Ko te whakapouri pango, ehara i te mea he mahi whakaenee noa, engari ko te tukanga me te whakaenee tata.Paipa pango maitaihe waikura pango te kiri!

Te whakawhanaunga: ka whakawerahia te koranu whakarewa ki te pāmahana e tika ana kia mau tonu te waa, katahi ka puhoi te whakamaarama whakamahana wera.Ko te rino kua oti te whakarite hypoeutectoid ferrite pearlite;Ko te maitai eutectoid, ko te rino eutectoid ranei he pearlite maramara.I roto i te poto whakahaere annealing he tata ki te whakahaere kāwanatanga taurite.

Te kaupapa o te whakaene

①whakaiti i te pakeke o te maitai, pai ake ductility, i roto i te tikanga ki te whakahaere tapahi me te tukatuka deformation matao.

②te whakamahine witi, te whakakore i te makanga, te hangahanga, te koha o te whakapiri na te whakahaere, te whakahaere me te hanganga o te maitai rite, te maitai hei whakapai ake i te mahi, mo te maimoatanga wera o muri mai mo te whakarite kiko.

③whakakore i te ahotea o roto i roto i te maitai ki te aukati deformation me te kapiti.
