Molybdenum feem ntau siv dav hauv kev lag luam kev lag luam. Cov pwm siv nyob rau hauv qhov kub thiab txias yog rhuab thiab cov neeg kho tshuab alternating kev ntxhov siab ua rau qaug zog tawg ntawm cov khoom. Siv molybdenum los yog molybdenum raws li alloy nrog me me coefficient ntawm thermal expansion, muaj zog thermal conductivity thiab zoo kub kub lub zog yuav ua tau zoo heev prolong cov kev pab cuam lub neej ntawm tuag. Thaum lub tuam txhab gkn ntawm UK tuag cov khoom zoo xws li cov ntaub ntawv saib, lub neej kev pabcuam tuaj yeem ncav cuag 5000 zaug, feem ntau 3000 zaug. Nyob rau hauv cov kabmob ntau lawm, tungsten phaj, tungsten crucible thiab molybdenum crucible txais molybdenum alloy pwm, uas yog 15 zaug ntev dua li qub high-speed steel thiab bearing steel pwm.

Thaum isothermal forging lub refractory superalloy, molybdenum alloy tuag yuav siv tau ntawm 1200 ℃. Vim nws lub siab tawv thiab siab txias thiab kub qaug zog, molybdenum raws li alloy feem ntau yog siv los ntsaws thiab tuag ntawm seamless yeeb nkab tho tshuab, thiab nws lub neej yog ntau pua lub sij hawm ntev dua li ntawm 3Cr2W8V tuag steel. Molybdenum daim ntawv muab faib ua lub teeb molybdenum ntawv (PCC) thiab molybdenum ntawv (GCC).

Cov yam ntxwv ntawm daim ntawv molybdenum yog tias nws tuaj yeem tswj cov xim, qhov loj me, cov yam ntxwv saum npoo, dispersion, rheology, thixotropy thiab siv lead ua daim ntawv. Ntxiv mus, molybdenum daim ntawv muaj cov tshuaj purity siab, muaj zog tshuaj inertia thiab zoo thermal stability, thiab yuav tsis decompose hauv qab 400 ℃. Tsis tas li ntawd, daim ntawv molybdenum kuj muaj qhov zoo ntawm cov roj tsawg nqus, tsis tshua muaj zog, hnav tus nqi me me, tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis qab, zoo dispersion thiab lwm yam.
