Ka taea te whakamahana i te maitai kore waikura?

Ko te maitai kore waikura tētahi o ngā rauemi e whakamahia whānuitia ana i te ao, e mōhiotia ana mō tōna ātete ki te waikura, tōna kaha, me tōna āhua ma. Engari he pātai noa e pātaihia ana i roto i ngā porowhita ahumahi me te hangarau ko:Ka taea te whakamahana i te maitai kore waikura?Ko te whakautu he āe—engari kei te momo maitai kore waikura me ngā hua e hiahiatia ana.

I roto i tēnei tuhinga, ka tūhuratia e mātou ko ēhea ngā maitai kore waikura ka taea te whakamahana, ngā momo tikanga whakamahana rerekē, me te pānga o tēnei ki te mahi i roto i ngā tono o te ao tūroa.

Te Mārama ki ngā Momo Kowiri tira

Hei mārama ki ngā āheinga maimoatanga wera, he mea nui kia mōhio ki ngā momo matua o te maitai kore waikura:

1. Kowiri tira Austenitic(hei tauira, 304, 316)
   Koinei ngā momo tino noa, e mōhiotia ana mō te ātete pai ki te waikura engarikāore e taea te whakapakeke mā te maimoatanga weraKa taea anake te whakapakari mā te mahi matao.

2. Kowiri tira Martensitic(hei tauira, 410, 420, 440C)
   Ko ēnei mākaka taea te whakamahanahei whakatutuki i te mārō me te kaha teitei, he rite ki ngā maitai waro.

3. Kowiri tira Ferritic(hei tauira, 430)
   He iti noa te kaha whakapakeke o ngā momo Ferritic, ā,kāore e taea te whakapakeke rawa mā te maimoatanga weraHe maha ngā wā e whakamahia ana ēnei i roto i ngā whakapaipai me ngā taputapu motuka.

4. Kowiri tira takirua(hei tauira, 2205, S31803)
   He hanganga ranu o te austenite me te ferrite ēnei maitai. Ahakoaka taea te whakamahana i te otinga, ko rātoukāore e tika ana mō te whakapakekemā roto i ngā tikanga tuku iho mō te maimoatanga wera.

5. Te whakapakeketanga o te ua Te maitai kore waikura(hei tauira, 17-4PH / 630)
   Ka taea te whakamahana i ēnei ki ngā taumata kaha tino tiketike, ā, e whakamahia whānuitia ana i roto i ngā mahi rererangi me ngā hanganga kawenga teitei.

Ngā Tikanga Maimoatanga Wera mō te Kowiri tira

Ko te tukanga whakamahana mō te kowiri tira he whakamahi i ngā huringa whakamahana me te whakamatao hei whakarerekē i te hanganga moroiti me ngā āhuatanga hangarau. Kei raro nei ngā tukanga whakamahana e whakamahia whānuitia ana mō ngā momo kowiri tira:

1. Te whakamahana

Kaupapa:Ka whakamamae i te ahotea o roto, ka whakangawari i te maitai, ā, ka whakapai ake i te ngāwari.
Ngā Māka e Pā Ana:Ngā maitai kowiri tira Austenitic, ferritic, takirua.

Ko te whakamahana i te maitai ki te pāmahana o te 1900–2100°F (1040–1150°C) kātahi ka whakamatao wawe, i roto i te wai, i te hau rānei. Mā tēnei ka whakahokia mai te ātete ki te waikura, ā, ka māmā ake te hanga, te mīhini rānei i te rauemi.

2. Te whakapakeketanga

Kaupapa:Ka whakanui ake i te kaha me te ātete ki te kakahu.
Ngā Māka e Pā Ana:Ngā maitai kowiri tira Martensitic.

