Hlau paub txog Tungsten Rhenium Alloys
Rhenium yog kim, nyob rau hauv daim ntawv thov ntawm rhenium muaj alloys, ntawm uas tungsten rhenium thiab molybdenum rhenium alloys yog cov feem ntau lug siv. Tungsten-rhenium alloys muaj 10 feem pua -26 feem pua rhenium, thiab molybdenum-rhenium alloys muaj 11 feem pua -50 feem pua rhenium. Tsis tas li ntawd, muaj W-33.3Mo-33.3Re, Mo-Re-Hf-Zr, Mo-Re-Hf-V alloys, tom kawg ob alloys muaj zog dua.
Tungsten rhenium thiab molybdenum rhenium alloys muaj qhov kub thiab txias zoo, tuaj yeem ua tiav rau hauv daim hlau, nplooj ntawv, xov hlau, xov hlau, pas nrig, qhov kub thiab txias ntawm cov khoom siv rau aerospace, cov khoom siv elastic, cov khoom siv hluav taws xob, thiab lwm yam. tsim cov khoom cua sov, workpieces, qij, X-ray seev thiab cov khoom siv kho mob.
Cov khoom tseem ceeb ntawm molybdenum rhenium alloy yog Mo41Re, Mo44.5Re thiab Mo47.5Re. Hmoov metallurgy txoj kev yog txoj hauv kev zoo tshaj plaws los npaj molybdenum rhenium alloy ingot, thawj molybdenum hmoov thiab rhenium hmoov sib tov sib xyaw, thiab tom qab ntawd nias los yog isostatic siab, thiab tom qab ntawd los ntawm kev kub kub sintering tuaj yeem tsim cov txheeb ze ntom ntom ntawm li 90 feem pua molybdenum rhenium alloy.
Tungsten-rhenium alloy muaj cov khoom zoo heev, xws li cov ntsiab lus siab melting, siab zog, siab hardness, siab plasticity, siab recrystallization kub, siab resistivity, tsis tshua muaj vapor siab, tsis tshua muaj electron khiav hauj lwm thiab tsis tshua muaj yas brittle hloov kub. Tungsten-rhenium alloys feem ntau ua rau hauv tungsten-rhenium xov hlau thiab cov khoom siv thermocouple.
Vim hais tias ib zaug cov tungsten hlau yog recrystallized tom qab siv kub, nws yuav nkig heev thiab yog yooj yim tawg nyob rau hauv kev cuam tshuam los yog kev co. Hauv qee cov khoom siv hluav taws xob hluav taws xob uas xav tau kev ntseeg siab, txhawm rau tiv thaiv kev tawg ntawm cov filament, 3-5 feem pua rhenium feem ntau ntxiv rau doped tungsten hlau los ua rhenium tungsten hlau, uas tuaj yeem ua rau tungsten brittleness hloov. kub poob rau hauv chav tsev kub los yog hauv qab no. Tsawg rhenium alloy thiab siab rhenium alloy hlau tuaj yeem sib xyaw rau hauv cov thermocouples, uas muaj qhov zoo ntawm cov khoom siv hluav taws xob muaj peev xwm, txhim khu kev qha thermal stability thiab pheej yig tus nqi. Tungsten-rhenium thermocouples nrog cov cuab yeej tso saib tuaj yeem ntsuas qhov ntsuas kub ntawm cov kua, chav thiab roj. Nws tuaj yeem hloov pauv cov platinum rhodium thermocouple ua cov cuab yeej ntsuas kub rau kev lag luam high-tech metallurgical, kub kub hluav taws xob hluav taws xob hluav taws xob cov qauv engineering thiab chaw tsheb, thiab nuclear reactors.
