I-MnCu Alloy

I-Manganese yethusi iwuhlobo lwe-alloy yokumelana nokunemba, evame ukuhlinzekwa ngezintambo, kodwa futhi inani elincane lamapuleti nemicu, enezinhlobonhlobo zokusetshenziswa kuzo zonke izinhlobo zamathuluzi namamitha, ngasikhathi sinye, impahla iyi-ultra. -izinto ezizwelayo ezinomfutho ophezulu, umkhawulo ongaphezulu wokulinganisa ingcindezi ungaba phezulu njengo-500 Pa. Ithusi leManganese linomphumela omuhle wokumelana ne-piezo futhi lisetshenziswa kabanzi ekucindezelweni. izilinganiso endaweni yokushisa ephezulu kanye nephezulu yengcindezi efana nokuqhuma kwamabhomu, imithelela yesivinini esikhulu, ukuphuka okuguquguqukayo kanye nokuhlanganiswa kwezinto ezintsha. Ushintsho lokumelana nethusi le-manganese kanye nengcindezi yangaphandle icishe ilingane nomugqa wokusebenza (okungukuthi, i-piezoresistive coefficient K icishe ingashintshi), futhi izinga lokushisa elilingana ne-coefficient lincane, ngethusi le-manganese njengento ebucayi eyenziwe ngezinzwa, ingabonakala ngomfutho we-high-pressure oguqukayo. isilinganiso siguqulwa sibe yisilinganiso soshintsho lokumelana nethusi le-manganese.
Umphumela we-piezoresistive we-manganese-copper alloys usetshenziselwe ukukala ingcindezi iminyaka engaphezu kwengu-90, futhi ngeminyaka yawo-1960, u-Fuller noPrice, uBernstein no-Keough baba ngabokuqala ukusebenzisa izinzwa ze-manganese-copper ekuhlolweni kwe-high-pressure (shockwave) . Ngemuva kweminyaka yocwaningo lubonisa ukuthi, nakuba i-piezoresistive coefficient of manganese-copper alloy ayiphezulu kakhulu, kodwa ngenxa yokuthi inokuzwela okuphezulu, impendulo esheshayo, ukuhleleka okuhle, ukumelana nokushisa kwe-coefficient kuncane nokunye, kufanelekile kakhulu ukukhiqizwa kwezinzwa ze-ultrahigh-pressure force. Uhla lwayo olusebenzayo lwe-1 ~ 50GPa, okwamanje luwumkhawulo ongaphezulu wokulinganisa ingcindezi yezinzwa zokucindezela okuqondile, ezisetshenziswa kabanzi ekutadisheni izici ze-elastic-plastic wave propagation zezinto zokwakha, ukuphuka okuguquguqukayo, ukuqhekeka kongqimba, ukuguqulwa kwesigaba, iziqhumane nezinye izici ukuqhuma. Kodwa-ke, imikhakha yezokuvikela, yezempi kanye neminye ekhethekile idinga ngokuphuthumayo izingcindezi eziphakeme zokulinganisa okuqondile, futhi inzwa iyadingeka ukuze ibe nokusabela okusheshayo kakhulu. Inqubekelaphambili yocwaningo yezinzwa ze-Mn-Cu kulezi zici ezimbili ifinyezwa kafushane [1].
Ama-alloys e-Cu-Mn asetshenziswa kabanzi ngezinto zokuthambisa futhi ayingxenye yenguquko yesigaba se-thermoelastic martensitic. Lolu hlobo lwe-alloy ku-300-600 ℃ yokwelashwa kokushisa okuguga, inhlangano ye-alloy eya enhlanganweni ye-martensite twinning, kanye nenhlangano yamawele e-martensite ayizinzile ngokwedlulele, lapho ingaphansi kwengcindezi yokudlidliza eshintshanayo izokwenzeka lapho ukuhlelwa kabusha kokunyakaza, ngakho-ke. njengokumunca inani elikhulu lamandla, ukusebenza komthelela wokudambisa . I-Manganese yethusi inomphumela omuhle we-piezoresistive isetshenziswa kabanzi ekulinganisweni kwengcindezi ekushiseni okuphezulu nasezindaweni zokucindezela okuphezulu njengokuqhuma, umthelela wesivinini esikhulu, ukuphuka okuguquguqukayo, ukuhlanganiswa kwezinto ezintsha nokunye. Ukushintsha kwe-manganese yethusi nokucindezela kwangaphandle cishe kuhlobene nomugqa wokusebenza (okungukuthi i-piezoresistive coefficient K icishe ingashintshi), kanti izinga lokushisa elilingana ne-coefficient lincane, ngethusi le-manganese njengento ebucayi eyenziwe ngezinzwa, ingakwazi ukubona isilinganiso esishintshashintshayo somfutho wegazi ophezulu singene isilinganiso sokushintsha kokumelana ne-manganese yethusi.
