ngongo kowiri tiramaimoatanga wera kaupapa matua ko te ki te huri i te putorino o roto hanganga matrix whakarewa, te whakapai ake i te pakeke o te putorino kowiri tira, engari no te mea e kore e tino huri i te morphology putorino, a na reira e kore e taea te whakapai ake i te kaha me te uaua o te ngongo kowiri tira.Kowiri tira ngongo tineia pāmahana kia tīpakohia i roto i te pāmahana tino nui 30-70℃, na te ngoikore o te kawe wera o te rino, ko te waa pupuri he tata ki te rua te piki ake i te maitai.

I taua wa, ki te whakaiti i te ahotea tineia, i mua i te tinei kia i roto i te rangi i mua i te meangiti, te tikanga whakamahi kaha te reo tinei hinu ki te karo tinei hangai e taea hoki te tango i te hinu moata (matao ki te 200-300℃) huarahi whakamahana hau.I muri tinei ngongo kowiri tira, ka taea te hanga martensite matrix hei troostite ranei i muri i te tempering tempered ki sorbite, i te tinei, tukanga tempering me te putorino kowiri tira atu putorino he kore rerekētanga faufaa i muri tinei kia riri kowiri tira.Ko te rino kowiri ka taea ano te whakamaarama i te waiariki tiini te reo wera, te hinu wera ranei, hei tauira, i te 830-870℃, ka whakamahana ka tineia 280-350℃pākawa hauwaro.Ko te paipa paipa tinei, ko te tiini waiariki ranei, he mea whakamiharo te whakapai ake i nga taonga miihini i te rino maka hina.

I roto i te tikanga ki te whakapai ake i te mata pakeke, me te mau ātete o te putorino kowiri tira, ka taea e te mura mata whakapakeke, tiketike-auau mata whakapakeke me te maimoatanga wera matū, i reira he auau tiketike he auau takawaenga mata pakeke te nuinga o tono.High, reo auau mata pakeke ki te wa whakawera he poto, iti hāora me te decarbonization, he iti deformation, me te ngāwari mahi, te pāmahana whakawera ko te tikanga 850-950℃, putorino kowiri tira na te kino o te kawe i te waiariki, me te iti o te waahi whakarewa, kaore i te tere rawa te tere o te whakamahana, ki te kore ka pakaru, ka rewa ranei.High, reo auau tukatuka ngongo kowiri tira e kore anake e taea te whakapai ake i te pakeke mata, me te kakahu ātete, engari ano hoki tino whakapai ake i te kaha rohirohi, whakanui i te ora ratonga, te tahi atu, Miihini Utauta hiko mata whakapā hiko o te whakawera he tauira angamaheni o te kowiri tira. te whakapakeke o te mata ngongo.I roto i te tikanga ki te tiki i te whakahaere matrix pai ki te whakarite i te ngongo kowiri tira roto mārō mata me ngā āhuatanga pūkaha e taea te whiwhi i muri i te pakeke tiketike, maimoatanga wera mata i mua i te pai i mua i te tikanga tineia me te tempering maimoatanga.
