He aha nā ʻano kila kila he Magnetic?

Ua ʻike ʻia ke kila kila no kona kūpaʻa i ka pala a me kona ʻano maʻalahi, e lilo ia i mea nui i nā ʻoihana e like me ke kūkulu ʻana, ke kaʻa, ka hana ʻana i ka meaʻai, a me nā lako lapaʻau. ʻO kahi nīnau maʻamau, inā he magnetic ke kila kila. Aia ka pane i ka papa kikoʻī a me kona ʻano kūloko.

1. Ke hoʻomaopopo nei i nā ʻano hana liʻiliʻi kila kila

Ua hoʻokaʻawale ʻia nā kila kila i ʻelima mau ʻohana nui e pili ana i ko lākou microstructure:

Ke kila kila Austenitic (ʻAʻole Magnetic ma ke ʻano maʻamau)

  • ʻAno: Kūpika Kikowaena Maka (FCC)
  • Nā Papa Maʻamau: 304, 316, 310, 321
  • Nā Hiʻohiʻona: Kū'ē maikaʻi loa i ka palaho, ductility kiʻekiʻe, ʻaʻole hiki ke hoʻopaʻa ʻia e ka mālama wela
  • ʻAno Magnetic: ʻAʻole magnetic i ke kūlana annealed; hiki ke lilo iki i magnetic ma hope o ka hana anu

Ke kila kila Ferritic (Makeneka)

  • ʻAno: Kupika Kikowaena Kino (BCC)
  • Nā Māka Maʻamau: 409, 430, 439
  • Nā Hiʻohiʻona: Kū'ē maikaʻi i ka palaho, conductivity wela kiʻekiʻe, kumukūʻai haʻahaʻa
  • ʻAno Magnetic: Magnetic ma nā kūlana āpau

Ke kila kila Martensitic (Makeneka)

  • ʻAno: Tetragonal i Kikowaena ʻia e ke Kino (BCT)
  • Nā Papa Maʻamau: 410, 420, 440A, 440C
  • Nā Hiʻohiʻona: Ikaika kiʻekiʻe, hiki ke mālama ʻia i ka wela, kūpaʻa kūpono i ka palaho
  • ʻAno Magnetic: Magnetic ikaika

Ke kila kila Duplex (Mākēneki hapa)

  • ʻAno: FCC + BCC i hui pū ʻia (Austenitic + Ferritic)
  • Nā Papa Maʻamau: 2205, S31803, 2507
  • Nā Hiʻohiʻona: Ikaika maikaʻi loa, kūpaʻa i ka haki ʻana o ka palaho
  • ʻAno Magnetic: ʻAno magnetic hapa ma muli o ka ʻike ferritic

Paʻakikī o ka ua (PH) Kila kila (Makeneka)

  • Nā Māka Maʻamau: 17-4PH, 15-5PH
  • Nā Hiʻohiʻona: Ikaika kiʻekiʻe a me ka paʻakikī ma hope o ka mālama ʻana i ka wā ʻelemakule
  • ʻAno Magnetic: Magnetic ma hope o ka mālama ʻana i ka wela

2. No ke aha he Magnetic kekahi mau kila kila?

Aia nā waiwai magnetic o ke kila kila ʻole i kona ʻano kristal. ʻO nā kila Austenitic (e like me 304 a me 316) he ʻano i kākoʻo ʻole i ka magnetism, ʻoiai ʻo nā kila ferritic a me martensitic he mau ʻano e kūlike me nā kahua magnetic.

Hiki i nā kila kila ʻole-magnetic ke hoʻomohala i ka magnetism hapa ma muli o ka deformation mechanical e like me ke kulou ʻana, ka ʻōwili ʻana, a i ʻole ka machining (hana anu).

