Intshayelelo kwiiPropati zeNickel Titanium Alloy

I-Nitinol yi-alloy memory alloy. I-alloy yememori ye-Shape yi-alloy ekhethekileyo enokuthi ibuyisele ngokuzenzekelayo i-deformation yayo yeplastiki kwisimo sayo sokuqala kwiqondo lokushisa elithile, kwaye ineplastiki enhle.
Izinga lokwandiswa kwalo lingaphezulu kwe-20%, ubomi bokukhathala bufikelela kumaxesha angama-7 kwi-1 * 10, iimpawu zokudambisa ziphindwe ka-10 ngaphezu kwemithombo eqhelekileyo, kwaye ukuxhathisa ukubola kubhetele kunentsimbi yangoku yezonyango, ngoko inokuhlangabezana neemfuno ezahlukeneyo. ubunjineli kunye nezicelo zonyango, kwaye luhlobo lwemathiriyeli ebalaseleyo yokusebenza.
Ukongeza kumsebenzi wokukhumbula ubume obukhethekileyo, iialloyi zememori zineempawu ezibalaseleyo ezifana nokunganyangeki, ukumelana nomhlwa, ukudamba okuphezulu kunye nokunwebeka okukhulu.
(I) Uguqulo lweSigaba kunye neePropati zeNickel-Titanium Alloys
Njengoko igama libonisa, i-alloy ye-Ni-Ti yi-alloy yokubini eyenziwe nge-nickel kunye ne-titanium, ekhoyo izigaba ezibini ze-crystal structure, i-austenite kunye ne-martensite, ngenxa yokutshintsha kweqondo lokushisa kunye noxinzelelo lomatshini. Umyalelo wokuguqulwa kwesigaba se-Ni-Ti alloy xa ukupholisa isigaba sabazali (isigaba se-austenite) - isigaba se-R - isigaba se-martensite. Isigaba se-R si-rhombic, i-austenite yimeko xa iqondo lokushisa liphezulu (likhulu kunelinye: oko kukuthi, iqondo lokushisa apho i-austenite iqala), okanye i-de-loaded (imikhosi yangaphandle isusa i-Deactivation), i-cubic, inzima. Ubume buzinzile. Isigaba se-martensite sinobushushu obuphantsi (ngaphantsi kwe-Mf: oko kukuthi, ubushushu bokuphela kwe-martensite) okanye ukulayisha (kusebenze ngamandla angaphandle) xa i-state, i-hexagonal, i-ductile, iphindaphinda, i-stable stable, i-deformation.
(B) iipropati ezikhethekileyo ze-nickel-titanium alloy
1, iimpawu zememori yokumila (inkumbulo yokwakheka)
2. Ukuqina kwe-Superelasticity
3, Uvakalelo kutshintsho lobushushu kumqolo womlomo.
4. Ukuchasa ukuMhlwa:
5, Anti-toxicity:
I-6, i-Soft orthodontic force
7. Iipropati ezilungileyo zokufunxa ukothuka
