Khoom Taw qhia
Peb cov ntawv titanium-nickel nco alloy yog tsim raws li ASTM F 2063, tus qauv siv rau cov khoom siv kho mob thiab cov khoom siv phais. Cov khoom muaj peev xwm ntawm kev hloov pauv theem ntawm ob lub qauv siv lead ua sib txawv, tso cai rau nws hloov pauv thaum rhuab mus rau qhov kub thiab txias. nws cov duab thiab kho nws cov duab qub. Thaum unidirectional zoo nco alloys yog haum rau siv nyob rau hauv sensors, bidirectional zoo nco alloy daim hlau yog zoo tagnrho rau actuators uas yuav hloov cov duab nyob rau hauv ob qho tib si cov lus qhia.
Cov hom alloys muaj xws li nitinol (nickel titanium), tooj liab-aluminium-nickel alloys, thiab hlau-platinum alloys, thiab lwm yam. Cov lus qhia tshwj xeeb suav nrog cov khoom siv tshuaj, lub cev, kev siv tshuab thiab metallurgical rau wrought npib tsib xee-titanium rods, flat-rolled khoom thiab cov hlab uas muaj 54.5% mus rau 57. Cov kev cai no siv rau cov khoom siv dov los ntawm 6 mus rau 130 hli (0.24 txog 5.12 ntiv tes) nyob rau hauv txoj kab uas hla los yog thickness nyob rau hauv lub annealed mob.
Titanium-nickel alloy yog equiatomic intermetallic compound (Ti50Ni50). Cov tswv yim alloy muaj pes tsawg leeg yog Ti-(49-51)%Ni (atomic feem). Titanium-nickel intermetallic compounds yog ductile thiab tuaj yeem ua haujlwm kub thiab txias. Tus nqi ua haujlwm txias yog 10% mus rau 25%, thiab qhov kub ntawm recrystallization yog 500 txog 600 degree. Titanium-nickel alloy muaj qhov zoo heev corrosion kuj nyob rau hauv high-temperature theem, zoo damping nyob rau hauv qis-kub theem, thiab cim xeeb zog thiab superelasticity nyob rau hauv lub theem hloov chaw. Cov khoom ntawm titanium-nickel alloy yog raws li nram no:

Txoj kev ua ntawm titanium-nickel alloy daim hlau muaj ntau theem:
Ua ntej, cov ntaub ntawv raw yog rhuab mus rau qhov kub thiab txias thiab alloyed rau hauv ib homogeneous sib tov.
Qhov sib tov yog melted thiab cam khwb cia rau hauv cov duab thiab loj, nyob ntawm seb yuav tsum tau daim ntawv thov.
Cov phaj yog ua tiav los ntawm kev kub siab forging thiab kev kho cua sov kom ua tau raws li cov lus qhia tshwj xeeb thiab ua tiav qhov sib xws.
Qhov zoo ntawm titanium-nickel nco alloy daim hlau:
Kev siv thaj chaw:
Cov khoom siv kho mob: Nitinol alloys tau siv dav hauv kev tsim cov stents, coj cov xov hlau, clamps thiab lwm yam khoom siv kho mob, tshwj xeeb tshaj yog hauv kev phais plawv thiab vascular interventional. Lawv superelasticity thiab cov duab nco los tso cai rau cov cuab yeej no yooj yim nkag mus rau hauv lub cev thiab nthuav dav lossis xav tias ntau cov duab nyob rau hauv cov xwm txheej tshwj xeeb.
Aerospace: Nickel-titanium alloy yog siv nyob rau hauv lub aerospace teb los tsim elastic Cheebtsam, servos, li qub, thiab lwm yam. Nws super elasticity thiab siab responsiveness pab kom nws ua lub luag haujlwm tseem ceeb hauv qee qhov chaw tshwj xeeb.
Automotive Industry: Siv nyob rau hauv kev tsim cov valve springs, nres tshuab, shock absorbers thiab lwm yam automotive qhov chaw los txhim kho kev ua tau zoo thiab braking.
Cov khoom siv hluav taws xob: Nickel-titanium alloy tuav yog siv los tsim cov khoom siv hauv cov khoom siv hluav taws xob xws li micro-motors thiab hluav taws xob tsav.
