Tshwj xeeb, AMS 4911 tsom rau titanium alloy nplooj ntawv thiab daim hlau.
Yam khoom twg yog AMS 4911?
AMS 4911 yog tsim los ntawm ib qho tshwj xeeb titanium alloy, uas yog Ti-6Al-4V, uas yog cais raws li alpha-beta titanium alloy. Cov hlau no muaj kwv yees li 90 feem pua titanium, 6 feem pua aluminium, thiab 4 feem pua vanadium, nrog rau cov khoom me me xws li hlau thiab oxygen. Ti-6Al-4V yog ib qho ntawm feem ntau siv titanium alloys vim nws zoo heev zog-rau-qhov hnyav piv, corrosion kuj, thiab kub stability.
AMS 4911 qib twg?
AMS 4911 poob rau qib 5 kev faib tawm ntawm titanium alloys, raws li tau hais los ntawm ASTM (American Society for Testing and Materials). Qib 5 titanium alloys, tseem hu ua Ti-6Al-4V, yog siv dav hauv ntau yam lag luam, suav nrog aerospace, tshuaj ua haujlwm, marine, thiab kev siv kho mob. Lawv muab kev sib xyaw ua ke ntawm lub zog siab, lub teeb yuag, thiab tshwj xeeb corrosion kuj, ua rau lawv haum rau qhov xav tau ib puag ncig.
Dab tsi yog cov khoom ntawm AMS 4911?
AMS 4911 titanium nplooj ntawv thiab daim hlau nthuav tawm ntau yam khoom tsim nyog, suav nrog:
Lub zog muaj zog: AMS 4911 muaj lub zog tensile zoo heev thiab lub zog tawm los, tso cai rau nws tiv taus cov khoom hnyav thiab kev ntxhov siab.
Tsawg ntom ntom: titanium alloys muaj qhov ntom ntom, li ntawm ib nrab ntawm cov hlau, uas ua rau lawv qhov hnyav.
Corrosion Resistance: AMS 4911 tiv taus corrosion, txawm tias nyob rau hauv ib puag ncig hnyav xws li dej hiav txwv thiab cov kua qaub. Cov cuab yeej no ua rau nws tsim nyog rau cov ntawv thov uas xav tau lub sijhawm ntev.
High Temperature Stability: Cov alloy tuav nws cov khoom siv kho mob ntawm qhov kub siab, ua kom nws ua tau zoo nyob rau hauv qhov kub thiab txias.
Biocompatibility: Ti-6Al-4V yog biocompatible, txhais tau tias nws tsis muaj tshuaj lom rau cov ntaub so ntswg. Cov cuab yeej no ua rau nws zoo tagnrho rau kev cog ntoo thiab cov cuab yeej phais.
AMS 4911 tuab npaum li cas?
AMS 4911 titanium nplooj ntawv thiab daim hlau muaj nyob rau hauv ntau yam thicknesses xws li nyias foils mus rau thicker daim hlau. Cov thicknesses tshwj xeeb tuaj yeem sib txawv nyob ntawm qhov xav tau ntawm daim ntawv thov lossis cov neeg siv khoom tshwj xeeb. Feem ntau cov thicknesses siv nyob rau hauv aerospace thiab industrial daim ntaub ntawv feem ntau yog nyob ntawm 0 016 nti (0.41 mm) mus rau 4 nti (101.6 mm) los yog ntau tshaj.
AMS 4911 vs AMS 4928
Thaum AMS 4911 thiab AMS 4928 ob leeg poob rau hauv AMS series thiab cuam tshuam raucov ntaub ntawv titanium, lawv txawv ntawm lawv cov specifications. AMS 4928 tshwj xeeb tsom rau cov kev cai rau titanium alloy tuav, forgings, thiab rings. Nws txhais cov tshuaj muaj pes tsawg leeg, txhua yam khoom, kev kho cua sov, thiab lwm yam khoom tshwj xeeb rau cov khoom no. Hauv qhov sib piv, AMS 4911 cuam tshuam rau titanium alloy nplooj ntawv, sawb, thiab cov ntaub ntawv phaj raws li tau tham ua ntej.
AMS piv txwv
AMS tsev neeg suav nrog ntau yam kev qhia tshwj xeeb rau cov khoom sib txawv siv hauv kev lag luam aerospace. Qee qhov piv txwv ntawm lwm yam kev qhia AMS suav nrog:
