Kua puta ake ngā maitai kore waikura austenitic tino matatau hei tetahi o ngā rauemi tino pono me te matatau i roto i te ao whakarewa. E mōhiotia ana mō tō rātou ātete ki te waikura, te kaha teitei, me te kaha ki te tu atu i ngā pāmahana tino kino, kua noho ēnei koranu hei mea nui i roto i ngā ahumahi pēnei i te tukatuka matū, te rererangi, me ngā tono moana. Ko te whanaketanga o te maitai kore waikura austenitic tino pai he haerenga whakamīharo o te auahatanga me te whanaketanga pūtaiao. I roto i tēnei tuhinga, ka tūhuratia e mātou te hītori, ngā āhuatanga, ngā tono, me te heke mai o ngā maitai kore waikura austenitic tino pai, me te whakamārama anō hoki me pēhea teSAKY STEELkei te whakarato tonu i ngā rauemi kounga teitei mō ngā tono ahumahi uaua.
He aha te maitai kore waikura austenitic tino pai?
Ko te maitai kore waikura austenitic tino kaha te mahi, he momo maitai kore waikura austenitic tino pai. He mea motuhake tēnei momo maitai nā tōna ātete pai ki te waikura, inā koa i roto i ngā taiao waikawa nui, i ngā taiao whai rawa rānei i te hauota. Ko ngā maitai kore waikura austenitic te mea e kitea whānuitia ana e tōna hanganga karaihe poraka mata-pokapū (FCC), e whakarato ana i te pakari me te ngāwari pai i ngā pāmahana iti.
He nui ake te ihirangi koranu o ngā maitai kore waikura austenitic, he nui te nikara, te molibdenum, me te hauota i roto i ētahi wā, kia nui ake ai te ātete ki te waikura, te pakaru ahotea, me te waikura pāmahana teitei. Nā ēnei whakarei ake ka tino pai ngā maitai kore waikura austenitic mō ngā tono e hiahia ana ki te mahi tino pai i raro i ngā āhuatanga tino kino.
Te Whanaketanga Tōmua o te Kowiri tira Austenitic
I te tīmatanga o te rautau 20 i whakawhanakehia tuatahitia ai te maitai kore waikura austenitic, he tohu tēnei i tētahi whanaketanga nui i roto i te ao pūtaiao rauemi. Ko ngā maitai kore waikura austenitic taketake, pērā i ngā tohu 304 me te 316, i hangaia hei whakakotahi i te ātete waikura o te maitai kore waikura me te pakari me te ngāwari o te maitai waro. I rongonui whānuitia ēnei nā te mea he pai te hanga, he ātete ki te waikura, me te ngāwari o te hanga.
Heoi, he iti noa iho ngā herenga o ēnei maitai austenitic o mua i te wā e pāngia ana e ngā taiao tino waikura, e ngā pāmahana tino kino rānei. Nā tēnei i ārahi ngā kairangahau me ngā tohunga whakarewa ki te rapu i ngā otinga matatau ake, ā, i te mutunga iho ka hua ake ko te hanganga o ngā maitai kore waikura super austenitic.
Ngā Kaupapa Matua i roto i te Whakawhanaketanga o te Rino Kowiri tira Austenitic
Ngā tau 1950: Ngā Auahatanga me ngā Whakamātautau o Mua
I tīmata te kōrero mō te maitai kore waikura austenitic i ngā tau 1950 i te wā i tīmata ai ngā kaipūtaiao me ngā miihini ki te whakamātautau i ngā koranu ka pai ake te ātete ki te waikura o te poka me te kapiti, inā koa i roto i te umanga tukatuka matū. I arotahi ngā nganatanga tuatahi ki te whakanui ake i te ihirangi chromium hei whakapai ake i te ātete ki te waikura, engari kāore i ranea tēnei anake hei whakatutuki i ngā āhuatanga uaua o ngā taiao kaha, pērā i ngā mea e tūpono ana ki te wai moana me ngā matū waikawa.
Ko tētahi o ngā putanga tuatahi o te whanaketanga o te maitai kore waikura austenitic super ko te tāpiri i ngā taumata teitei ake o te nikara me te moriperenum, ā, i tino whakarei ake i te ātete o te rauemi ki te waikura pitting i puta mai i te hauhāora. Ko ēnei momo austenitic super tōmua, e kiia ana ko ngā "maitai kore waikura nikara-teitei", he taahiraa nui whakamua i roto i ngā rauemi ātete-waikura.
