Workpiece maitai hanganga i roto i te tukanga whakawera me te meangiti, e tika ana ki te inconsistencies auau tautauā o te paparanga mata me te wāhanga matua me te wa hanga he rerekētanga pāmahana, ka arahi i te reira ki te roha rōrahi me te contraction o te ahotea pāhiwihiwi e te ahotea wera.I roto i te ahotea waiariki e tika ana ki te pāmahana i raro i te mata i timata ki te wāhanga matua, he nui atu hoki te wehenga i te wehe i te wāhanga matua o te mānukanuka, ka te mutunga o te meangiti, no te mea e kore e taea e te wahi pokapū o te wehenga rōrahi mātao whakamutunga. ka waiho noa te wahanga o waenganui o te pehanga mata.I raro i te awe o te ahotea waiariki i te mutunga ko te pehanga mata o nga mea mahi me te ngakau o te Manatu Manatu.Ko tenei ahuatanga ko te tere whakamahana, te hanganga rawa me te maimoatanga wera me etahi atu mea.A, no te matao, te tere, te teitei te ihirangi waro me te hanganga koranu, tukanga tautauā pāhiwihiwi o te deformation kirihou i raro i te ahotea waiariki i hanga e te nui, te ahua whakamutunga o te ahotea toenga whiwhi reira.

I tetahi atu taha ko te rino i te wa o te maimoatanga wera na te huringa o te kiko ara ko austenite ki te martensite, me te pikinga o te rōrahi motuhake o te roha rōrahi o te taputapu mahi, he rereke nga waahanga o nga waahanga mahi, ka puta he koretake. o te rōrahi o te kiko tupu ahotea.Ko te mutunga ko te ahotea o te kiko o te mata, te ahotea o te ngakau, me te ahotea waiariki i te ritenga atu.Te ahotea i roto i te rahi o te mea mahi me te tere whakamahana o te tauwehe rohe huringa martensite, te hanga, te hanganga matū o te rauemi.