3. Nā Waiwai Magnetic ma ka Papa

Papa ʻAno Mākēneki Nā memo
304 ʻAustenitic ʻAʻole (ʻUʻuku ma hope o ka hana anu) ʻO ka papa kila kila maʻamau
316 ʻAustenitic No Nā noi kai, kū'ē i nā chlorides
430 Ferritic ʻAe Hoʻohana ʻia i loko o nā mīkini kuke a me nā mea hoʻonani
410 Martensitic ʻAe Nā mea hana pahi, nā ʻau hoʻopā
17-4PH Ka Paʻakikī ʻana o ka Ua ʻAe Ikaika ma hope o ka ʻelemakule; hoʻohana ʻia i ka aerospace
2205 ʻElua pālua hapa Ke kūpaʻa maikaʻi loa i ka haki ʻana o ka palaho

4. Kahi e Koʻikoʻi ai nā Waiwai Magnetic

He mea nui ka hoʻomaopopo ʻana inā he magnetic ke kila kila i kekahi mau ʻoihana:

Nā noi e koi ana i ke kila kila ʻaʻole Magnetic

  • Nā mea hana lapaʻau (kūlike me ka MRI)
  • Nā pā uila a me ka pale ʻana
  • Ka hana ʻana i ka meaʻai a me nā lāʻau lapaʻau

Nā noi e pono ai ke kila kila kila

  • Nā motika a me nā mea hana uila
  • Nā mea hoʻokaʻawale makeneka
  • Nā ʻāpana mīkini e like me nā puka umu

5. Pehea e hoʻāʻo ai no ka Magnetism

Aia kekahi mau ala maʻalahi e hoʻoholo ai inā he magnetic ke kila kila:

  • Hoʻāʻo Magnet:E hoʻohana i ka magnet maʻamau e ʻike ai inā e pipili.
  • Mea ʻike hopena Hall:Ana i ka ikaika o ke kahua magnetic.
  • Mea kālailai mea:Hoʻoholo i ka haku mele a me ke ʻano o ka metala.

6. Hiki i ka Hana Anu ke hoʻoulu i ka Magnetism?

ʻAe. Hiki i ka hana anu ke hoʻololi i ke ʻano kristal o nā kila kila austenitic a hoʻolauna i kahi pane magnetic hapa. ʻO ka annealing (hoʻomehana a laila hoʻomaʻalili mālie) e hōʻemi i kēia magnetism akā hiki ke hoʻopilikia i ka ikaika a i ʻole ke kūpaʻa ʻana i ka pala.

7. Ke koho ʻana i ka papa kūpono no ka Magnetic Sensitivity

I ke koho ʻana i ke kila kila:

  • E hoʻohana i ka 304 a i ʻole 316 no nā pono non-magnetic
  • E hoʻohana i ka 430, 410, a i ʻole 17-4PH kahi e pono ai ke ʻano magnetic
  • E koho i nā papa duplex ke ʻae ʻia ka ikaika kiʻekiʻe a me ka magnetism kaulike

8. Papa Hōʻuluʻulu Manaʻo: ʻAno Magnetic o nā ʻAno Kila Kila

ʻAno Nā Laʻana Mākēneki? Nā Manaʻo
ʻAustenitic 304, 316 ʻAʻole (ʻUʻuku ma hope o ka hana anu) ʻOi aku ka pale ʻana i ka pala
Ferritic 430, 409 ʻAe Kūpono ke kālā, makeneka
Martensitic 410, 420, 440C ʻAe Paʻakikī kiʻekiʻe a me ka ikaika
ʻElua pālua 2205, 2507 hapa Ikaika kiʻekiʻe a me ke kūpaʻa i ka palaho
Ke kila PH 17-4PH ʻAe Hoʻohana ʻia i loko o ka aerospace a me nā ʻāpana ukana kiʻekiʻe

9. Hopena

ʻAʻole nā ​​papa kila kila āpau he magnetic. ʻO nā papa Austenitic e like me 304 a me 316 he mau mea maʻamau ʻaʻole magnetic a kūpono no nā noi e koi ana i ka hoʻopilikia magnetic liʻiliʻi. He magnetic nā papa Ferritic a me martensitic a he mea pono no nā noi mechanical a me nā noi kūkulu. Hāʻawi nā kila Duplex a me PH i kahi kaulike o nā waiwai a me ka magnetism kaulike.

ʻO ka hoʻomaopopo ʻana i kēia mau ʻokoʻa e hiki ai iā ʻoe ke koho i ka mea kūpono no kāu noi - inā paha e koi ana i nā waiwai magnetic a i ʻole e pono e pale aku iā lākou.

E hoʻokaʻaʻike iā Sakysteel

Inā ʻaʻole ʻoe maopopo i ka papa kila kila kūpono no kāu noi, e kelepona mai iā mākou no ka ʻōlelo aʻoaʻo loea:
