Waea/Rīpene/Toka Ā-aukume Ngāwari Mu 49 (FeNi50)

Ko te koranu nikara rino aukume ngohengohe kei roto i te turanga nikara rino me te maha o ngā huānga Co, Cr, Cu, Mo, V, Ti, Al, Nb, Mn, Si me ētahi atu huānga o te koranu, koinei te koranu nikara rino tino maha ngā whakamahinga, he momo momo me ngā whakaritenga maha, ko te inenga i muri i te pepa maitai silicon me te rino parakore hiko. Ki te whakatauritea ki ētahi atu koranu aukume ngohengohe, he tino teitei te urunga aukume o te koranu i roto i te mara aukume whenua me te iti o te kaha akiaki, ko ētahi koranu he porowhita hysteresis tapawhā, he tino iti te kaha o te aukume toenga me ngā āhuatanga urunga aukume pumau, ā, he kaupapa motuhake tōna.
He pai ngā āhuatanga ārai-waikura me ngā āhuatanga tukatuka o tēnei momo koranu, ā, ka taea te hanga i ngā wāhanga tino tika, pērā i te āhua me te rahi. Nā te mea he teitei ake te ātete o te koranu i te rino parakore me te pepa maitai silicon, ā, he ngāwari te tukatuka hei whitiki angiangi, kia taea ai te whitiki angiangi i raro i te torutoru maikorone, ka whakamahia ki te torutoru MHZ i te auau teitei.
Ko te kaha o te aukume kukū me te pāmahana Curie o te koranu he teitei ake i ngā rauemi aukume ngohengohe ferrite, ā, i roto i te umanga rererangi me ētahi atu umanga hiko ka puta he tairongo teitei, he tika te rahi, he iti te rahinga, he iti te ngaronga i te auau teitei, he pumau te wā me te pāmahana me te mahi a ngā wāhanga hiko motuhake. I roto i ngā whakawhitiwhiti kōrero, he whānuitia te whakamahinga o ngā taputapu, te rorohiko hiko, te mana mamao, te tairongo mamao me ētahi atu i roto i te pūnaha.

Kei roto i te papa aukume ngoikore ngā koranu aukume ngohengohe, he nui te uruhanga me te iti o te kaha akiaki o ngā koranu. He whānuitia te whakamahinga o tēnei momo koranu i roto i ngā hikohiko reo irirangi, ngā taputapu me ngā mita tika, te mana mamao me te pūnaha whakahaere aunoa, ko te nuinga o te whakamahinga o te whakakotahitanga mō te hurihanga pūngao me te tukatuka mōhiohio, he rauemi nui ēnei āhuatanga e rua i roto i te ōhanga ā-motu.

Kupu Whakataki
I raro i te mahi a te aukume ngāwari, ka memeha haere te papa aukume o waho o te koranu aukume, ā, ka memeha haere te kaha o te aukume me ngā koranu aukume i muri i te tango i te papa aukume.
He iti, he whaiti hoki te horahanga o te koropiko hysteresis, ko te kaha akiaki he iti iho i te 800 a/m, he teitei te ātete, he iti te ngaronga o te iahiko hurihuri, he teitei te urunga aukume. Ko te tikanga ka tukatukahia hei pepa me te riipene. I whakaritea te rewa. Ko te nuinga o te wā ka whakamahia mō ngā taputapu hiko, te umanga whakawhitiwhiti kōrero i roto i ngā wāhanga matua (pēnei i te matua whakawhiti, te matua rino whakawhiti, te koiri aukati, me ētahi atu). Ko te koranu aukume ngohengohe e whakamahia whānuitia ana he rino hiko waro iti, te rino eminem, te pepa maitai silicon, te koranu aukume ngohengohe, te rino, te koranu aukume ngohengohe cobalt, te koranu nikara rino silicon ngohengohe, me ētahi atu.

Ngā āhuatanga ā-tinana
I raro i te mahi a te papa aukume o waho, he ngāwari te huri i te kaha o te aukume (aukume) me te ngaronga taketake o te koranu aukume. He iti, he whaiti te rohe koropiko hysteresis, he iti iho i te 10 Oe te kaha akiaki (Hc) (tirohia te koranu tika). I te mutunga o te rautau 19, i hangaia he motuka maitai waro iti me te matua whakawhiti. I te tau 1900, ka tere te whakakapi i te maitai waro-iti i te pepa maitai silicon teitei ake, e whakamahia ana i roto i te hanga hua ahumahi hiko. I te tau 1917, ka urutau te koranu Ni - Fe ki ngā hiahia o nāianei o te pūnaha waea. Kātahi ka urutau te koranu Fe - Co me ngā āhuatanga aukume rerekē (1929), te koranu Fe - Si - Al (1936) me te koranu Fe - Al (1950) ki te whakatutuki i te kaupapa motuhake. I te tau 1953, ka tīmata a Haina ki te hanga pepa maitai silicon wera. I te mutunga o te tekau tau '50, ka tīmata ki te ako i te Ni - Fe me te koranu aukume ngohengohe pērā i te Fe, Co, 60, ka tīmata te whakaputa i ētahi o ngā koranu aukume ngohengohe nui. I te tekau tau 70, ka hangaia te koranu makariri. whitiki maitai silicon.
Ko ngā āhuatanga aukume o te koranu aukume ngohengohe ko: (1) te kaha akiaki (Hc) me te iti o ngā ngaronga hysteresis (Wh);(2) he teitei ake te ātete (rho), he iti te ngaronga o te iahiko hurihuri (We);(3) te urunga tuatahi (mu 0) me te teitei rawa

Ngā momo matua o
Ka taea te wehewehe ki te rino hiko waro iti me te rino Eminem, te pepa maitai silicon, te rino nikara me te koranu aukume ngohengohe, te rino, te koranu aukume ngohengohe cobalt, te rino, te koranu aukume ngohengohe silicon konumohe, me ētahi atu. Mō te ahumahi hiko, e whakamahia ana i roto i te papa aukume teitei me te aukume teitei me te ngaronga matua iti o te koranu. I roto i te ahumahi hiko, e whakamahia ana i roto i te papa aukume iti, waenga rānei me te urunga teitei me te kaha iti o te koranu. I raro i te auau teitei me tango te rīpene angiangi, te ātete teitei ake rānei o te koranu. He pepa, he rīpene rānei e whakamahia whānuitia ana.
