He mea tika ki te whakahaere maimoatanga wera i murite patupatuno te mea ko tana kaupapa ko te whakakore i te ahotea o roto i muri i te hangahanga.Whakaritea te pakeke o te hanga, whakapai ake i te mahi tapahi;Ko nga kakano maru i roto i te mahi hangai he para me te rite ki te whakarite i te microstructure o nga waahanga mo te maimoatanga wera.

1. Te whakamahana i te pāmahana teitei: whakaitihia te pakeke, whakaiti, whakakore ranei i te ahotea i puta i te wa e whakamahana ana te whakamahana, te whakapai ake i te kirihou me te uaua.E tika ana mo te koranu rino me te pakeke teitei i muri i te whakarite.

2. Whakaotia te annealing: whakakore i te hanganga taratara me te koretake i puta mai i te mahi hangai, te whakamahine i te witi, te whakakore i te toenga o te ahotea o te hanga, te whakaiti i te pakeke, te whakapai ake i te miihini, me te whakarite i te whakahaere mo te maimoatanga wera o nga waahanga.Ko te tikanga he pai mo te rino hypoeutectoid te whakakii.

3. Whakawhanaunga Isothermal: whiwhi hanga riterite ake i te oti annealing, te whakakore pai i te ahotea, whakaiti i te pakeke.I roto i nga whao nui nui, ka taea hoki te whakamahi ki te whakamarara i te hauwai me te aukati i te hanga o nga wahi ma.Ka whakatauritea ki te whakakii oti, ka taea te whakapoto i te wa whakangao me te whakapai ake i te pai o te whakaputa.

4. Whakariterite: ka taea te whiwhi peara pai hei whakamahine i te whakahaere;Whakapai akewhakangaote kaha me te pakari, te whakaiti i te ahotea o roto, te whakapai ake i te mahi tapahi;Mo te maitai eutectoid.Ka taea te whakakore i nga carbide mata.

5 spheroidization annealing: ki te whiwhi cementite porowhita me te hanganga ferrite, e kore anake whakaiti i te pakeke, a i roto i te tukanga tapahi he ngāwari ki te tiki mata tukatuka maeneene, i roto i te tinei muri e kore he ngāwari ki te whakaputa kapiti deformation.He pai mo te maitai waro teitei me te waro koranu koranu teitei.
