Kakano ia Pūhui Mārō

E whakamahia ngā hanganga Metal i roto i te katoa ahumahi, engari, kāore, e taea e kore hua katoa e maka i roto i te oumu ranei i roto i te puka. E kore te wahi rite-hanga he watea ki te hono rivets takahuri ranei tonu. Hoki ngā take pēnei i, me te hiahia fehokotaki'anga (hononga fehokotaki'anga ranei) - te tukanga o ngā hua whakarewa hononga haumaru, e hāngai ana nei i runga i te pūhui interatomic. Whakarōpū me ngā momo o te kakano ia he rota, ko te matua - e toru o ratou, e taea te taratahi i roto i te rōpū nui motuhake. Tenei tikanga aunoa, waiariki, me ngātahi - thermomechanical. wāhanga hononga Mechanical rerekē fehokotaki'anga i raro i te pēhanga ranei pahūtanga, sonication, te waku. fehokotaki'anga Thermal - he tikanga wē, he pewa hiko, taiaho, irahiko kurupae me te rite.

āhuatanga āhuatanga o te fehokotaki'anga me ngāwhā fehokotaki'anga

Tata nga momo o fehokotaki'anga wera tā te whakamahi o te waea motuhake. I roto i te fehokotaki'anga pewa, ngā waea fehokotaki'anga te i roto i te kawehiko, i roto i te tahi atu wā katoa, he reira rite te wāhanga motuhake tukua ki te wāhi fehokotaki'anga te waea. Ka taea e whai ia he diameter rerekē me te rauemi - ia o te whakarewa Weld hiahia hoki ona ake waea ki ngā whakaritenga motuhake e makona nga whakaritenga o te hononga iho paiherea.

Ka taea te kawea Tapia fakafoki mai o ngā wāhanga tawhito ranei i roto i te mahi i roto i na roto i te fehokotaki'anga - tono ki te kōpeke whenua ranei atu o te kahu hou o te whakarewa. Ko te tikanga e whakamahia ana mō te papa o te whakarewa ano, engari e kore te mea e tika ana tenei huru. I te tahi taime, rawa ki te tirohanga ki te whakapai ake i te āhuatanga hangarau me ngā āhuatanga mahi mō te waea fehokotaki'anga tango tetahi ki te hanganga matū rerekē. Hei tauira, he niho peere excavator hanga o te whakarewa ake roa ki te ihirangi waro tiketike.

pūhui kakano ia: tohu i te waea mō te fehokotaki'anga

Tohu hanga ngāwari reira ki te whakatau he aha kia whakamahia ahua o te waea mo te ngā momo o te fehokotaki'anga mahi. Ko te mati tuatahi tohu te diameter me Kua tohua te tohu reta ahua o te whakarewa (huānga koranu). Ko te reta "St." tikanga "waea fehokotaki'anga", me te pa ratou whika - te hautanga waro o 0.01 protsenta.Iduschaya i tau reta - te ōrau o dopant i te waea. Alloying huānga e tohua: A - hauota, B - NB, V - W, T - Konupora, D - Konukura K - konukurahina, M - molybdenum, H - nika, ūkuikui N- C - Si, T - Titanium, F - vanadium, X - Konqueror, Yu - konumohe. Na, ahua o te ōrau o tenei huānga i roto i te waea e tu ana. Heoi, ka he iti iho i te kotahi te ōrau, e kore e hoatu i te mea whakaahua. Hei tauira, fehokotaki'anga waea kōrero 08G2S, ai te ihirangi waro o - 0.08%, e pā ana ki 2% konupora me te iti iho i te 1% silicon.
