Molybdenum lanthanum alloy Njirimara: Kedu ihe dị iche n’etiti molybdenum lanthanum (Mo-La) alloy na TZM molybdenum alloy?

Kedu ihe dị iche n’etiti molybdenum lanthanum (Mo-La) alloy na TZM molybdenum alloy?

Kedu ihe bụ molybdenum-lanthanum alloy? Molybdenum-lanthanum alloy bụ alloy nke mebere isi metal molybdenum na lanthanum trioxide dị ugbu a dị ka irighiri ihe gbasasịrị na matriks. Ọdịnaya nke La2O3 na alloy bụ n’ozuzu 0.5% ~ 5.0% (oke ntakiri). Iji

Site na nyocha na arụmọrụ dị elu nke okpomọkụ na usoro kwekọrọ na molybdenum-lanthanum alloy na TZM alloy na 1000 ~ 1800 ℃. Nsonaazụ gosiri na mgbe okpomọkụ dị ala karịa 1400 ℃, molybdenum-lanthanum alloy nwere a elu keukwu arụmọrụ nke ike na plasticity. Mgbe okpomọkụ karịrị ma ọ bụ hà nhata 1400 ℃, ike tensile nke molybdenum-lanthanum alloy na-ebelata, na plasticity nke molybdenum-lanthanum alloy na-ebelatakwa. Site na mmụba nke okpomọkụ ule, ike nkwụsị nke TZM alloy na-ebelata, ma plasticity nke TZM molybdenum alloy na-abawanye, nke bụ kpọmkwem ihe na-emegide molybdenum-lanthanum alloy.

N’otu oge ahụ, ma ọ bụ ike ma ọ bụ plasticity, TZM alloy tụnyere molybdenum-lanthanum alloy n’otu okpomọkụ. Nleba anya na microstructure na-egosi na ihe abụọ a molybdenum alloys na-amalite recrystallize na 1100 ℃ ma na-aga n’ihu na 1550 ℃, na ọka ha recrystallized na-egosi elongated Ọdịdị, nke dị iche na equiaxed grains na recrystallized ala nke dị ọcha molybdenum.

1. Okwu mmalite nke molybdenum lanthanum alloy

Molybdenum lanthanum alloy, nke a makwaara dị ka molybdenum okpomọkụ dị elu, ika MoLa, bụ nke molybdenum doped na obere mkpụrụ nke lanthanum trioxide (La2O3) iji mepụta ihe a na-akpọ nhazi eriri laminated. Nkịta microstructure a pụrụ iche nwere ike ịnọgidesi ike ọbụlagodi na okpomọkụ dị elu 2000ºC. Ya mere, molybdenum-lanthanum oxide nwere nguzogide na-akpụ akpụ ọbụlagodi n’ọnọdụ oke ojiji. Anyị na-ahazi ụdị alloys molybdenum n’ime akụkụ ọkụ dị oke ọkụ, dị ka ọta ọkụ na-ekpo ọkụ na-ekpo ọkụ, ụgbọ mmiri na-ekpo ọkụ na mgbakasị ahụ, wires ndị tọrọ atọ ma ọ bụ mkpuchi evaporator.
