Kodi chitsulo chosapanga dzimbiri ndi maginito?

Anthu ambiri amaganiza kuti chitsulo chosapanga dzimbiri si maginito, ndipo nthawi zambiri amagwiritsa ntchito maginito kuti adziwe ngati chitsulocho ndi chitsulo chosapanga dzimbiri. Njira yoweruzira imeneyi sigwirizana ndi sayansi.
Chitsulo chosapanga dzimbiri chingagawidwe m'magulu awiri molingana ndi kapangidwe kawo kutentha kwa chipinda: austenite ndi martensite kapena ferrite. Mtundu wa austenitic ndi wopanda maginito kapena wofooka maginito, ndipo mtundu wa martensite kapena ferritic ndi maginito. Panthawi imodzimodziyo, zitsulo zonse zosapanga dzimbiri za austenitic zimatha kukhala zopanda maginito pokhapokha mu malo opanda kanthu, kotero kuti zitsulo zosapanga dzimbiri sizingayesedwe ndi maginito okha.
Chifukwa chomwe chitsulo cha austenitic chili ndi maginito: chitsulo chosapanga dzimbiri cha austenitic chokha chimakhala ndi mawonekedwe amtundu wa cubic crystal, ndipo pamwamba pake ndi paramagnetic, kotero mawonekedwe a austenitic palokha si maginito. Cold deformation ndi chikhalidwe chakunja chomwe chimatembenuza gawo la austenite kukhala martensite ndi ferrite. Nthawi zambiri, kuchuluka kwa mapindikidwe a martensite kumawonjezeka ndi kuchuluka kwa kuzizira komanso kuchepa kwa kutentha kwa deformation. Ndiko kunena kuti, kukulitsa kuzizira kogwira ntchito, kusinthika kwa martensitic komanso mphamvu yamaginito. Zitsulo zosapanga dzimbiri zopangidwa ndi austenitic zimakhala pafupifupi zopanda maginito.

Njira zochepetsera permeability:
(1) Mankhwalawa amayendetsedwa kuti apeze dongosolo lokhazikika la austenite ndikusintha maginito permeability.
(2) Wonjezerani zinthu zokonzekera kukonzekera ndondomeko. Ngati ndi kotheka, martensite, δ-ferrite, carbide, etc. mu austenite masanjidwewo akhoza kusungunukanso ndi olimba njira mankhwala kupanga dongosolo yunifolomu ndi kuonetsetsa kuti permeability maginito akukwaniritsa zofunika. Ndipo siyani malire ena kuti mukonzekere.
(3) Sinthani ndondomeko ndi njira, onjezerani njira yothetsera chithandizo pambuyo pa kuumba, ndikuwonjezera ndondomeko ya pickling panjira. Pambuyo pickling, chitani maginito permeability mayeso kukwaniritsa zofunika μ (5) Sankhani zida zoyenera zogwirira ntchito ndi zida zogwiritsira ntchito, ndikusankha zida za ceramic kapena carbide kuti muteteze maginito permeability ya workpiece kuti asakhudzidwe ndi maginito a chida. Popanga makina, kudula kochepa kumagwiritsidwa ntchito momwe mungathere kuti muchepetse kusinthika kwa martensitic komwe kumayambitsa kupsinjika kwakukulu.
(6) Kuchotsa mbali zomaliza.
