1j77 Soft Magnetic Alloy Waya Ni77Mo4Cu5

Nkọwa dị mkpirikpi:

Ni77Mo4Cu5 bụ nickel-ígwè magnetik alloy, nwere ihe dị ka 80% nickel na 20% ígwè ọdịnaya. Emepụtara ya na 1914 site n'aka ọkà mmụta sayensị Gustav Elmen na ụlọ nyocha ekwentị Bell, ọ bụ ihe ama ama maka ikike ndọta ya dị elu, nke na-eme ka ọ baa uru dị ka isi ihe ndọta na ngwa eletriki na ngwa eletrọnịkị, yana kwa na mkpuchi magnetik iji gbochie oghere ndọta. Azụmahịa permalloy alloys na-enwekarị ikike ikike nke gburugburu 100,000, ma e jiri ya tụnyere ọtụtụ puku maka ígwè nkịtị.
Na mgbakwunye na ikike dị elu, ihe ndọta ya ndị ọzọ bụ mmanye dị ala, dị nso magnetostriction efu, yana nnukwu magnetoresistance anisotropic. Magnetostriction dị ala dị oke mkpa maka ngwa ụlọ ọrụ mmepụta ihe, na-enye ohere iji ya mee ihe na fim ndị dị mkpa ebe nrụgide na-agbanwe agbanwe ga-eme ka nnukwu mgbanwe dị ukwuu na akụrụngwa magnetik. Iguzogide eletriki Permalloy nwere ike ịdịgasị iche ruo 5% dabere na ike na ntụzịaka nke oghere ndọta etinyere. Permalloys na-enwekarị ihe owuwu cubic kristal gbadoro anya na ihu ya nwere ihe dị ka 0.355 nm n'akụkụ mkpokọta nickel nke 80%. A mwepu nke permalloy bụ na ọ bụghị nnọọ ductile ma ọ bụ na-arụ ọrụ, ya mere ngwa chọrọ ọtụtụ shapes, dị ka magnetik ọta, mere nke ndị ọzọ elu permeability alloys dị ka mu metal. A na-eji Permalloy mee ihe na laminations transformer na isi ndekọ magnetik.
Ni77Mo4Cu5 a na-ejikarị na ụlọ ọrụ redio-eletrọnịkị, ngwa nkenke, njikwa ime na sistemụ njikwa akpaka.
