Molybdenum lanthanum alloy Properties: Menene bambanci tsakanin molybdenum lanthanum (Mo-La) gami da TZM molybdenum gami?

Menene bambanci tsakanin molybdenum lanthanum (Mo-La) gami da TZM molybdenum gami?

Menene molybdenum-lanthanum alloy? Molybdenum-lanthanum gami wani gami ne wanda ya ƙunshi tushe na ƙarfe molybdenum da lanthanum trioxide waɗanda ke kasancewa a matsayin barbashi tarwatsa a cikin matrix. Abubuwan da ke cikin La2O3 a cikin gami shine gabaɗaya 0.5% ~ 5.0% (ƙasassun taro). Zuwa

Ta hanyar bincike a kan high zafin jiki yi da kuma m tsarin na molybdenum-lanthanum gami da TZM gami a 1000 ~ 1800 ℃. Sakamakon ya nuna cewa lokacin da zafin jiki ya kasance ƙasa da 1400 ℃, molybdenum-lanthanum gami yana da babban aikin ƙarfin ƙarfi da filastik. Lokacin da zafin jiki ya fi ko daidai da 1400 ℃, ƙarfin juzu’i na molybdenum-lanthanum gami yana raguwa, kuma filastik na molybdenum-lanthanum gami kuma yana raguwa. Tare da karuwar zafin gwajin, ƙarfin ƙarfin ƙarfin TZM yana raguwa, amma filastik na TZM molybdenum alloy yana ƙaruwa, wanda shine daidai da akasin molybdenum-lanthanum alloy.

A lokaci guda, ko yana da ƙarfi ko filastik, ana kwatanta alloy na TZM tare da molybdenum-lanthanum alloy a daidai zafin jiki. Abubuwan lura da microstructure sun nuna cewa waɗannan nau’ikan nau’ikan molybdenum guda biyu sun fara yin recrystallize a 1100 ℃ kuma suna ci gaba zuwa 1550 ℃, kuma hatsin da aka yi musu recrystallized suna nuna tsarin elongated, wanda ya bambanta da nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in nau’in ingantattun kayan aikin sun fara recrystallize a XNUMX ℃ kuma suna ci gaba zuwa XNUMX ℃.

1. Gabatarwa zuwa molybdenum lanthanum gami

Molybdenum lanthanum gami, kuma aka sani da babban zafin jiki molybdenum, alamar MoLa, an yi shi da molybdenum doped tare da ƙaramin adadin lanthanum trioxide (La2O3) don samar da abin da ake kira tsarin fiber laminated. Wannan microstructure na musamman na iya zama barga ko da a yanayin zafi sama da 2000 ° C. Saboda haka, molybdenum-lanthanum oxide yana da juriya mai raɗaɗi ko da a cikin matsanancin yanayin amfani. Mu galibi muna sarrafa irin waɗannan galoli na molybdenum zuwa sassa na tanderu mai zafi, kamar garkuwar murhun wuta, sintering da annealing kwale-kwalen, wayoyi da ke danne ko kuma na’urorin da ake fitarwa.

2. Amfanin molybdenum lanthanum gami:

Mafi girman recrystalization zafin jiki;

The elongated barbashi tsarin iya inganta ductility;

Ƙarfin oxidation mai ƙarfi;

Juriya mafi girma.
