He aha nga tino mate o te wai hei whakamahana whakamahana mo te whakamatao?

1) i roto i te mapi huringa waiariki austenite o te waahi angamaheni, ara, tata ki te 500-600 ℃, te wai i roto i te atamira kiriata koromamao, kaore i te tere te tere o te whakamahana, he maha nga wa ka pahekeheke.te patupatute whakamahana me te iti o te tere whakamahana me te hanganga o te "waahi ngohengohe". I roto i te punaha panoni martensite, ara, mo te 300-100 ℃, kei roto te wai i te wa e koropupu ana, he tere rawa te tere o te whakamatao, he ngawari ki te hanga i te tere o te huringa martensite he tere rawa te whakaputa i te taumahatanga o roto, ka arahi ki te te whakapouritanga o te hanga me te pakaru.
2) He nui te awe o te paanga o te wai ki runga i te kaha whakamahana, na reira ka aro nui ki te huringa o te pāmahana ambient. I te pikinga o te pāmahana wai, ka tino heke te kaha whakamahana, ka neke te awhe pāmahana o te reiti whakamahana morahi ki te pāmahana iti. Ka nui ake te mahana o te wai ki te 30 ℃, ka tino heke te reiti whakamahana i roto i te awhe o te 500-600 ℃, he maha nga wa e pa ana ki te whakapakeke o te wai.whawhati, engari he iti te paanga ki te reiti whakamatao i te awhe o te panoni martensite. Ka piki ake te pāmahana wai ki te 60 ℃, ka heke te reiti whakamahana ma te 50%.

3) ka nui ake te hau (penei i te wai hou), te wai ranei i konatunatua ki nga poke korekore, penei i te hinu, te hopi, te paru, me etahi atu, ka tino whakaitihia tona kaha whakamahana, na reira me aro nui te whakamahi me te whakahaere. ki.
E ai ki nga ahuatanga whakamahana o te wai, ko te tikanga ka taea te whakamahi i te wai H ki te whakamahana o te waro maitaiwhawhatihe iti te rahi o te waahanga me te ahua ngawari. Ko te tinei, me mahara ano: kia mau tonu te pāmahana wai ki raro i te 40 ℃, te pai rawa atu i waenga i te 15 ki te 30 ℃, me te pupuri i te wai, te rere wai ranei, ki te whakangaro i tete patupatukiriuhi mamaoa mata, ka taea hoki te whakamahi piu mahi i te wa e tineia ana (kia neke ake ranei te mea mahi ki runga, ki raro) tikanga ki te whakakore i te kiriuhi mamaoa, te whakanui ake i te reiti whakamahana i waenga i te 500-650 ℃, nga tikanga whakamahana, karohia ki te whakaputa i te waahi ngohengohe.
