Ko ngā maitai kowiri tira takirua, e mōhiotia ana mō te whakakotahitanga o ngā āhuatanga austenitic me te ferritic, he tohu tēnei mō te whanaketanga o te mahi whakarewa, e tuku ana i te whakakotahitanga o ngā painga me te whakaiti i ngā ngoikoretanga ā-roto, i ētahi wā i te utu whakataetae.
Te Mārama ki te Kowiri tira takirua:
Ko te mea nui o te maitai kore waikura takirua ko tōna hanganga iti-wāhanga-rua, he ranunga taurite o te austenite me te ferrite, e whakaputa ana i te hononga o ngā āhuatanga pai me te whakaiti i ngā ngoikoretanga. Ahakoa e whakawhirinaki ana ki te taumata motuhake, ko te hanganga whakarewa he waro, te manganese, te silicon, te chromium, te nickel, te phosphorus, me te whanariki, me ngā tāpiringa kōwhiringa pēnei i te molybdenum, te hauota, me te parahi e whakapai ake ana i ngā āhuatanga o te rauemi.
Te Horopaki Hītori o te Kowiri tira takirua:
Ko te tīmatanga o ngā koranu kowiri tira takirua i ahu mai i ngā whakaaroaro ariā i te tekau tau atu i 1920, ā, i mutu ki ngā mahi whakaputa i ngā tekau tau atu i 1930. I te tīmatanga, i herea ki te whakaputa whakarewa me ngā tono motuhake nā te nui o te ihirangi waro, nā te whanaketanga o te tango waro i te mutunga o te tekau tau atu i 1960 i tohu he wā hou, e whakahaere ana i te hanganga o ngā koranu waro-iti me te ihirangi chromium me te nickel kua arotauhia, ā, nā reira i whakatikatika i te taurite i waenga i te ferrite me te austenite. Ko te tohu o tēnei ara whanaketanga ko te Duplex 2205, he koranu paionia mai i waenganui o te tekau tau atu i 1970 e mau tonu ana te hiranga nā tōna ātete ki te waikura ki ngā taumata austenitic tikanga.
Ngā Painga o te Kowiri tira takirua:
Ahakoa he wāhanga iti noa iho o te mākete maitai kore waikura, he maha ngā painga o ngā koranu takirua ki ērā atu koranu austenitic me ferritic tuku iho. Ko te mea nui i roto i ēnei painga ko te kaha ake, te pakari ake, me te ngāwari, me te ātete ki te waikura e puta ake ana hei āhuatanga matua, e whakataetae ana, ki te kore e eke ki runga ake, i ngā momo austenitic. Heoi anō, ko te whai huatanga o te utu o te maitai takirua, nā te whakamahinga tupato o ngā huānga koranu, ka waiho hei whiringa pai puta noa i ngā tono rerekē.
Ngā tono o te maitai kore waikura takirua:
He rongonui te maha o ngā mahi a te maitai kore waikura takirua puta noa i ngā ahumahi me ngā mara, nā tōna ātete pai ki te waikura, tōna kaha ake, me ōna āhuatanga utu iti. Ko te nuinga o ngā mahi ki tai me te takutai moana, tae atu ki te keri hinu, te tango tote, me te maimoatanga wai, ko rātou ngā tino painga o te kaha o te maitai takirua. Waihoki, ka horapa tōna whai huatanga ki te tukatuka matū, ki ngā tono moana, ki ngā taputapu whakahaere parahanga, me ngā mahi hanga, e whakaatu ana i tōna noho whānui i roto i ngā whenua ahumahi o nāianei.
