316l nga kaiwhakarato ngongo porowhita, Te Painga o nga Waahanga Alloying i runga i te Mahia o Austenitic Stainless Steel

E hia nga wa i pa mai nga raruraru whakangao i te wa i whakauruhia ai nga porowhita hou, rewa ranei ki roto i te mahi?Ko enei raruraru he pakaru, he kapiti, he pupuhi, he ngoikore te urunga o te weld, he ngoikore te mata hiko, me etahi atu.Ko nga whakamatautau pakeke, nga whakamatautau tensile, me nga waahanga whiti whakarewa, me te arotake i nga purongo whakamatautau wheketere he tikanga noa mo te whakatau i te puna o te raru.I etahi wa ka kitea te putake o te raru, engari ko te nuinga o nga wa kaore e kitea he mea rereke.I roto i enei take, ko te raruraru kei roto i te hanganga o te maitai, ahakoa ko te konumohe kei roto i te waahanga hanganga kua tohua mo te maitai.

I roto i tenei tuhinga, ka whakawhāitihia a maatau korero ki nga tira kowiri tira austenitic, ahakoa ko te nuinga o nga korero e pa ana ki etahi atu momo.He maha nga mea raru kaore i te mana, me tohu ki runga i te whakaritenga a te kaihoko me te ota hoko.Kaua e whakaaro ko te koranu e hokona ana e koe mai i te awhe toharite o ia mea.Mai i te tau 1988, he kaupapa e kiia ana ko te "parapara mira" e whakamahi ana i te iti rawa o nga huānga whakakotahi hei aukati i te wera wera me te pakaru o te matao.
Ko te Hoahoa Tohu Ko nga tira kowiri tira Austenitic i hangaia hei whakarato i te parenga waikura i roto i te maha o nga taiao, te aukati ki te hauwai me te embrittlement i te 885ºF (475ºC), te kaha pai, te ngawari me te iti o te pakeke.Ko te rino he rino me te 12% chromium te iti rawa.Koinei te mea ka taea e te kowiri tira te atete ki te waikura ka taea te hanga i tetahi kiriata hāngū.Ko te kowiri tira kei roto i nga ahuatanga whakarewa e toru i runga i te hanganga me te maimoatanga wera: ferritic, martensitic me austenitic.Ko enei ingoa e pa ana ki te hanga karaihe: ko te ferrite he kohanga-a-tinana, ko te austenite ko te mata-pokapū-a-kanohi, ko te martensite he punaha tetragonal miro, ara, ko te hangahanga putorino i te kanohi ka huri ki te tinana.
Ko te rino parakore he ahua tapatoru-a-tinana me te noho mai i te kore tino ki tona ira whakarewa.Ina taapirihia etahi waahanga, ka hangaia he "nga mowhiti gamma" he austenite ranei.Ko enei huānga he waro, chromium, nickel, manganese, tungsten, molybdenum, silicon, vanadium me te silicon.I roto i enei huānga, ko te nickel, manganese, chromium me te waro ka taea te whakawhanui i te mowhiti gamma ki te tawhiti rawa atu.Ko te whakakotahitanga o te nickel me te chromium e hanga ana i nga tira kowiri tira austenitic ki te anga ki te kubiko mai i te kore tino ki te ira whakarewa.Koinei te mowhiti gamma e wehewehe ana i nga koranu ferritic mai i nga martensitic.Ko te ihirangi chromium o te martensitic kowiri tira he tino whaiti, 14-18%, me te waro, no te mea ka wera i roto i tenei awhe ka taea te hanga austenite parakore, kia taea te whiwhi martensite ma te tinei.Ko nga koranu Ferritic he ihirangi kei raro iho i te 14% neke atu ranei i te 18%.Ko te whakarereke i nga huānga whakakotahi ka taea te whakarereke i te awhe.Ko te huarahi tino noa ko te pupuri i to warowaiha kia iti.
Ko nga tira austenitic tino noa i runga i te hanganga 18-8, 18% Cr 8% Ni.Mena ka nui ake te nickel i roto i te rino i te 8%, he austenitic, mena he iti iho te ihirangi nickel, he tira taarua, ara, austenitic me nga moutere ferrite.I te 5% nickel, ko te hanganga he 50% austenitic, 50% ferritic, kei raro iho i te 3% ka tino ferritic.No reira, ko te 8% nickel te turanga mo nga tira kowiri tira austenitic iti rawa atu.
Ina whakauruhia nga huānga whakakotahi ki te rino, ka taea e ratou te noho ki roto i te karaihe matua.E mohiotia ana enei ko te koranu whakakapi, ka noho tonu te koranu ki te wahanga kotahi.Ko etahi atu huānga he iti rawa kia uru ki waenga i nga ngota, e kiia ana ko nga huānga interstitial, ka noho tonu te koranu hei wahanga kotahi.Ko etahi atu huānga ka whakakotahi ki te hanga i o raatau ake tioata ahurei me te hanga i nga waahanga motuhake.Ko etahi ano he poke i roto i te koranu, e kiia nei he whakauru.
