Ko te whakamahana he maimoatanga wera mo te whakamahana i te rino mate ki te Ac3 (te maitai hypo-eutectoid) ranei te Accm (te maitai eutectoid me te hyper-eutectoid) i runga ake i te 30~50°C, te whiwhi austenite, te whakamahana i te hau, me te maimoatanga wera o te hanganga rite kei roto. mahi pearlite.
Ko te kaupapa o te whakarite: ko te whakatikatika i te maitai o te mate ko te whakapai ake i te miihini, te whakakore i nga ngoikoretanga mahi wera, te whakakore i te carbide whatunga i roto i te maitai mate hypereutectoid, te whakarite mo te hanganga annealing spheroidizing, me te whakapai ake i nga taonga miihini o te mate.
He tikanga whakamahana te whakamahana i te wera ka whakamahana te maitai mate ki te mahana i runga ake ranei i raro iho i te ira tino nui Ac1, katahi ka ata whakamatao ki te pāmahana oumu i muri i te whakamahana wera kia whiwhi ai i te hanganga taurite tata.
Ko te kaupapa o te annealing: Ko te kaupapa matua ko te whakakotahi i te hanganga matū me te hanganga o te rino mate, te whakamahine i nga karepe, te whakatika i te pakeke, te whakakore i te ahotea me te mahi whakapakeke, te whakapai ake i te hanga me te machinability o te maitai, me te whakarite i te hanganga mo te tinei. .