Ngā tau 1960: Te Tūranga o te Molybdenum me te Nitrogen
I te tekau tau atu i 1960, kua kitea e ngā kairangahau te hiranga o te molybdenum me te hauota ki te whakapakari i te ātete ki te waikura o ngā maitai kore waikura. I kitea te tino whai huatanga o te molybdenum ki te aukati i te waikura pitting, he momo waikura ā-rohe noa e puta ana i ngā taiao whai hauota, pērā i te wai moana me ngā matū ahumahi. I tetahi atu taha, i kitea te hauota hei whakapai ake i te kaha me te pakari o te koranu, kia kaha ake ai te ātete ki te pakaru o te waikura ahotea.
I tēnei wā, ka horapa haere ngā maitai kore waikura tino austenitic kei roto ko te molybdenum (i waenga i te 4-7%) me te hauota. Ka tīmata te rongonui o ēnei rauemi i roto i ngā ahumahi pēnei i te hanga hinu me te hau i tai, i reira ngā rauemi i pāngia e te ahotea nui me te taiao waikura.
Ngā tau 1970: Te Whanaketanga o ngā Reanga Super-Austenitic Tuatahi
I ngā tau 1970, i whakaurua mai ngā momo tuatahi o te maitai kore waikura super austenitic. I roto i ēnei ko ngā momo pēnei i te 904L, he 25% te nikara me te 4.5% te molibdenum, ā, i hangaia kia ātete ki te waikura o te poka me te kapiti. I whakaatuhia hoki e ēnei momo he ātete tino pai ki te waikawa whanariki me ētahi atu matū kaha, nā reira i pai ai mō te whakamahi i roto i ngā ahumahi tukatuka matū me te rongoā.
Ko te whanaketanga o ēnei koranu i tohu i te tīmatanga o te whakamahinga whānui o te maitai kore waikura austenitic i roto i ngā tono mahi teitei. Ko te kaha o te koranu ki te tu atu i ngā pāmahana teitei me ngā taiao kaha i waiho ai hei rauemi pai mō ngā ahumahi pēnei i te rererangi me te whakaputa hiko.
Ngā tau 1980: Ngā whanaketanga o te hanga me te hanganga koranu
I ngā tau 1980, i haere tonu te whanaketanga o ngā maitai kore waikura austenitic, nā ngā whanaketanga o ngā hangarau hanga me te hanganga koranu i akiaki. Nā te whakaurunga o ngā tikanga whakarewa me te whakarewa matatau i taea ai te whakaputa i ngā koranu ōrite ake me te kounga teitei ake, ā, i hua ake ai he pai ake ngā āhuatanga miihini me te pai ake o te mahi whānui i roto i ngā taiao uaua.
I tēnei wā, i whakatikatikaina anō ngā hanganga koranu o ngā maitai kore waikura super austenitic, me te whakanui ake i te taumata o te nikara me te molibdenum, me te whakaurunga mai o ētahi atu huānga pēnei i te parahi me te tungsten. Nā ēnei tāpiri i whakapai ake te ātete ki te waikura, inā koa i ngā taiao i pāngia ai te maitai e ngā katote hauota, ā, i whakarato i te ātete nui ake ki te pakaru o te waikura ahotea me te waikura kapiti.
Ngā tau 1990 me tua atu: Te Whakapai Tonu me te Tohungatanga
I te tekau tau atu i 1990, kua noho ngā maitai kore waikura tino austenitic hei rauemi nui i roto i te whānuitanga o ngā ahumahi. I haere tonu ngā kairangahau me ngā miihini ki te whakatikatika i ngā hanganga koranu kia tutuki ai ngā hiahia e tipu haere tonu ana o ngā ahumahi pēnei i te hinu me te hau moana, te mana karihi, me te tukatuka matū.
I whakawhanakehia ngā momo hou ake, pērā i te 254SMO, kei roto nei te 6% molybdenum, hei whakarato i te ātete pai ake ki te waikura me te whakaeke ā-rohe i roto i ngā taiao chloride. I piki haere te whakamahinga o ēnei rauemi i roto i ngā tipu tango tote wai moana, tae atu ki ngā tukatuka matū me ngā tono petrochemical.
Nā te rangahau me te whanaketanga tonu o ngā maitai kore waikura austenitic kua ārahi ki te whakamahinga i roto i ngā mara motuhake, tae atu ki te rererangi, te whakaputa hiko, me ngā taputapu ahumahi mahi teitei. Ka kitea ngā maitai kore waikura austenitic hou i roto i ngā momo whirihoranga, mai i ngā ngongo me ngā paipa kua whakarewahia ki ngā wāhanga hanganga uaua, nā te mea he pai te kaha ki te whakarewa, te hanga, me te ātete ki te waikura.
