Ferrotitanium alloy

Ferrotitanium yog ib qho nruab nrab alloy ntawm titanium thiab hlau, siv los ua tus neeg ua haujlwm huv rau cov hlau. Ferrotitanium yog cov hlau alloy nrog cov ntsiab lus titanium ntawm 20% -27%.

Khoom Description

Titanium yog suav hais tias yog cov hlau tsis tshua muaj vim tias nws tau tawg hauv qhov xwm txheej thiab nyuaj rau rho tawm. Tab sis nws cov txheeb ze nplua nuj nyob rau hauv tag nrho cov ntsiab lus qeb kaum, ferrotitanium alloy, yog ib tug high-zog lub teeb alloy, muaj ntau yam kev siv nyob rau hauv txhua yam, raws li ib tug deoxidizer, alloy additives, nyob rau hauv lub steelmaking txheej txheem ntawm deoxidation muaj peev xwm ntau dua silicon. , manganese, thiab tuaj yeem txo ingot segregation, txhim kho qhov zoo ntawm ingot, txhim kho cov txiaj ntsig, thaum nce lub zog ntawm cov hlau, corrosion kuj thiab stability; Siv nyob rau hauv stainless hlau, cuab yeej hlau, tuaj yeem txhim kho kev ua haujlwm ntawm cam khwb cia hlau;

intro

►Lub invention nthuav tawm ib qho ferrotitanium alloy thiab ib txoj kev npaj ntawm no

Cov muaj pes tsawg leeg ntawm ferrotitanium alloy los ntawm huab hwm coj feem pua suav nrog titanium hmoov 20% ~ 50%, carbon hmoov 6% ~ 15%, praseodymium hmoov 0.2% ~ {{1{ {12}}}}.6%, tooj liab hmoov0.1% ~ 0.3%, npib tsib xee hmoov 0.1% ~ 0.2%, cov hmoov hlau seem, tag nrho cov huab hwm coj feem pua yog 100%; Txoj kev npaj ntawm ferrotitanium alloy yog raws li hauv qab no: ua ntej, cov khoom siv raw yog raws li qhov hnyav feem pua, tom qab ntawd cov ntaub ntawv raw yog feem ntau sifted, sifted raw cov ntaub ntawv yog tov thiab av, thiab thaum kawg nias thiab sintering yog nqa. tawm los npaj ib qho ferrotitanium alloy; Lub ferrotitanium alloy ntawm lub invention tsis tau tsuas yog siab ceev, siab melting point, tab sis kuj superior coj kuj, thiab muaj peev xwm ua tau zoo raws li kev lag luam xav tau rau ferrotitanium alloy.

►Alloying cov ntsiab lus tuaj yeem muab faib ua peb pawg raws li lawv cov txiaj ntsig ntawm theem kev hloov pauv kub:

① Cov ntsiab lus uas ruaj khov rau theem thiab nce qib kev hloov pauv kub yog cov khoom ruaj khov, suav nrog txhuas, carbon, oxygen thiab nitrogen. Ntawm lawv, aluminium yog lub ntsiab alloying ntawm titanium alloy, uas muaj qhov pom tseeb ntawm kev txhim kho lub zog ntawm cov hlau nyob rau hauv chav tsev kub thiab kub kub, txo qhov tshwj xeeb lub ntiajteb txawj nqus thiab nce elastic modulus.

② Cov ntsiab lus stabilize theem thiab txo cov theem hloov pauv kub yog cov khoom ruaj khov, uas tuaj yeem muab faib ua hom isomorphic thiab eutectoid. Cov qub muaj molybdenum, niobium, vanadium thiab lwm yam; Cov tom kawg muaj chromium, manganese, tooj liab, hlau, silicon thiab lwm yam.

③ Cov ntsiab lus uas tsis tshua muaj kev cuam tshuam rau theem hloov pauv kub yog qhov nruab nrab, xws li zirconium thiab tin.Oxygen, ammonia, carbon thiab hydrogen yog lub ntsiab impurities ntawm titanium alloys. Oxygen thiab nitrogen muaj cov solubility loj nyob rau theem, uas muaj qhov tseem ceeb ntxiv dag zog rau titanium alloy, tab sis nws txo cov plasticity. Nws feem ntau tau teev tseg tias cov ntsiab lus ntawm oxygen thiab nitrogen hauv titanium yog qis dua {{0}}.15 ~ 0.2% thiab 0.04-0.05%. , raws. Lub solubility ntawm hydrogen nyob rau hauv ib theem yog tsawg heev, thiab ntau heev hydrogen yaj nyob rau hauv titanium alloys yuav tsim hydrides, ua rau cov alloy nkig. Feem ntau, cov ntsiab lus hydrogen hauv titanium alloys yog tswj hauv qab 0.015%. Lub dissolution ntawm hydrogen nyob rau hauv titanium yog reversible thiab yuav raug tshem tawm los ntawm lub tshuab nqus tsev annealing.
