He koranu konumohe whakarewa-mate hou he kaha teitei: he rauemi matua mō te whakamama i te mama o te motuka me te whakapai ake i te mahi
E whakaatu ana ngā hua rangahau hou i ngā āhuatanga pai o te koranu Al-Si-Mg-Mn
I roto i te whanaketanga tonu o te umanga motuka, kua noho te whakamama i te taumaha hei huarahi nui ki te whakapai ake i te whai huatanga me te mahi a te pūngao. Hei rauemi mama, kaha-teitei, kei te piki haere te whakamahinga o te koranu konumohe i roto i te hanga motuka. Nō nā tata nei, i puta mai he rangahau mō tētahi koranu Al-Si-Mg-Mn kaha-teitei hou, he tirohanga hou ki te whakamahinga o ngā koranu konumohe i roto i te whakamama i te taumaha o te motuka.
Ngā āhuatanga hou o te koranu Al-Si-Mg-Mn
E ai ki ngā rangahau hou, ko te kaha kume o te koranu Al-Si-Mg-Mn hou i muri i te makanga mate (hei makanga) ka eke ki te 230 ki te 310 MPa, ko te kaha hua he 200 ki te 240 MPa, ā, ko te roanga he tata ki te 0.5%. Ko te whakatutukitanga o tēnei mahi ka whai hua mai i te hanganga o te anga pai. he-AlFeMnSi te āhua me te hanganga eutectic maha-tauine i roto i te koranu. Heoi, he iti ake te roa o te koranu, nā te awe tika o ngā pūwero nui ake me ngā āhua tuarua matotoru te nuinga.
Te whakamahi i te hangarau whakarewa-mate me te whanaketanga o ngā koranu konumohe
Hei tukanga hanga tata-kupenga, he whānuitia te whakamahinga o te whakarewa-mate i roto i te hanga waka, whakawhitiwhiti kōrero, mīhini hangarau me ētahi atu wāhanga nā te mea he nui te pai o te whakaputa, he teitei te tika o te hua me te mahi tino pai. I roto i te tekau tau kua pahure ake nei, he maha ngā wāhanga waka i hangaia i te maitai i te tuatahi kua whakakapia ki ngā wāhanga whakarewa-mate konumohe, e kore e whakaiti noa i te taumaha o te waka, engari ka tutuki hoki ngā whāinga tiaki pūngao me te whakaiti i ngā tukunga.
Te whakapakari i te tikanga me te whakapai ake i te mahi o ngā koranu konumohe
Mā te tāpiri i ngā huānga pēnei i te Mg, Cu, Mn, Zn rānei ki ngā koranu konumohe hei hanga i ngā matū takawaenga pēnei i te AlMgZn, AlMn, Al2Cu rānei, ka taea te whakapai ake i te kaha o te koranu. Ko te pānga whakapakari o ēnei koranu e pā ana ki te whakapakari i te otinga totoka me te whakapūmautanga. E whakaatu ana ngā rangahau mā te tāpiri i te nui o te Mn e tika ana, ehara i te mea ka taea anake te whakaiti i te pokepokea piri, engari ka taea hoki te whakaiti i te āhua o te pokepokea ai. b-Ka taea hoki te whakarerekē i te āhua o te Fe, hei whakapai ake i te mahi a te koranu.
Te rangahau mō te hanganga me ngā āhuatanga o ngā koranu konumohe hou
I hangaia e ngā kairangahau ngā hanganga koranu Al-Si-Mg-Mn me ngā wāhanga whakauru eutectic rerekē mā roto i ngā tātaitanga whakatauira kauwhata wāhanga JMatPro. Mā te tirotiro hanganga moroiti me te tātari āhua whati, i whakakitea te whanaketanga hanganga me ngā āhuatanga mahi o te koranu. Kua kitea e te rangahau ka taea e ngā hanganga eutectic tino pai te whakapai ake i te kaha me te kirihou o ngā koranu, ka whakarato i tētahi huarahi hou hei whakapai ake i te mahi o ngā koranu konumohe.
