Nitinol Memory Sawb

Chipnano muaj cov nplooj ntawv Nitinol (Ti-Ni Alloy nplooj ntawv, cov duab nco alloy strips) nrog cov ntsiab lus Af sib txawv, tso cai rau kev hloov kho ntawm cov alloy muaj pes tsawg leeg, kev kho cua sov, qhov chaw tiav, load platform thiab tensile lub zog.

Peb lub cim xeeb ntev ntev strips muaj nyob rau hauv tag nrho annealed los yog superelastic xeev, ua rau lawv zoo tagnrho rau stamping, sib sau, thiab lwm yam fabrication txheej txheem. Peb cov strips yog tsim los rau kev sib xyaw ua ke ntawm cov alloy, txhua yam thiab qhov loj me.

Shape memory alloys (SMA) yog suav tias yog ib qho ntawm cov khoom siv ntse tshaj plaws. Lub cim xeeb strips tuaj yeem muab cov kev daws teeb meem tshiab rau ntau daim ntawv thov hauv ntau qhov chaw (xws li actuators, biomedical applications, clamping systems, thiab lwm yam). Ntawm cov khoom lag luam muaj cov cim cim xeeb, nickel-titanium alloys sawv tawm rau lawv cov kev ua tau zoo thiab kev ntseeg tau.

Lub cim xeeb zoo tso cai rau NiTi alloys deform ntawm qee qhov kub thiab tom qab ntawd rov qab mus rau lawv cov duab qub thaum rhuab rau lawv qhov kev hloov pauv kub. Cov nyhuv no yog tshwm sim los ntawm kev hloov pauv ntawm cov khoom siv los ntawm monoclinic martensite qauv ntawm qhov kub thiab txias mus rau lub cubic austenite qauv ntawm qhov kub thiab txias. Ntxiv nrog rau cov duab nco alloys ua los ntawm Nitinol, peb kuj tuaj yeem muab cov khoom tsim los ntawm cov duab nco alloys ua los ntawm TiNiCu thiab TiNiNb.
