Ko te tinei i te maitai he whakamahana i te maitai ki te pāmahana Ac3a (te maitai sub-eutectic) Ac1 rānei (te maitai over-eutectic) ki runga ake i te pāmahana, ka pupuri mō tētahi wā, kia tere ake te austenitization katoa, wāhanga rānei, kātahi ka tere ake te tere o te whakamatao o te whakamatao ki te Ms i raro (Ms tata rānei ki te isothermal) hei whakawhiti i te martensite ki te tukanga maimoatanga wera (bainite rānei). I te nuinga o te wā ka whakamahia hoki ngā koranu konumohe, ngā koranu parahi, ngā koranu titanium, te karāhe whakamaroke me ētahi atu rauemi hei āwhina i te otinga totoka "me te tukanga maimoatanga wera tere rānei e kiia nei ko te tinei".
Te kaupapa o te tineia:
(1) Whakapai ake i ngā āhuatanga ā-pūkaha o te konganuku hei rauemi, hei wāhanga rānei.
(2) whakapai ake i ngā āhuatanga rauemi, i ngā āhuatanga matū rānei o ētahi maitai motuhake
Ngā tikanga tinei: te tinei wai-kotahi te nuinga, te tinei wai-rua, te tinei whakarōpū, te tinei wera-whakakotahi, te tinei ā-rohe, me ētahi atu.
Ko te whakamahana i te whakarewa he mea whakamahana ki tētahi rauemi, ki tētahi wāhanga rānei, kia wera ki tētahi pāmahana motuhake, ā, i muri i te pupuri i tētahi wā, ka whakamatao i roto i tētahi tikanga maimoatanga wera. Ko te whakamahana he mahi i muri tonu i te whakamahana, ā, ko te tikanga he maimoatanga wera whakamutunga mō te wāhanga mahi, nō reira ko te tukanga tahi o te whakamahana me te whakamahana ka kiia ko te maimoatanga whakamutunga.
Ko te mahi a te whakamahana ko:
(1) whakapai ake i te pumau o te whakahaere, kia kore ai e puta te whakamahinga o te mahi i roto i te whakahaere o te whakawhiti, kia mau tonu ai te āhua me ngā āhuatanga o te mahi.
(2) Whakakorea ngā ahotea o roto hei whakapai ake i te mahi a te mea mahi, hei whakau hoki i te āhua o te mea mahi.
(3) te whakarerekē i ngā āhuatanga ā-pūkaha o te maitai kia tutuki ai ngā whakaritenga whakamahinga.
Ngā whakaritenga whakamahana: me whakamahana ngā whakamahinga rerekē o te rauemi mahi i ngā pāmahana rerekē kia tutuki ai ngā whakaritenga e whakamahia ana. (1) Ko ngā taputapu tapahi, ngā peera, ngā wāhanga whakaweto waro, ko ngā wāhanga mata kua whakamahanahia he mea whakamahana i te 250 ℃ i raro i te whakamahana pāmahana-iti, kāore e nui te rerekētanga o te pakeke i muri i te whakamahana pāmahana-iti, ka whakaitihia te ahotea o roto, ka paku whakapai ake te pakari. (2) Ko te puna i te 350 ~ 500 ℃ i raro i te whakamahana pāmahana reo, ka taea te whiwhi i te ngāwari teitei me te pakari e tika ana. (3) Ko ngā wāhanga maitai hanganga waro-reo he mea hanga ki te whakamahana pāmahana-teitei i te 500 ~ 600 ℃, kia whiwhi ai i te kaha me te pakari e tika ana.
