Vanhu vazhinji vanofunga kuti simbi isina tsvina haisi yemagineti, uye kazhinji vanoshandisa magineti kuona kana chigadzirwa chacho chiri simbi isina tsvina. Iyi nzira yekutonga haisi yesainzi.
Simbi isina simbi inogona kukamurwa kuita zvikamu zviviri zvinoenderana nechimiro pakamuri tembiricha: austenite uye martensite kana ferrite. Iyo austenitic mhando isiri-magineti kana isina kusimba magineti, uye iyo martensite kana ferritic mhando ine magineti. Panguva imwecheteyo, ese austenitic simbi isina tsvina inogona kunge isiri-magnetic chete muvacuum state, saka chokwadi chesimbi isina tsvina haigone kutongwa nemagineti chete.
Chikonzero nei austenitic simbi ine magineti: austenitic Stainless simbi pachayo ine face-centered cubic crystal structure, uye pamusoro peiyo chimiro iparamagnetic, saka iyo austenitic chimiro pachayo haisi magineti. Cold deformation ndiyo mamiriro ekunze anoshandura chikamu che austenite kuita martensite uye ferrite. Kazhinji kutaura, iyo deformation huwandu hwemartensite inowedzera nekuwedzera kweiyo inotonhora deformation huwandu uye kudzikira kweiyo deformation tembiricha. Kureva kuti, iyo yakakura kutonhora kushanda deformation, iyo yakawanda martensitic shanduko uye yakasimba iyo magineti zvinhu. Hot-formed austenitic Stainless steels anenge asiri magineti.
Matanho ekugadzirisa kuderedza permeability:
(1) Iyo kemikari yakagadzirwa inodzorwa kuti iwane yakagadzikana austenite chimiro uye kugadzirisa iyo magineti permeability.
(2) Wedzera zvinhu zvekugadzirira kurapwa kutevedzana. Kana zvichidikanwa, iyo martensite, δ-ferrite, carbide, nezvimwewo mu austenite matrix inogona kunyungudutswa zvakare neyakaomeswa mhinduro kurapwa kuita kuti chimiro chiwedzere kufanana uye kuve nechokwadi chekuti magineti permeability inosangana nezvinodiwa. Uye siya imwe margin yekuzotevera kugadzirisa.
(3) Gadzirisa maitiro uye nzira, wedzera mhinduro yekurapa kutevedzana mushure mekuumbwa, uye wedzera kutevedzana kwekunhonga kune nzira yekuita. Mushure mekunhonga, ita magineti permeability bvunzo kuti isangane nezvinodiwa zve μ (5) Sarudza akakodzera maturusi ekugadzirisa uye zvishandiso zvematurusi, uye sarudza ceramic kana carbide maturusi kudzivirira magineti permeability yeworkpiece kubva pakukanganiswa nemagineti echishandiso. Mukuita machining, chidimbu chidiki chekucheka chinoshandiswa zvakanyanya sezvinobvira kuderedza kuitika kwemartensitic shanduko inokonzerwa nekunyanya kudzvinyirira kudzvinyirira.
(6) Degaussing yekupedzisa zvikamu.
