Molybdenum lanthanum aluminium: Waa maxay faraqa u dhexeeya molybdenum lanthanum (Mo-La) alloy iyo TZM molybdenum alloy?

Waa maxay faraqa u dhexeeya molybdenum lanthanum (Mo-La) alloy iyo TZM molybdenum alloy?

Waa maxay daawaynta molybdenum-lanthanum? Daawaha Molybdenum-lanthanum waa daawaha ka kooban molybdenum bir ah saldhigga iyo lanthanum trioxide oo jooga sida qaybo kala firdhiyey shaxanka. Nuxurka La2O3 ee ku jira daawaha guud ahaan waa 0.5% ~ 5.0% (jajab tiro). Ku

Iyada oo loo marayo cilmi-baarista waxqabadka heerkulka sare iyo qaabka u dhigma ee molybdenum-lanthanum alloy iyo TZM alloy at 1000 ~ 1800 ℃. Natiijooyinku waxay muujinayaan in marka heerkulku ka hooseeyo 1400 ℃, daawaynta molybdenum-lanthanum waxay leedahay waxqabad sare oo dhamaystiran oo xoog iyo caag ah. Marka heerkulku ka weyn yahay ama le’eg yahay 1400 ℃, awoodda xajinta ee daawaynta molybdenum-lanthanum waa hoos u dhacdaa, balaastigga molybdenum-lanthanum alloy sidoo kale wuu yaraadaa. Kordhinta heerkulka tijaabada, xoogga xajinta ee TZM alloy ayaa hoos u dhacaya, laakiin balaastikada TZM molybdenum alloy waxay kordhisaa, taas oo si sax ah uga soo horjeeda daawaynta molybdenum-lanthanum.

Isla mar ahaantaana, haddii ay tahay xoog ama caag, TZM alloy waxaa lagu barbar dhigaa molybdenum-lanthanum alloy heerkul isku mid ah. Indho-indheynta qaab-dhismeedku waxay muujinayaan in labadan alaabo ee molybdenum ay bilaabaan inay dib u soo celiyaan 1100 ℃ oo ay sii wadaan 1550 ℃, iyo miraha recrystalized waxay muujinayaan qaab-dhismeed dheer, taas oo ka duwan midhaha isku midka ah ee gobolka recrystallized ee molybdenum saafi ah.

1. Hordhac molybdenum lanthanum alloy

Molybdenum lanthanum alloy, oo sidoo kale loo yaqaan molybdenum heerkulka sare, sumadda MoLa, waxay ka samaysan tahay molybdenum doped oo ay ku jiraan qaybo yar oo lanthanum trioxide (La2O3) si ay u sameeyaan waxa loogu yeero qaabdhismeedka fiber laminated. Qaab-dhismeedkan yar-yar ee gaarka ah wuxuu ahaan karaa mid deggan xitaa heerkul u sarreeya 2000 ° C. Sidaa darteed, molybdenum-lanthanum oxide waxay leedahay iska caabin gurguurta xitaa marka lagu jiro xaaladaha isticmaalka daran. Inta badan waxaanu u farsamaynnaa daawaynta molybdenum-ka oo kale qaybo foorno kuleylkeedu sarreeyo, sida gaashaanka kulaylka foornada faakuumka, doomaha jeexjeexa iyo annealing, fiilooyinka go’doonsan ama gariiradaha uumiga.

2. Faa’iidooyinka molybdenum lanthanum alloy:

Heerkulka dib-u-crystalization sare;

Qaab-dhismeedka qayb-dheeraaday wuxuu hagaajin karaa ductility;

Iska caabbinta oksaydhka oo xooggan;

Iska caabin gurguurta oo sarreeya.

3. Heerkulka dib-u-crystalization: 1400℃ ~ 1500℃.
