I roto i te hangarau moana o te ao, ko te haumaru me te pono e whakawhirinaki nui ana ki te mahi ā-pūkaha o ngā pereti maitai e whakamahia ana mō ngā hanganga waka, ngā papaaho moana, me ngā wāhanga o raro i te moana. I te haere tonu o ngā paerewa hanga kaipuke, ko ngā momo maitai pēnei iAH36, DH36, EH36, me ētahi atu pereti hanganga kaha teitei me whakatutuki i te pakari, te pumau, me te roa. I roto i ngā tukanga matua e tautuhi ana i ēnei āhuatanga miihini, he mea nui te mahi a ngā tikanga whakataurite me te tinei. Ka whakamahia e ngā kaihanga matua, tae atu ki a sakysteel, ngā hangarau maimoatanga wera matatau hei whakarite i te kaha me te mahi tino pai i roto i ia pereti e tukuna ana ki te umanga.
Ka tūhuratia e tēnei tuhinga te whakapai ake a ngā tukanga whakataurite me te tinei i ngā pereti maitai hanga kaipuke, ngā mātāpono hangarau kei muri i ia tikanga, me ngā tono e whakawhirinaki ana ki te kaha hanganga kua whakapaitia.
He Kupu Whakataki ki te Maimoatanga Wera i roto i te Rino Hanga kaipuke
Me tu atu te pereti maitai hanga kaipuke i ngā wero taiao me ngā wero miihini maha pērā i te pānga o te ngaru, ngā kawenga hihiri, te pakarukaru o te pāmahana iti, me te waikura. Hei whakatutuki i ēnei hiahia, ka whakamahia e ngā kaihanga ngā tikanga maimoatanga wera e whakapai ake ana i te hanganga o te witi, e whakanui ake ana i te ngāwari, me te whakapai ake i te pakari. Ko ngā tikanga e rua e tino whai hua ana mō te whakarei ake i te kaha me te ōritetanga o te hanganga ko te whakataurite me te tinei, ā, muri iho ko te whakamahana.
Ka awe ngā tukanga e rua i te hanganga moroiti o roto o te maitai, ka āwhina i ngā pereti hanga kaipuke kia mau tonu ngā āhuatanga ōrite ahakoa i raro i ngā āhuatanga moana kino.
He aha te Whakaōrite
Ko te whakaōrite he tikanga whakamahana e whakamahia whānuitia ana mō te maitai hanga kaipuke, inā koa mō ngā momo e hiahia ana kia pakari me te ōrite. Ko te tukanga ko te whakamahana i te maitai ki te pāmahana kei runga ake i tōna pūwāhi whakawhiti matua, i waenga i te 880 me te 950 nekehanga Celsius, kātahi ka tukuna kia whakamatao i te hau marino.
Ngā Kaupapa Matua o te Whakaōrite
-
Te whakapai ake i te rahi o te witi hei whakapai ake i te pakari
-
Te whakarei ake i te ngāwari me te āhua
-
Te whakakore i ngā ahotea toenga mai i te hurihuri
-
Te whakataurite i te hanganga moroiti o te maitai
-
Te whakapai ake i te āheinga whakarewa mā te whakataurite i te pakeke me te kaha
He tino whai hua te whakataurite mō ngā pereti e whakamahia ana i roto i ngā hanganga anga, ngā wāhanga papa, me te hanganga moana whānui ina hiahiatia te ōritetanga me te pono.
Ngā Huringa Hanganga Moroiti i te Wā Whakaōrite
Ina whakamahanahia te maitai ki te pāmahana ōrite, ka huri tōna hanganga kōhatu hei austenite. I te wā e whakamatao ana te hau, ka huri te austenite hei pearlite pai me te ferrite, ka hua ake he pai ake ngā āhuatanga miihini. Mā te hanganga moroiti kua whakatikatikaina ka hua ake:
-
Te kaha hua teitei ake
-
He pai ake te ātete pānga
-
He rite tonu te matotoru o te pereti
Ko tēnei whakapainga hanganga tētahi o ngā tino take e pai ake ai ngā wāhi hanga kaipuke ki ngā pereti kua whakaritea mō ngā wāhi e pāngia ana e ngā kawenga rerekē.
He aha te Whakamātao me te Whakamātao QT
Mā te tinei me te whakamahana, e mōhiotia whānuitia ana ko te QT, ka nui ake te kaha i te whakaōrite. Ka whakamahanahia te pereti maitai ki te pāmahana austenitizing, kātahi ka tere te whakamatao, mā te whakamahi i te wai, i ngā otinga polymer rānei. Mā tēnei whakamatao tere ka huri te austenite hei martensite, he āhua mārō, he kaha hoki.
I muri i te tineia, ka whakamahanatia te maitai i te pāmahana iti iho, i waenganui i te 500 me te 650 nekehanga Celsius, hei whakaiti i te pakarukaru me te whakahoki mai i te pakari.
Kei roto i te Tukanga QT
-
Te whakapūmau
-
Te tinei tere
-
Te whakamahana hei whakamamae i te ahotea
-
Te whakatikatika whakamutunga o ngā āhuatanga miihini
Ka whakamahia e ngā kaihanga pēnei i a sakysteel ngā oumu whakamahana aunoa hei whakarite i te tika me te ōritetanga o te tukatuka QT.
Te Whakarei Kaha mā te Whakaiti i te Ngako
Ka whai wāhi tika te tinei ki te whakapai ake i te kaha mā te hanga i tētahi hanganga moroiti martensitic. He tino pakari, he tino kaha hoki te Martensite, ā, he pai ngā pereti tinei mō ngā tono hanga kaipuke nui pēnei i:
-
Ngā pereti waka pakaru hukapapa
-
Ngā waewae papaaho o te moana
-
Ngā kōwae FPSO
-
Ngā kurupae amo kawenga teitei
-
Ngā taiao whakahaere pāmahana iti
Nā te huinga o te kaha teitei me te pakari pāmahana iti kua pai ake, he mea tino pai ngā pereti maitai QT mō ngā kaupapa hangarau moana uaua.
Ngā Painga Hanganga Moroiti o te Maimoatanga Wera QT
Ko ngā hua o te tukanga QT ko:
