Lub hauv paus ntsiab lus ntawm kev nco alloy:
Nws yog feem ntau ntseeg tias cov duab rov qab nco yuav tshwm sim thaum lub cim xeeb alloys hloov los ntawm complex rhombic siv lead ua qauv rau cov qauv cubic siv lead ua yooj yim. Thaum cov duab nco alloy rov qab los rau nws cov duab qub, nws nrog lub zog loj. Cov nitinol alloy yog siab li 60 kg square mm, uas yog ntau dua li lub zog ntxiv thaum pib deformation. Feem ntau hais lus, nws tuaj yeem ncav cuag kaum npaug ntawm qhov qub deformation, uas txhais tau hais tias lub zog tso zis ntau dua li lub zog nkag.
Cov kws tshawb fawb tsis tuaj yeem piav qhia qhov no. Physicist Rosal tau hais tias: "Tsis muaj ib yam dab tsi tsis ncaj ncees lawm nrog cov cai ntawm cov thermodynamics, tab sis cov cai no tsis haum rau nitinol?". Tam sim no, ntau tus kws tshawb fawb ntseeg tias yog vim li cas vim li cas lub cim xeeb alloys tuaj yeem rov qab tau lawv cov duab qub yog vim lub luag haujlwm ntawm "kev nco". Qhov "nco qhov tseem ceeb" yog muab los ntawm kev kawm ntawm lub zog dawb thiab ntim kev sib raug zoo hauv cov txheej txheem hloov pauv.
