He whānuitia te whakamahinga o ngā taputapu whakarara i roto i ngā taputapu tā, ngā taputapu rerekētanga motuka me ngā keti wai. Ka whakamahia hoki ēnei mō ngā waka tereina, ngā kaipuke, ngā tipu hiko, ngā tipu maitai, ngā tirotiro ara rerewē, me ētahi atu. Ki te whakaritea ki ngā taputapu whakarewa, he ohanga ngā taputapu whakarara, he roa te ora mahi, ā, he kaha. Nō reira, e mōhio ana koe ki ōna āhuatanga me te kaupapa tinei? Me titiro tātou ki tēnei me te ētita o te kaiwhakarato taputapu whakarara aorangi tino tika i raro nei!

1. Ngā Āhuatanga

1). He ātete matū kaha.

2). Te whakaiti i te haruru me te mimiti i te ru.

3). He roa te ora me te kaha kawe teitei.

4). Mama te taumaha, iti te utu.

5). Ngāwari ki te hanga, pai te whakahinuhinu.

2. Te kaupapa tinei

He nui te kawenga o te taputapu piko, he tino tika te whakapūmau, ā, he nui hoki ngā whakaritenga hangarau. Kāore e kore ka pāngia e te waku nui i te wā e mahi ana. He pai ake te tinei me te whakamahana i te taputapu piko hei whakapai ake i tōna pakeke, tōna ātete ki te kakahu me tōna roa o te mahi.

Ko te kaupapa o te tinei he huri i te austenite kāore i te tino matao ki te martensite, ki te bainite rānei, kia puta ai he hanganga martensite, bainite rānei, kātahi ka whakamahanatia ki ngā pāmahana rerekē hei whakanui ake i te kaha, te pakeke, me te ātete ki te kakahu o te maitai. Te mahi, te kaha me te pakari o te ngenge, me ētahi atu, kia tutuki ai ngā whakaritenga whakamahinga rerekē o ngā wāhanga me ngā taputapu miihini. Ka taea hoki te tinei kia tutuki ai te ātete ferromagnetic, te ātete ki te waikura me ētahi atu āhuatanga ā-tinana me te matū motuhake o ētahi maitai motuhake.
