Nga take o te kakano rerystallization paipa maitai

I roto i te deformation wera, te witi, poke me kohakore i roto i te wāhanga tuarua me te momo o te whakarewa i roto i te toronga mōrahi haere te ahunga deformation matua elongated, attenuated, me te kaha o te hanganga o te ahunga muka he teitei ake i te kaha o te rauemi kei tera atu huarahi (Mehemea ka tino kitea te awe o te kumete), he rereke nga tohu o te anisotropy.

I tua atu, ka taea te deformed waiariki deformed wā kotahi paraharaha kakano me te kakano recrystallization, hanga hoki ratou te rauemi puta directivity me te ōritetanga.16Mn maitai me te konumohe whakautu i roto i te tukanga deformation wera.Konumohe me ona koranu i roto i te tukanga deformation wera o te pūngao hapa tāpae he nui, ka taea e te tūringiringi whaiaro iti.I nga wera nui, ka paheke te wehenga me te piki ngawari.Na reira, ko te urupare hihiri ko ratou anake te umanga i roto i te ngawari o te wera i te wa o te huringa.I muri i te deformation teitei pāmahana o te koranu konumohe i kitea tonu, i roto i te whakahaere e taea te kite i te maha nui o whakautu subgrain.Ko te urupare hihiri o te whakahaere ki te pupuri i te putorino hiato kakahu-atete kua pai te whakamahi ki te whakanui ake i te kaha o te 6063 koranu hanga kōtaha extruded.Konumohe me te konumohe koranu ngongo i roto i te matao, te tukatuka waiariki tāpiapia, ngāwari ki te piri ki te taputapu ki te hanga i ngā koha o mata, kia pai whakahinuhinu te hangarau tukatuka raw.I tenei wa, ko te whakaoti o te mata me te pokepokea o te mata e hiahiatia ana kia nui te utu.I tua atu ki te konumohe, kia whakahaere i te tere extrusion, te tahi atu alloys i to ratou ake awhe tere extrusion tika.Me whiriwhiri te reira extruder tere te whakarite, i tino whakahaere i te pāmahana o te tukanga extrusion, tere, karo tauira kakahu o Buddhist monaki.

Ko te maitai 40Cr me te maha o nga koranu konumohe i te pāmahana teitei, te pehanga teitei, nga tikanga korehau teitei he ngawari te hono tahi.Na ki te hanga ngongo ki te hanga tikanga pai.Ko te pokepokea o te waka rererangi me te arero-ahua te tangohanga mate ko te whakamahi i te ahuatanga ki te whakaputa paipa.Tenei e kore anake whakawhānui i te momo putorino me te whakamahi, a ka taea te whakamahi i te extruder pae noa, me te ingot totoka ki te pēhanga ōhanga putorino ripeka-wāhanga he tino uaua, me te maiengi putorino.