Ko te whakapakeketanga me whakamahana te rauemi ki te pāmahana teitei (tata ki te 1000–1100°C), ā, muri iho ka tinei tere i roto i te hinu, i te hau rānei. Ka hua ake he hanganga mārō engari he pakarukaru, ā, i te nuinga o te wā ka whakamahanahia hei whakatika i te pakeketanga me te pakari.

3. Te whakamahana

Kaupapa:Ka whakaiti i te pakarukaru i muri i te whakapakeketanga.
Ngā Māka e Pā Ana:Ngā maitai kowiri tira Martensitic.

I muri i te whakapakeketanga, ka whakamahana anōtia te maitai ki tētahi pāmahana iti iho (150–370°C) hei whakamahana, ka paku whakaiti i te pakeketanga engari ka whakapai ake i te pakari me te ngāwari o te whakamahi.

4. Te Whakapakari o te Ua (Te Kaumātuatanga)

Kaupapa:He kaha teitei, he ātete pai hoki ki te waikura.
Ngā Māka e Pā Ana:Ngā maitai kore waikura PH (hei tauira, 17-4PH).

Kei roto i tēnei tukanga te maimoatanga otinga, ā, muri iho ka whakatōkia i ngā pāmahana iti iho (480–620°C). Mā tēnei ka taea e ngā wāhanga te eke ki ngā taumata kaha tino teitei me te iti o te hē.

He aha te take e whakamahanahia ai te maitai kore waikura?

He maha ngā take e whiriwhiri ai ngā kaihanga me ngā miihini i te maimoatanga wera ki te maitai kore waikura:

• Te Whakanuia o te Pakarimō ngā taputapu tapahi, ngā mata, me ngā wāhanga ātete-kakahu

• Kaha Whakapai akemō ngā wāhanga hanganga i roto i te rererangi me te motuka

• Whakaora i te ahoteai muri i te whakarewa, i te mahi matao rānei

• Te Whakapaipai i te Hanganga Moroitihei whakaora i te ātete ki te waikura me te whakapai ake i te āheinga hanga

Mā te whakamahana i te kounga tika o te maitai kore waikura ka nui ake te ngāwari o te hoahoa me te whakamahinga, me te kore e whakararu i te tiaki i te waikura.

Ngā Wero o te Whakamahana i te Kowiri tira

Ahakoa he pai, me āta whakahaere te whakamahana o te maitai kore waikura:

• Te wera rawaka arahi pea ki te tipu o te witi me te ngoikore o te pakari

• Te ua o te kāpiratērā pea ka whakaiti i te ātete waikura i roto i ngā maitai austenitic mēnā kāore i te tika te whakamatao

• Te whakapōturi me te pikotērā pea ka puta mēnā kāore i te ōrite te whakamatao

• Te waikura me te tauine o te matame whakapūkara, me whakakore rānei i muri i te maimoatanga

Koia te mea nui kia mahi tahi me ngā kaiwhakarato rauemi mātau me ngā tohunga maimoatanga wera. Isakysteel, ka tukuna e mātou ngā rauemi kowiri tira mata me te tautoko hangarau hei whakarite i te tukatuka tino pai.

Ahakoa e hiahia ana koe ki te ātete ki te waikura, ki te kaha, ki te ātete rānei ki te kakahu, ko te whiriwhiri i te kounga maitai kore waikura kua tukatukahia ki te wera te mea nui mō te roa o te mahi.

Whakamutunga

Āe, he kowiri tirakēneme whakamahanatia ki te wera—i runga i te momo me te putanga e hiahiatia ana. Ahakoa kāore e taea te whakapakeke i ngā momo austenitic me te ferritic mā te whakamahana, ka taea te whakamahana i ngā momo whakapakeke martensitic me te precipitation kia eke ki te kaha me te pakeke teitei.

I te wā e whiriwhiri ana i te maitai kore waikura mō tāu tono, he mea nui kia whakaarohia ehara i te mea ko tōna ātete ki te waikura anake engari me te mea hoki me whai maimoatanga wera kia pai ai tana mahi.
