MnCu Alloy

Manganese koporo ke mofuta oa alloy e nepahetseng ea ho hanyetsa, hangata e fanoang ka lithapo, empa hape le palo e nyane ea lipoleiti le likhoele, tse nang le ts'ebeliso e fapaneng ea mefuta eohle ea lisebelisoa le limithara, ka nako e ts'oanang, thepa ke ea ultra. -lisebelisoa tse nang le khatello e phahameng ea khatello, moeli o ka holimo oa tekanyo ea khatello e ka ba holimo ho 500 Pa. Koporo ea manganese e na le phello e ntle ea ho hanyetsa piezo 'me e sebelisoa haholo khatellong. litekanyo libakeng tsa mocheso o phahameng le oa khatello e phahameng joalo ka ho phatloha ha libomo, liphello tse phahameng ka potlako, ho phatloha ho matla le ho kopanya lisebelisoa tse ncha. Phetoho ea ho hanyetsa koporo ea manganese le khatello ea kantle e batla e le kamano ea ts'ebetso (ke hore, piezoresistive coefficient K e batla e sa fetohe), 'me mocheso oa mocheso oa ho hanyetsa o nyane, ka koporo ea manganese e le ntho e hlokolosi e entsoeng ka li-sensor, e ka bonoa ka khatello e matla ea khatello e phahameng. tekanyo e fetoloa tekanyong ea phetoho ea koporo ea manganese.
Phello ea piezoresistive ea manganese-copper alloys e 'nile ea sebelisoa ho lekanya khatello ka lilemo tse fetang 90,' me lilemong tsa bo-1960, Fuller le Price, Bernstein le Keough e bile bona ba pele ba ho sebelisa li-sensor tsa manganese-copper litekong tse matla tsa khatello e phahameng (shockwave). . Ka mor'a lilemo tse ngata tsa lipatlisiso li bontša hore, le hoja piezoresistive coefficient ea manganese-copper alloy ha e phahame haholo, empa hobane e na le kutloisiso e phahameng, karabelo e potlakileng, linearity e ntle, mocheso oa ho hanyetsa mocheso o monyenyane joalo-joalo, o loketse haholo tlhahiso ea li-sensor tsa ultrahigh-pressure force. Mofuta oa eona o sebetsang oa 1 ~ 50GPa, hajoale ke moeli o kaholimo oa tekanyo ea khatello ea li-sensor tsa khatello e tobileng, e sebelisoang haholo thutong ea li-elastic-plastiki wave propagation litšobotsi tsa lisebelisoa, ho robeha ho matla, ho phatloha ha lera, phetoho ea mekhahlelo, liqhomane le likarolo tse ling tsa ho phatloha. Leha ho le joalo, ts'ireletso, sesole le likarolo tse ling tse khethehileng li hloka ka potlako likhatello tse phahameng bakeng sa tekanyo e tobileng, 'me sensor e hlokeha ho ba le karabo e potlakileng haholo. Tsoelo-pele ea lipatlisiso tsa li-sensor tsa Mn-Cu likarolong tsena tse peli li akaretsoa ka bokhutšoanyane [1].
Li-alloys tsa Cu-Mn li sebelisoa haholo ka lisebelisoa tsa pholiso 'me ke karolo ea phetoho ea karolo ea thermoelastic martensitic. Mofuta ona oa motsoako oa 300-600 ℃ bakeng sa phekolo ea mocheso oa botsofali, mokhatlo oa alloy ho mokhatlo o hlophisitsoeng oa martensite twinning, le mokhatlo o hlophisitsoeng oa martensite o tsitsitseng o tsitsitse haholo, ha o tlas'a khatello ea khatello ea maikutlo e tla etsahala ha ho hlophisoa bocha ha motsamao, kahoo. e le ho monya matla a mangata, ts'ebetso ea phello e senyang . Koporo ea manganese e na le phello e ntle ea piezoresistive e sebelisoa haholo ho lekanya khatello ka mocheso o phahameng le maemo a phahameng a khatello e kang ho phatloha, ho phatloha ka lebelo le phahameng, ho robeha ho matla, motsoako o mocha oa thepa joalo-joalo. Phetoho ea ho hanyetsa koporo ea manganese le khatello ea kantle e batla e le kamano ea ts'ebetso (ke hore piezoresistive coefficient K e batla e sa fetohe), 'me coefficient ea mocheso oa ho hanyetsa e nyane, ka koporo ea manganese e le ntho e hlokolosi e entsoeng ka li-sensor, e khona ho lemoha tekanyo e matla ea khatello e phahameng ea khatello ea maikutlo. tekanyo ea phetoho ea manganese koporo ea ho hanyetsa.
