1. Cov ntoo ntshiab MolybdenUM
Cov paib ntshiab MolybdenueMuaj npe rau lawv lub siab melting taw tes (2610 degree), zoo heev thermal thiab zoo- kub lub zog, thiab lwm yam teb, thiab lwm thaj teb.
Txawm li cas los xij, lawv cov recrystallization kub yog cov qes (kwv yees li 1000 degree). Ntshiab Molybdenum daim hlau muaj qee lub zog ntawm chav tsev sov, tab sis raws li qhov kub thiab txias (siab dua 1000 degree), lub zog txo qis me ntsis. Tom qab recrystallization, impurities zoo li yuav ua rau ntawm cov ciaj ciam av, thiab cov nplej zom ua kom muaj kev ntxhib, ua rau muaj kev poob qis, ua rau} - kev ua haujlwm kub. Cov paib Molybdenum ntshiab tau nkab thiab nyuaj rau khoov lossis stamp nyob rau chav sov. Qhov no txwv nws daim ntawv thov nyob rau hauv ib puag ncig huab.
Chaw Thov:
Ntshiab Molybdenum daim hlau yog haum rau tsawg - kub (<1100°C) or non-load-bearing applications, such as ordinary sintering boats, supports, electron tube auxiliary components, high-temperature furnace hot zones, and photovoltaic modules.
2. Molybdenum - lanthhanum alloys phaj (Mola Alloy phaj)
Molybdenum - lanthhanum alloads daim hlauMuaj zog los ntawm doping a molybdenum matrix nrog 0.5% -5.0% Iperseled Lanthanide Trioxide (La₂o₃) cov lus, ib hom oxide disperming ntxiv.
La₂o₃ hais kom zoo rau cov qoob loo ntau, muaj zog heev ntxiv cov khoom siv kub thiab txhim kho cov khoom kub {{kub ruaj khov.
Cov yam ntxwv ua tau:
- high recrystallization kub:1400 DEGree -1500 degree, deb siab dua li ntshiab Molybdenum; Txawm tias tom qab siab - kub sov, nws tswj cov qauv nplej zoo, zam kev puag.
- chav tsev kub tov:Zoo heev. Txawm nyob hauv lub xeev recrystallized, nws ua kom zoo dua ductility dua li ntshiab Molybdenum thiab TZM, saib xyuas cov txheej txheem xws li Stamping thiab khoov thiab khoov.
{{0- high - kub lub zog:Zoo dua molybdenum, tab sis feem ntau qis tsis meej zog tshaj tzm alloy.
{{0- zoo heev creep resistance:Tswj cov txheej txheem stability txawm nyob ntawm 1800 degree.
Chaw Thov:
Suitable for long-term service at ultra-high temperatures (>1400 degree), xws li iav zoo nkauj hluav taws xob, iav stinesring pas dej cua sov, cov khoom siv tshuab cua sov, thiab lwm yam siab {}} kub cov khoom kub.
3. TZM Alloy Phaj (Titanium- zirconium - molybdenum alloy phaj)
Tzm Molybdenum Alloy PhajSiv ib txoj kev ua kom muaj zog ntxiv dag zog ntxiv los ntawm kev sib ntxiv ntawm TI, ZR, thiab C. Nws cov kev ua tau zoo tshaj plaws uas yog Molybdenum {}} lanthhant alloys. Nrog nws cov unparalleled siab - lub zog thiab cov cheem siv ntau tshaj li {}} qhov kub txheej txheem.
Cov yam ntxwv ua tau:
{{0- high - kub lub zog thiab hardness:Zoo tshaj plaws ntawm peb. Los ntawm chav tsev kub mus dhau 1400 degree, nws lub zog, nws lub zog yog siab dua li ntshiab Molybdenum thiab molybdenum {l}} lanthanum alloys.
- recrystallization kub:Heev heev, nrog recrystallization kub ntawm 1150℃thiab ua tiav qhov kub ntawm 1250 degree, thib ob tsuas yog rau Molybdenum {}} lanthhant alloys.
-} cov neeg nkag:Qhov zoo tshaj plaws, zoo tagnrho rau cov khoom sib xyaw ua ke kom siab rau siab - kub, hnyav thauj khoom.
- chav tsev kub tov:Kuj tsis zoo. Although better than recrystallized pure molybdenum, it is inherently brittle, making secondary processing (such as bending) difficult.
