Ko te tineia me te whakamahana, he tukanga maimoatanga wera e mahia ana i te wāhanga whakaotinga whakamutunga o ngā wahi, ka whakatau i ngā āhuatanga miihini teitei.
Tukunga JINDALAIKo ngā rino mahi matao, huri wera me te whakarewa mō te tinei me te whakamahana e whakarato ana i ngā otinga tuku ritenga i runga i ngā whakaritenga me ētahi atu whakaritenga motuhake kia tutuki ai ngā hiahia o ia kiritaki e pā ana ki ngā māka me ngā kōtaha. Ko tā mātou kamupene, me tana 10pekangā tarii rotoHainame te kaha tohatoha ā-tau e 200,000 Tana, te hoa tino pai hei whakawhānui i tō pakihi.
He aha te maitai whakamātao me te rino whakamahana?
Kei roto i ngā maitai katoa he waro, ā, ka uaua ake. Mēnā he nui rawa te waro, ka ngoikore te āhua o te maitai. Ka whakamahia ngā tukanga tinei me te whakamahana hei whakanui ake i ngā āhuatanga ā-pūkaha o te maitai waro, me te kore e tāpiri atu i te waro.
Ko te ōwehenga o te maitai waro-nui he 0.60 ki te 1.00% te nui o te waro, ki te whakaritea ki te ōwehenga 0.05 ki te 0.25% o te maitai ngawari. Ina tukuna te maitai waro-nui ki roto i te tukanga tinei me te whakamahana, ka nui ake te ātete ki te kakahu me te pakari o ōna āhuatanga hangarau.
Mā tēnei tukanga ka tere te whakamatao (tinei) te whakarewa, ka whakamahana anō hoki mā te whakamatao puhoi (whakamahana). Ko ngā tukanga tinei me te whakamahana te kawenga mō te tāpiri i te kaha me te pakari ki te maitai.
Ngā taahiraa tukanga For Qte whakamātau me teTte whakamātao
Hei awe i te pakeke me te kaha o te maitai, kua whakawhanakehia he maimoatanga wera motuhake, e kiia nei ko te tinei me te whakamahana. Ka taea te wehewehe i te tinei me te whakamahana kia toru ngā taahiraa matua:
Ate whakawera → te whakamahana ki runga ake i te rārangi GSK ki roto i te rohe austenite
Quenching → te whakamatao tere i raro i te huringa γγ-αα
Tte whakamahana anō ki ngā pāmahana reo me te whakamatao puhoi

E ai ki te kōrero i mua ake nei, he maha ngā painga o te maitai kua tineihia me te maitai kua whakamaroketia, tae atu ki:
Te Kaha Whakanuia
Te Whakanuia o te Pakari
Te Iti o te Whakapohehe
Ngā Āhuatanga Ā-tinana e Matapaetia ana
Ngā tono o te maitai kua tineia, kua whakapakeketia hoki
Ngā Utauta Mīhini me te Tapahi
Te Hanga Piriti
Ngā Hanganga Teitei
Ngā Taputapu Hanga Taumaha
Ngā Tāke Rokiroki Matū
Ngā Raina Taraka Para
Mīhini Ahumahi
Ngā Waka Kaha Ake, Mama Ake
Ngā Taputapu Ngāherehere
Ko te āhuatanga motuhake o ēnei momo ko tō rātou ngāwari ki te hanga i roto i te āhua huri-wera me tō rātou kaha teitei i muri i te maimoatanga wera. Ka tutukihia ngā āhuatanga kaha i tua atu i te waro me te konupora, inā koa nā te iti o te ōwehenga o te boron.
