Dab tsi yog qhov zoo ntawm amorphous thiab nanocrystalline khoom?

Amorphous thiab nanocrystalline cov ntaub ntawv muaj ntau qhov zoo dua lawv cov khoom siv hlau sib xws.

1. Siab zog thiab hardness

Amorphous alloys muaj cov qauv atomic tsis sib xws, uas ua rau lawv muaj zog dua thiab tawv. Lawv tuaj yeem tiv taus kev ntxhov siab ntau dua thiab tsis muaj deforming lossis tawg. Cov ntaub ntawv nanocrystalline kuj pom muaj zog ntau dua li lawv cov coarse-grained counterparts vim yog cov nplej me me thiab ntau dua dislocation ntom.

2. Txhim kho cov khoom sib nqus

Amorphous thiab nanocrystalline cov ntaub ntawv muaj cov khoom sib nqus zoo heev, xws li tsis tshua muaj coercivity, siab permeability, thiab siab magnetic saturation. Cov khoom no ua rau lawv zoo tagnrho rau ntau yam kev siv, xws li transformers thiab cov khoom siv hluav taws xob.

3. Txhim kho corrosion kuj

Amorphous thiab nanocrystalline cov ntaub ntawv tau txhim kho corrosion kuj vim lawv cov qauv atomic homogeneous, tsis muaj ib thaj tsam ntawm cov nplej, thiab qhov sib txawv ntawm qhov loj-rau-ntim. Qhov no ua rau lawv tsim nyog rau kev siv hauv ib puag ncig hnyav, xws li marine thiab aerospace industries.

4. Zog txuag hluav taws xob

Vim lawv cov khoom sib nqus tshwj xeeb, cov khoom siv amorphous thiab nanocrystalline muaj zog heev. Lawv tuaj yeem siv los ua cov khoom tseem ceeb hauv transformers, txo lub zog poob txog li 75% piv rau cov pa roj carbon monoxide cores.

5. Biocompatible

Qee cov amorphous alloys tau pom cov lus cog tseg hauv kev siv biomedical vim lawv cov biocompatibility thiab corrosion kuj. Piv txwv li, hlau-raws li amorphous alloys tau siv rau hauv kev cog hniav vim lawv lub zog siab, biocompatibility, thiab tsis tshua muaj magnetic susceptibility.

Hauv kev xaus, cov ntaub ntawv amorphous thiab nanocrystalline muaj ntau qhov zoo dua li cov khoom siv hlau sib xws, xws li lub zog siab dua thiab hardness, txhim kho cov khoom sib nqus, txhim kho corrosion, zog-efficiency, thiab biocompatibility. Cov khoom tshwj xeeb no ua rau lawv haum rau ntau daim ntawv thov hauv kev lag luam sib txawv, los ntawm electronics mus rau biomedicine.