Ko te whakaōrite he momo maimoatanga wera hei whakapai ake i te pakari o te maitai, ka whakamahanahia ngā wāhanga maitai ki te pāmahana Ac3 i runga ake i te 30 ~ 50 ℃, ā, i muri i te pupuri i te wā i waho o te hau-whakamatao. Ko te āhuatanga matua ko te tere o te whakamatao he tere ake i te hokinga mai me te iti iho i te tinei, ka taea e te whakaōrite te whakamatao tere ake i roto i te whakamahine i te kakano tioata o te maitai, ka taea e te takitahi tāpiri te whiwhi kaha pai, ā, ka taea te whakapai ake i te iti o te hurihuri (uara AKV), te whakaiti i te ia o te pakaru o te wāhanga, ētahi pereti maitai wera iti-konumohe, ngā whakarewa maitai iti-konumohe mā te whakaōrite, ka taea te purei i ngā āhuatanga miihini whānui o te rauemi hei whakapai ake, engari ka whakapai ake hoki i te mahi tapahi.
Ko te whakamahanatanga he whakamahana āta haere i te konganuku ki tētahi pāmahana, ka puritia mō tētahi wā roa, kātahi ka whakamahanahia ki tētahi tere e tika ana i roto i te rohe makariri o tētahi tukanga maimoatanga wera konganuku. Ka wehea te maimoatanga wera whakamahanatanga ki te whakamahanatanga katoa, te whakamahanatanga kāore i oti, me te whakamahanatanga whakaiti ahotea. Ka taea te whakamahi i ngā āhuatanga hangarau o ngā rauemi whakamahanatanga hei whakamātautau kume ki a Kinze, ka taea hoki te kite mā te whakamātautau pakeke. He maha ngā rauemi maitai e tukuna ana i roto i te āhua whakamahanatanga kua whakahokia mai, ka taea te whakamahi i te whakamātautau pakeke maitai ki te whakamātautau pakeke a Locke, te whakamātautau pakeke HRB, mō ngā pereti maitai angiangi, ngā rīpene maitai, me ngā ngongo maitai angiangi, ka taea te whakamahi i te whakamātautau pakeke mata a Locke, te pakeke HRT rauemi hanga.
Ko te kaupapa o te tinei me te whakamahana: 1. Hei whakapai ake i ngā hua, hei whakakore i te mārō o te tukanga whakarewa, hanga, hurihuri me te whakarewa i puta mai i ngā momo hapa whakahaere, me ngā ahotea toenga, hei ārai i te whakarerekētanga o te mea mahi, te ngatata. 2. Hei whakangawari i te mea mahi kia taea ai te tapahi. 3. Hei whakamahine i te witi, hei whakapai ake i te whakaritenga kia pai ake ai ngā āhuatanga miihini o te mea mahi. 4. Hei whakaoti i te maimoatanga wera whakamutunga (tinei, whakamahana) kia tutuki ai ngā paerewa whakaritenga.
Ko ngā tukanga whakamahana e whakamahia whānuitia ana ko:
(1) te whakamahana katoa. Whakamahia hei whakapai ake i te maitai waro o waenganui me raro mā te whakarewa, te hanga me te whakarewa i muri i te putanga mai o ngā āhuatanga miihini ngoikore o te kiko matotoru kua wera rawa.
(2) te whakamahana porowhita. Whakamahia hei whakaiti i te pakeketanga o te maitai taputapu me te maitai whāriki i muri i te hanga.
(3) te whakamahana isothermal. Whakamahia ana mō te whakamahi i ētahi nikara, te koranu hanganga maitai me te ihirangi chromium teitei.
(4) te whakamahana anō i te tioata. Whakamahia hei kawe i te waea whakarewa, te pepa i roto i te tukanga whakamaroke makariri, te huri matao (ka piki ake te pakeke, ka heke te kirihou).
(5) te whakawerawera i te kōhatu. Whakamahia hei hanga i te rino maka kei roto he maha o ngā tinana warowaihā hei rino maka ngāwari me te pai o te kirihou.
(6) te whakamahana horapa. Whakamahia hei hanga i te hanganga matū o ngā whakarewa koranu kia ōrite, hei whakapai ake i tōna mahi.
(7) te whakamahana i te ahotea. Whakamahia hei whakakore i te ahotea o roto o ngā whakarewanga maitai me ngā whakarewanga.
