Molybdenum alloys

Molybdenum ua lub hauv paus ntxiv rau lwm cov ntsiab lus thiab muaj pes tsawg leeg ntawm cov hlau tsis muaj hlau. Lub ntsiab alloying ntsiab yog titanium, zirconium, hafnium, tungsten thiab tsawg lub ntiaj teb ntsiab. Titanium, zirconium, hafnium ntsiab tsis tsuas yog nyob rau hauv molybdenum alloy khoom siv ntxiv dag zog rau cov nyhuv, kom tswj tau cov hlau tsis tshua muaj kub plasticity, tab sis kuj tsim kom ruaj khov, diffuse faib ntawm carbide theem, txhim kho cov alloy lub zog thiab recrystallization kub. Molybdenum alloy muaj thermal conductivity zoo, hluav taws xob conductivity thiab tsawg coefficient ntawm expansion, siab zog ntawm high kub (1100 ~ 1650 degree), tshaj tungsten yooj yim rau txheej txheem. Nws tuaj yeem siv los ua daim phiaj thiab anode ntawm electron tube, cov khoom txhawb nqa ntawm lub teeb pom kev zoo, thiab siv los ua cov pwm tuag-casting thiab extrusion pwm, spacecraft qhov chaw thiab lwm yam. Vim lub molybdenum alloy muaj qhov kub thiab txias brittleness thiab vuam brittleness, thiab kub kub yooj yim rau oxidize, yog li nws txoj kev loj hlob yog txwv. Kev tsim khoom ntawm molybdenum alloys muaj molybdenum-titanium-zirconium, molybdenum-tungsten thiab molybdenum-tsis tshua muaj lub ntiaj teb alloys, daim ntawv thov ntau dua yog thawj qeb. Molybdenum alloys feem ntau yog ntxiv dag zog rau cov khoom siv ntxiv dag zog, nag lossis daus ntxiv dag zog thiab ua haujlwm hardening. Molybdenum alloy daim hlau, strips, foils, raj, rods, xov hlau thiab profiles tuaj yeem tsim los ntawm kev ua cov yas, uas tuaj yeem ua rau lawv lub zog thiab txhim kho qhov kub thiab txias.

Molybdenum yog ib qho tseem ceeb hauv cov hlau thiab alloys. Feem ntau siv molybdenum-muaj cov nqi suav nrog molybdenum hlau, ferromolybdenum, thiab qee zaum molybdenum oxide concentrates tuaj yeem siv los txo qis thiab smelt molybdenum-muaj steel qib. Lub ntuj reserves ntawm molybdenum nyob rau hauv lub ntiaj teb crust yog 19 lab tons, thiab mineable reserves yog 8.6 lab tons.
