He Magnetic anei ke kila kila?

Hoʻolauna

Ua ʻike nui ʻia ke kila kila no kona kūpaʻa i ka pala a me kona helehelena maikaʻi, akā he nīnau i nīnau pinepine ʻia penei:He makeneka anei ke kila kila?ʻAʻole pololei ka pane—e pili ana ia i kaʻanoa meʻano kristalo ke kila kila. Ma kēia alakaʻi, e ʻimi mākou i nā waiwai magnetic o nā ʻano kila kila like ʻole, e wehewehe i nā kuhi hewa, a kōkua i nā ʻenekinia, nā mea kūʻai, a me nā DIYers e hana i nā koho naʻauao.

He aha ka mea e hana ai i kahi mea Magnetic?

Ma mua o ka luʻu ʻana i ke kila kila, e nānā kākou i nā mea e hoʻoholo ai inā he magnetic kahi mea. He mea iamakenekainā hiki ke huki ʻia i kahi magnet a i ʻole magnetized. Hana ʻia kēia i ka wā e loaʻa ai ka meanā electrons i hui ʻole ʻiaa me kahiʻano kristale hiki ai i nā ʻāpana magnetic ke hoʻonohonoho pono.

Ua hoʻokaʻawale ʻia nā mea i ʻekolu mau ʻano magnetic:

• Ferromagnetic(ikaika loa ka makeneka)

• Paramagnetic(mākēneki nāwaliwali)

• Diamagnetic(ʻaʻohe makeneka)

Ke ʻAno o ke Kila Kūlohelohe: Ferrite, Austenite, Martensite

He kila kila ʻolehao huilaaia ka chromium a i kekahi manawa nickel, molybdenum, a me nā mea ʻē aʻe. Aia kona waiwai magnetic i konaʻano liʻiliʻi, e hāʻule ana i loko o kēia mau ʻano:

1. Ke kila kila Austenitic (ʻAʻole Magnetic a i ʻole Magnetic nāwaliwali)

• Nā Papa Maʻamau304, 316, 310, 321

• ʻAno: Kūpika Kikowaena Maka (FCC)

• Mākēneki?: ʻAʻole maʻamau ka magnetic, akā ʻo ka hana anu (e laʻa, ke kulou ʻana, ka mīkini ʻana) hiki ke hoʻoulu i ka magnetism iki.

ʻO nā kila kila Austenitic nā ʻano maʻamau i hoʻohana ʻia i nā lako kuke, nā paipu, a me nā mea lapaʻau ma muli o ko lākou kūpaʻa maikaʻi loa i ka pala a me ka ductility.

2. Ke kila kila Ferritic (Makeneka)

• Nā Papa Maʻamau: 430, 409,446

• ʻAno: Kupika Kikowaena Kino (BCC)

• Mākēneki?: ʻAe, he makeneka nā kila ferritic.

Hoʻohana pinepine ʻia lākou i nā ʻāpana kaʻa, nā mīkini home, a me nā noi ʻoihana kahi i lawa ai ke kūpaʻa kaulike i ka pala.

3. Ke kila kila Martensitic (Makeneka)

• Nā Papa Maʻamau: 410, 420, 440C

• ʻAnoʻO ke kino-kikowaena Tetragonal (BCT)

• Mākēneki?: ʻAe, he ikaika ka makeneka o kēia mau mea.

Ua ʻike ʻia nā kila Martensitic no ko lākou paʻakikī a hoʻohana pinepine ʻia i nā pahi, nā mea ʻokiʻoki, a me nā ʻāpana turbine.

He Magnetic anei ke kila kila 304 a i ʻole 316?

ʻO kēia kekahi o nā nīnau i ʻimi nui ʻia. Eia kahi hoʻohālikelike wikiwiki:

No laila, inā ʻoe e ʻimi neikila kila ʻaʻole makeneka, 304 a me 316 kāu mau koho maikaʻi loa—ʻoiai i ko lākou kūlana annealed.

No ke aha he mea nui inā he Magnetic ke kila kila?

He mea nui ka hoʻomaopopo ʻana inā he magnetic kahi kila kila no:

• Nā lako hana meaʻaikahi e hiki ai i ka magnetism ke hoʻopilikia i nā mīkini.

• Nā mea lapaʻaue like me nā mīkini MRI, kahi i koi ʻia ai nā mea ʻaʻole magnetic.

• Nā lako mea kūʻai aku: no ka launa pū ʻana me nā mea hoʻopili magnetic.

• Hana ʻoihana: kahi e loli ai ke ʻano o ka weldability a i ʻole ka mīkini ma muli o ke ʻano.

Pehea e hoʻāʻo ai i ka Magnetism kila kila

No ka nānā ʻana inā he makeneka ke kila kila:

1. E hoʻohana i kahi magnet– E hoʻopili iā ia ma ka ʻili. Inā pili pono ia, he makeneka ia.

2. E hoʻāʻo i nā wahi like ʻole– Hiki i nā ʻāpana i hoʻoheheʻe ʻia a hana anu ʻia ke hōʻike i ka magnetism hou aʻe.

3. E hōʻoia i ka māka– I kekahi manawa, hoʻohana ʻia nā koho ʻē aʻe haʻahaʻa ke kumu kūʻai me ka ʻole o ka lepili.

Nā kaula uea kila kila ʻole magnetic

Ua hana mākou i nā hoʻāʻo ʻole-magnetic ma nā kaula uea kila kila o nā diameters a me nā mea like ʻole e hōʻoia i ka mālama ʻana i nā kūlana permeability haʻahaʻa-magnetic i koi ʻia i nā noi koʻikoʻi e like me nā lumi MRI, ka hoʻohana ʻana i ka pūʻali koa, a me nā mea hana pololei.

Hōʻike kēia hōʻike wikiō i kā mākou kaʻina hoʻāʻo magnetic, e hōʻoia ana i kā mākou mau kaula—i hana ʻia mai nā papa e like me ke kila kila 316L a me 304—mālama i nā waiwai non-magnetic ʻoiai ma hope o ke kūkulu ʻia ʻana a me ka hana ʻana.

Hiki i ke kila kila ke lilo i Magnetic i ka hala ʻana o ka manawa?

ʻAe.Hana anu(kūlou, hoʻokumu, mīkini) hiki ke hoʻololi i ka microstructure o ke kila kila austenitic a hoʻolaunanā waiwai ferromagneticʻAʻole kēia manaʻo ua loli ke ʻano o ka mea—ʻo ia hoʻi ua lilo iki ka ʻili i mea makeneka.

Hopena

No laila,He makeneka anei ke kila kila?ʻO ka pane:ʻO kekahi, ʻaʻole kekahi.Aia ia i ke ʻano a me ka mālama ʻana.

• Austenitic (304, 316)ʻAʻole magnetic i ke ʻano annealed, iki magnetic ma hope o ka hana anu.

• Ferritic (430)a meMartensitic (410, 420)Mākēneki.

I ke koho ʻana i kahi kila kila no kāu noi, e noʻonoʻoʻo kona kūpaʻa i ka pala a me nā waiwai magneticInā he mea nui ka ʻole o ka magnetism, e hōʻoia me kāu mea hoʻolako a hoʻāʻo pololei paha i ka mea.
