov tungsten-rhenium alloy muaj cov khoom siv hluav taws xob zoo, ductility thiab machability, thiab tuaj yeem siv rau thermocouple kub siab thiab cathode hlau. Tungsten-rhenium alloys muaj cov khoom siv kho tshuab zoo dua ntawm qhov kub siab dua li tungsten ntshiab thiab tuaj yeem machinedand thiab welded.
Rhenium muaj cov yam ntxwv hauv qab no: qhov chaw yaj siab, muaj zog tiv taus tshuaj lom neeg corrosion, ductility tom qab recrystallization, siab resistivity hla ntau qhov kub thiab txias, qis vapor siab, zoo oxidation tsis kam ntawm qhov kub thiab txias, thiab zoo shock tsis kam. Thaum ntau dua 0.1% rhenium ntxiv rau tungsten, cov khoom siv txhim kho pib pom tseeb, thiab nrog kev nce ntawm rhenium cov ntsiab lus, cov nyhuv kuj maj mam txhim kho.
Rheniumet series ntawm rhenium doped tungsten hmoov series mob siab rau kev tsim cov khoom siv tungsten zoo tshaj plaws, zoo, kev ua haujlwm siab lossis kev ua tiav deformation ntawm cov khoom tsim, xws li phaj, ntawv, hlau, hlau, pas nrig, tuaj yeem hloov cov tungsten ntshiab, lanthanum, cerium tungsten thiab tungsten doping tungsten thiab tungsten cov ntaub ntawv, dua li cov tungsten ntshiab muaj lub zog siab dua, kev pabcuam lub neej thiab kev ua haujlwm ruaj khov kub, cov yam ntxwv ntawm kev ua tau zoo dua rau tus nqi piv. Lawv feem ntau siv rau hauv cov khoom siv kub siab (nozzle, nozzle, tiv thaiv cua sov, thiab lwm yam), filament tshwj xeeb, electrode, cov khoom siv hluav taws xob, thiab lwm yam.
