Nitinol: Hlau lossis tsis-hlau

I. Kev sib xyaw thiab cov khoom ntawm nickel-titanium alloy

Nickel-titanium alloy yog ib qho alloy uas muaj npib tsib xee, titanium thiab lwm yam khoom, uas tuaj yeem muab faib ua ob pawg: nickel-based nickel-titanium alloy thiab titanium raws nickel-nickel alloy. Nitinol alloy muaj lub cim xeeb zoo thiab lub cim xeeb zoo, thiab muaj cov yam ntxwv ntawm ductility, kub siab zog thiab zoo corrosion kuj. Yog li ntawd, nws yog dav siv hauv aerospace, khoom siv kho mob, kev tsim tsheb thiab lwm yam kev lag luam.

 

Thib ob, cov khoom siv hlau ntawm nickel-titanium alloy

Nitinol zoo ib yam li hlau hauv lub cev thiab tshuaj lom neeg. Nws muaj cov khoom siv hluav taws xob zoo, thermal conductivity thiab toughness ntawm cov hlau, tab sis nws cov microstructure muaj ntau cov tshuaj amorphous, yog li nws tuaj yeem deformed thiab rov qab tau ntau zaus, qhia txog cov duab nco thiab superelasticity zoo ib yam li hlau.
