Nitinol chimiro chekuyeuka alloy. Shape memory alloy ndeye yakakosha alloy iyo inogona kudzoreredza yayo yega deformation yepurasitiki kune yayo yepakutanga chimiro pane chaiyo tembiricha, uye ine yakanaka plasticity.
Kuwedzera kwayo kuri pamusoro pe20%, hupenyu hwekuneta hunosvika 7 nguva dze1 * 10, hunhu hwekunyorovesa hwakareba kakapetwa ka10 kupfuura zvitubu zvakajairika, uye kushora kwayo kuri nani pane simbi yemazuva ano yekurapa, saka inogona kusangana nezvinodiwa zvakasiyana. engineering uye zvekurapa zvikumbiro, uye imhando yezvinhu zvakanakisa zvinoshanda.
Pamusoro peiyo yakasarudzika chimiro chekurangarira basa, ndangariro alloys zvakare ane akanakisa hunhu senge kupfeka kuramba, corrosion resistance, high damping uye super elasticity.
(I) Chikamu Chekushandura uye Zvivakwa zveNickel-Titanium Alloys
Sezvinoratidzwa nezita racho, Ni-Ti alloy ibhinari alloy inoumbwa nickel uye titanium, iyo iripo maviri akasiyana ekristaro chimiro chechikamu, austenite uye martensite, nekuda kwekuchinja kwekushisa uye mechanical pressure. Kurongeka kwechikamu chekushandurwa kweNi-Ti alloy kana kutonhora iri chikamu chevabereki (austenite chikamu) - R chikamu - martensite chikamu. The R phase is rhombic, austenite ndiyo mamiriro apo tembiricha yakakwira (yakakura kupfuura yakafanana: kureva, tembiricha panotanga austenite), kana de-loaded (kunze kwemauto anobvisa Deactivation), cubic, yakaoma. Chimiro chakanyanya kugadzikana. Chikamu chemartensite chinenge chakaderera tembiricha (isingasviki Mf: ndiko kuti, tembiricha yekupera kwemartensite) kana kurodha (yakagadziriswa nekunze kwemasimba) apo iyo nyika, hexagonal, ductile, inodzokorora, isina kugadzikana, yakanyanya kukonzeresa deformation.
(B) yakakosha zvimiro zvenickel-titanium alloy
1, chimiro chendangariro maitiro (chimiro chendangariro)
2, Superelasticity (superelasticity)
3, Sensitivity kune tembiricha shanduko mumuromo mhango.
4, Corrosion resistance:
5, Anti-toxicity:
6, Soft orthodontic force
7 、Zvakanaka zvekuvhunduka zvimisikidzo
