Ingxubevange yeMnCu

Ubhedu lweManganese luhlobo lwealloyi yokumelana nokuchaneka, ngokuqhelekileyo kubonelelwa ngeengcingo, kodwa kunye nenani elincinci lamacwecwe kunye nemicu, enoluhlu olubanzi lokusetyenziswa kuzo zonke iintlobo zezixhobo kunye neemitha, kwangaxeshanye, izinto eziphathekayo ziyi-ultra. -izinto eziphathekayo ezinoxinzelelo oluphezulu, umda ophezulu wokulinganisa uxinzelelo unokuba phezulu njenge-500 Pa. I-Manganese yobhedu inefuthe elihle lokuchasa i-piezo kwaye isetyenziswa ngokubanzi kuxinzelelo. imilinganiselo yobushushu obuphezulu kunye neendawo ezinoxinzelelo oluphezulu ezifana nebhobho yokuqhuma, iimpembelelo zesantya esiphezulu, ukuphuka okuguquguqukayo kunye nokuhlanganiswa kwezinto ezintsha. Utshintsho lokuxhathisa kobhedu lweManganese kunye noxinzelelo lwangaphandle lumalunga nobudlelwane bomsebenzi ohambelanayo (okt. i-coezorenti ye-piezoresistive K iphantse yangaguquguquki), kunye ne-coefficient yokumelana neqondo lobushushu lincinci, ngobhedu lwemanganese njengento enovakalelo eyenziwe ngezinzwa, inokuqondwa ngoxinzelelo oluphezulu loxinzelelo oluguquguqukayo. umlinganiselo uguqulelwa kumlinganiselo wokutshintsha kokuxhathisa ubhedu lwemanganese.
Impembelelo ye-piezoresistive ye-manganese-copper alloys isetyenziselwe ukulinganisa uxinzelelo ngaphezu kweminyaka engama-90, kwaye kwiminyaka ye-1960, i-Fuller ne-Price, uBernstein kunye no-Keough baba ngabokuqala ukusebenzisa i-manganese-copper sensors kuvavanyo lwe-high-pressure (shockwave) . Emva kweminyaka yophando lubonisa ukuba, nangona i-piezoresistive coefficient ye-manganese-copper alloy ayiphezulu kakhulu, kodwa ngenxa yokuba inovakalelo oluphezulu, impendulo ekhawulezayo, umgca olungileyo, i-coefficient yokumelana nobushushu incinci njalo njalo, ifanelekile kakhulu imveliso ye-ultrahigh-pressure force sensors. Uluhlu lwayo olusebenzayo lwe-1 ~ 50GPa, okwangoku ngumda ophezulu wokulinganisa uxinzelelo lwezinzwa zoxinzelelo oluthe ngqo, olusetyenziswa ngokubanzi kuphononongo lweempawu ze-elastic-plastic wave propagation yezixhobo, ukwaphuka okuguquguqukayo, ukuqhekeka komgangatho, ukutshintshwa kwesigaba, iziqhushumbisi kunye neminye imiba. uqhushumbo. Nangona kunjalo, ukhuselo, umkhosi kunye namanye amacandelo akhethekileyo afuna ngokukhawuleza uxinzelelo oluphezulu lokulinganisa ngokuthe ngqo, kwaye inzwa iyadingeka ukuba ibe nempendulo ekhawulezayo. Inkqubela yophando ye-Mn-Cu ye-sensor kule miba mibini ishwankathelwa ngokufutshane [1].
Ii-alloys ze-Cu-Mn zisetyenziswa ngokubanzi izinto zokudambisa kwaye ziyinxalenye yenguqu yesigaba se-thermoelastic martensitic. Olu hlobo lwe-alloy kwi-300-600 ℃ yokuguga unyango lobushushu, umbutho we-alloy ukuya kumbutho we-martensite twinning, kunye nombutho we-martensite twinning awuzinzanga kakhulu, xa uphantsi koxinzelelo lokungcangcazela kuya kwenzeka xa uhlengahlengiso lwentshukumo, ngoko ke njengokufunxa isixa esikhulu samandla, ukusebenza kwesiphumo sokudambisa . Ubhedu lweManganese lunesiphumo esihle se-piezoresistive sisetyenziswa ngokubanzi kumlinganiselo woxinzelelo kwiqondo lobushushu obuphezulu kunye neendawo ezinoxinzelelo oluphezulu ezifana nokuqhushumba, ifuthe lesantya esiphezulu, ukwaphuka okuguquguqukayo, ukuhlanganiswa kwezinto ezintsha njalo njalo. Utshintsho lokuxhathisa ubhedu lweManganese kunye noxinzelelo lwangaphandle lumalunga nobudlelwane bokusebenza okuhambelanayo (okt. i-coezoresistive coefficient K iphantse yatshintsha), kunye ne-coefficient yokumelana neqondo lobushushu lincinci, ngobhedu lwemanganese njengento enovakalelo eyenziwe zizivamvo, inokuqonda umlinganiselo oguqukayo woxinzelelo loxinzelelo oluphezulu kwi umlinganiselo wotshintsho lokumelana nobhedu lwemanganese.
