Kupu Whakataki mo te kowiri wera o Austenithic

August 03, 2023
Ko te kowiri wera o Austetenitic he momo maitai-tuuru-wera e pa ana ki a Matrix he hanganga Austenitic. Kei roto i tenei momo maitai te nui ake o nga waahanga o Austenite penei i Nickel, Manganese, me te hauota. He pai te kaha o te pāmahana me te pūmautanga hanganga i runga 600, me te pai o te mahi. Ko te momo maitai tino whakamahia te nuinga o te wera-tuuru i te 600 ~ 1200 ℃.

Hanganga

I. Ko te nuinga o te waro te ihirangi kei runga ake i te 0.1%, tae atu ki te 0.4%. Me whakamahi te waro hei hanga i nga kaarai hei pupuri i te kaha waiariki.

II. Ko te nui o te kromium me te nickel tapiritia ko te nuinga o te 25%. Ka whakapai ake a chromium i te tipu thermochemistry me te kaha waiariki, a ka whakapumautia e Nickel ki te whiwhi kaupapa pumau.

III. Te taapiri i te Tungsten, Molybdenum, me etahi atu ka piki te pāmahana me te whakapiki ake i nga kaarai hei whakapai ake i te kaha wera.

Iv. Tāpirihia a Vandium, Titanium, konumohe, me etahi atu ki te hanga i tetahi waahanga tuarua, ki te whakapai ake i te kaha whakamaroke. Ko te rua o nga waahanga e rua nga momo: Ko nga motuka (penei i te VC) me nga pūhui takawaenga, penei i te ni, ko te li, a Al ranei, he pai ake te whakakaha.

Whakarōpūtanga

I. Cr-NI Series
Ko te raupapa tino whakamahia i roto i tenei momo maitai, me nga rereketanga o te kromium me te ihirangi nika kia tutuki ai nga hiahia o nga tohu pāmahana rereke. I te mea ka piki ake te ihirangi me te panui Nickel, ka piki te kaha o te riri me te kaha o te pāmahana me te kaha o te pāmahana. Tāpirihia te otinga totika e whakapakari ana i nga huānga (Tungsten, Molybdenum), ko te Vanbium, te nuobium, te viobium, titanium) me te ao e hiahiatia ana kia pai ake ai te kaha o te kowiri.

II. Raupapa cr-ni-n
Hei whakaora i te nickel me te whakapai ake i te kaha o te pāmahana o te maitai, ka tapiritia te hauota ki te kowiri.

III. Ko te raupapa CR-MN-NI-N-N-N me te raupapa CR-MN-N
Ko te taapiri i te Manganese me te hauota ki te kowhatu i te wa ano ka taea te whakaora i te hinu o te nickel, he nui te whakamahi i te miihini miihini miihini nui e kaha tu kaha ana te kaha o te pāmahana. I runga i tenei kaupapa, ko te taapiri i te Tungsten, Molybdenum, Vanadium, me te niobium ka kaha ake te whakapai ake i te kaha pāmahana-pāmahana me te whakamahi mo nga taumahatanga nui. 2cr20mn9ni2Ni2n me 3CRL8mnl2si2n he kaha pāmahana nui-pāmahana, me te pai o te ātete o te hāora. Ka taea te whakamahi hei taura whakairihia, nga waeine o roto, te whakawera i nga kowhatu o nga kaikopere, me etahi atu, ko te kowhatu CR-MN-NI te kaha teitei. Heoi, i runga i te taapiri o te mangannese i te rino, he kino te paanga o te whakawetanga o te pāmahana, kaore i te pai te whakaekenga o te hāora.

Iv. Seir-mn-al-al
Ko tenei momo maitai kaore i te kromium, me te nike ranei, me te hanga ano i te Manganese me te waro hei whakaoti i te raru o te konumohe nui-pāmahana. I roto i te whakaputa kowiri o te kowiri tira, he mea whakamahara-electro-slag e hiahiatia ana kia pai ai te kounga me te whakaputa.
