1j77 Waya yeMagnetic Alloy yakapfava Ni77Mo4Cu5

Tsananguro pfupi:

Ni77Mo4Cu5 isimbi ine magnetic alloy ine nickel-iron, ine 80% nickel uye 20% iron. Yakatangwa muna 1914 nenyanzvi yefizikisi Gustav Elmen kuBell Telephone Laboratories, inozivikanwa nekukwanisa kwayo kushandisa magnetic permeability yakawanda, izvo zvinoita kuti ishande semagineti core material mumagetsi nemagetsi, uye zvakare mu magnetic shielding kudzivirira magnetic fields. Commerce permalloy alloys inowanzova ne magnetic permeability inosvika 100,000, zvichienzaniswa ne simbi yakajairika inosvika zviuru.
Pamusoro pekukwanisa kupenya zvakanyanya, zvimwe zvinhu zvayo zvemagineti zvinosanganisira kumanikidzwa kwakaderera, kumanikidzwa kwemagneto pedyo ne zero, uye kushivirira kukuru kwe anisotropic magnetoresistance. Kudzikira kwemagnetostriction kwakakosha kumashandisirwo emaindasitiri, zvichibvumira kuti ishandiswe mumafirimu matete uko kumanikidzwa kwakasiyana kwaizokonzera shanduko huru muhunhu hwemagineti. Kudzivirira kwemagetsi kwePermalloy kunogona kusiyana kusvika 5% zvichienderana nesimba uye kutungamira kwesimba remagineti rinoshandiswa. Permalloys inowanzo kuve nechimiro chekristaro checubic centered face ine lattice constant inosvika 0.355 nm pedyo ne nickel concentration ye80%. Dambudziko repermalloy nderekuti haina kupfava zvakanyanya kana kushanda, saka mashandisirwo anoda maumbirwo akakura, akadai se magnetic shield, anogadzirwa nemamwe ma alloys ane kupenya kwakanyanya akadai se mu metal. Permalloy inoshandiswa mu transformer laminations uye magnetic recording heads.
Ni77Mo4Cu5 inoshandiswa zvakanyanya muindasitiri yemagetsi eredhiyo, zvishandiso zvine hungwaru, kudzora kuri kure uye system yekudzora otomatiki.
