Taw qhia rau Molybdenum Alloys

Molybdenum alloys tsis yog -ferrous alloys uas muaj molybdenum raws li ib tug matrix, nrog rau ntxiv ntawm titanium, zirconium, hafnium, tungsten, rhenium, thiab tsis tshua muaj ntiaj teb cov ntsiab lus. Lawv muaj cov ntsiab lus melting siab, kub tsis kam, corrosion kuj, thiab zoo heev - kub lub zog (1100-1650℃). Lawv cov khoom yog txhim kho los ntawm kev daws teeb meem ntxiv dag zog, nag lossis daus ntxiv, thiab carbide dispersion ntxiv dag zog rau cov txheej txheem. Lawv tsuas yog siv rau hauv cov khoom siv hauv aerospace, cov khoom siv hluav taws xob nuclear, cov raj hluav taws xob, thiab kev tsim khoom siv tub rog.

Cov khoom no yog thawj zaug uas siv cov hmoov metallurgy hauv xyoo 1910, thiab nws txoj kev loj hlob tau txuas ntxiv los ntawm kev siv tshuab arc melting tom qab xyoo 1945. Nyob rau xyoo 1950, Mo-0.5Ti-}0.02C thiab TZM alloys tau tsim, thiab hauv xyoo 1970, Mo{C.{12} alloys tau tsim. Tuam Tshoj tau tsim cov khoom lag luam molybdenum nyob rau xyoo 1950s, maj mam ua tiav cov khoom lag luam ntawm cov kav dej, phaj, thiab lwm yam ntaub ntawv. Txij li thaum pib ntawm lub xyoo pua 21st, kev ua txhaum ntawm kev tswj cov thev naus laus zis tau ua tiav hauv nanostructured dispersion-strengthened molybdenum alloys, thiab tsis tshua muaj lub ntiaj teb doping tau txhim kho kev tiv thaiv siab kub deformation. Alloys xws li TZM thiab ZHM tau siv rau ntawm qhov loj hauv cov teb xws li foob pob hluav taws cav nozzles thiab photovoltaic cell backsheets.
