Teiteipaipa koranuwhakakaha deformation ko te whakamahi o tikanga whakapakari maitai.E mohiotia ana ano he whakapakeke, he whakamaroke ranei.Ko te kaha o te rauemi i te tonotono (te katoa ranei) te kaha ki te aukati i te rerekee (te ahotea rere ranei).Ko te pakeke ko te kaha o te rauemi ki te aukati i te rerekee o te kirihou o te rohe (ahakoa te pakeke, te pakeke Vickers, te pakeke o Rockwell me te Brinell ranei).He rite nga hononga e rua i roto i te maha o nga keehi.Ko te kaha o te rauemi, ko te nui ake o te parenga whakakino kirihou, ka nui ake te uara pakeke.I tua atu, ko te teitei ake o te pakeke o te rauemi, ko te rauemi na te piki haere o te pakaruhanga, kaore i te tino kitea tona kaha i roto i taua uara tohu kaha kaore i te teitei.

No te roa i raro ki te maimoatanga wera, me te whakamahi o ngā rauemi i roto i te pāmahana pai i raro i te recrystallization pāmahana o te ngongo koranu teitei-pēhanga maitai putorino rauemi, maha whakamahi matao (deformation matao) tikanga ki te hanga i te reira i roto i deformation whakakaha ki te whakapai ake i te kaha.Ko te kupu, deformation whakapakari i te mauri recrystallization pāmahana o te rauemi te deformation matao e whai ake nei, ki te tohu o te deformation (te riaka) kua nui haere, hua i roto i te kiato tiketike o dislocations (kohakore tioata), te teitei te kiato dislocation i roto i te karaihe, te nui te tohu o te whakarei ake, te teitei te ahotea rere.I muri i te rere deformation kia kaua e rite te ahotea o ngongo maitai i mua i te rere ahotea deformation whakapakari deformation me te ahotea rere āpitihanga.Te whakamahi o te whakakaha deformation ki te whakatutuki i te kaha teitei hua maitai, he angamaheni tiketike-wao maitai waea matao-unu me te iti-waro iti-kokohanga matarua waea maitai matao-unu.

Ka piki ake te tohu o te deformation, ka piki ake te kaha o te rauemi me te pakeke, engari ko te ngawari me te uaua kei te heke haere tonu, ka nui ake te pakaru, me kaha ki te whakapai ake i te ahuatanga.I whakaawehia a roto i roto i te huringa o te wahanga martensitic i roto i te wahanga whakamatao mo te whakapakeke, tona mauri tinana, no te whakakaha deformation hoki, engari i tenei wa ehara i te huringa o waho, engari mai i te huringa o te martensitic o te moka kiato karaehe nui te kutikuti na te pohehe. .
