Ko te tukanga o te whakamahana, te pupuri, me te whakamatao i tetahi konganuku i roto i te ahua totoka hei whakapai ake, hei whakarereke ranei i ona ahuatanga me te hanganga moroiti ka kiia ko te maimoatanga wera.E ai ki nga kaupapa rereke o te maimoatanga wera, he rereke nga tikanga maimoatanga wera, ka taea te wehewehe ki nga momo e whai ake nei:

(1)Te whakaene: I roto i te oumu whakamahana wera, ka whakawerahia te whakarewa i tetahi tere whakawera ki te 300-500 ℃ i runga ake i te pāmahana tino nui, a ka huri tona hanganga moroiti ki te hurihanga wahanga, ki te huringa wahanga wahanga ranei.Hei tauira, ka whakawerahia te maitai ki tenei pāmahana, ka huri te pearlite hei austenite.Katahi ka whakamahana mo tetahi wa, ka ata whakamataohia (te tikanga me te whakamatao oumu) tae noa ki te tukunga i te pāmahana rūma.Ko tenei tukanga katoa e kiia ana ko te maimoatanga annealing.Ko te kaupapa o te annealing ko te tango i te ahotea o roto i te wa e mahi wera ana, te whakakotahi i te microstructure o te konganuku (ki te whiwhi i te hanganga ahua taurite), te whakapai ake i nga taonga miihini (penei i te whakaheke i te pakeke, te whakanui i te kirihou, te uaua, me te kaha), me te whakapai ake i te tapahi. mahi.I runga ano i te tikanga whakahiato, ka taea te wehea ki nga momo tikanga whakahiato penei i te whakamaaramatanga noa, te taapiri rua, te whakamaaramatanga o te whakamaarama, te whakamaarama isothermal, te whakahiato spheroidizing, te whakahiatotanga, te whakahiato kanapa, te whakakii oti, te whakakii kore, me era atu.

(2)Whakariterite: I roto i te oumu whakamahana wera, ka whakawerahia te whakarewa i tetahi tere whakawera ki te 200-600 ℃ i runga ake i te pāmahana tino nui, kia huri katoa te microstructure ki te austenite kākahu (hei tauira, i tenei pāmahana, ka tino huri te ferrite. ki austenite i roto i te maitai, te cimentite tuarua ranei kua tino rewa i roto i te austenite), ka pupuri mo te wa roa, Katahi ka tuu ki te rangi mo te whakamatao taiao (tae atu ki te pupuhi hauhautanga, te tapae mo te whakamahana taiao, nga waahanga takitahi ranei mo te taiao. te whakamatao i roto i te hau marino), a ko te tikanga katoa ka kiia ko te whakarite.Ko te Normalizing he ahua motuhake o te whakaene, na te mea he tere ake te whakamahana i te whakamaarama, ka taea te whiwhi i nga karepe pai me te hanganga moroiti rite, te whakapai ake i te kaha me te pakeke o te whakarewa, me te pai o nga taonga miihini.

(3) tineia: I roto i te oumu maimoatanga wera, ka whakawerahia te whakarewa i tetahi tere whakawera ki te 300-500 ℃ i runga ake i te pāmahana tino nui, kia huri katoa te microstructure ki te austenite kakahu.I muri i te pupuri mo te wa roa, ka tere te whakamahana (he wai, te hinu, te wai tote, te wai kawakore, me etahi atu) ki te whiwhi i te hanganga martensitic, ka taea te whakapai ake i te kaha, te pakeke, me te kakahu o te whakarewa. .Ko te whakamahana tere i te wa e tineia ana ka arahi ki te huringa hanganga koi e puta ai te ahotea o roto, ka piki ake te pakaruhanga.Na reira, he mea tika ki te whakahaere i te whakamaarama, i te maimoatanga tawhito ranei i roto i te waa ki te whiwhi i te kaha nui me nga taonga pakari.Ko te tikanga, he iti noa te whakamahi i te maimoatanga tiini anake.I runga i te kaupapa me te kaupapa o te maimoatanga tiini, ka taea te wehewehea te maimoatanga tiini ki nga momo momo momo mahi penei i te tiini noa, te tiihi oti, te tiihi kore, te tiihi isothermal, te tiini tohu, te tiihi kanapa, te tiihi teitei, etc.

(4) Te tinei o te mata: He tikanga motuhake tenei mo te whakamaarama whakamahana e whakamahi ana i nga momo momo whakamahana penei i te whakamahana o te mura, te whakamahana whakawera teitei, te whakamahana hiko hiko, te whakamahana whakapiri hiko, te whakamahana electrolyte, me etahi atu kia tere te wera o te mata o te konganuku kei runga ake i te pāmahana tino nui, ka tere whakamatao i mua i te urunga o te wera ki roto whakarewa (arā, te maimoatanga tinei)
