MnCu Alloy

Manganese mhangura imhando yekunyatso kupikisa alloy, inowanzo kupihwa muwaya, asiwo shoma shoma yemahwendefa uye mitsetse, iyo ine huwandu hwakasiyana hwekushandisa mumhando dzese dzezviridzwa nemamita, panguva imwe chete, zvinhu zvacho ndeye Ultra. -high-pressure sensitive material, muganho wepamusoro wekuyera kudzvinyirira unogona kusvika pa 500 Pa. Manganese mhangura ine piezo-resistive effect yakanaka uye inoshandiswa zvakanyanya mukudzvinyirira. zviyero munzvimbo dzekupisa uye dzepamusoro-soro dzakadai sekuputika kwebhomba, kukurumidza-kukanganisa, kuputika kwemasimba uye kuumbwa kwezvinhu zvitsva. Shanduko yeManganese yemhangura yekudzivirira uye kudzvanywa kwekunze kunenge mutsara wekuita hukama (kureva piezoresistive coefficient K inogara isingachinji), uye tembiricha yekudzivirira idiki, nemhangura yemanganese sechinhu chinonzwisa tsitsi chakagadzirwa nemasensor, inogona kuzadziswa neiyo dynamic high-pressure pressure. kuyerwa kunoshandurwa kuita kuyerwa kwemanganese mhangura yekuramba shanduko.
Iyo piezoresistive mhedzisiro yemanganese-mhangura alloys yakashandiswa kuyera kudzvanywa kweanopfuura makore makumi mapfumbamwe, uye muma1960, Fuller uye Price, Bernstein naKeough ndivo vakatanga kushandisa manganese-copper sensors kune dynamic high-pressure (shockwave) kuyedza. . Mushure memakore ekutsvagisa kunoratidza kuti, kunyangwe iyo piezoresistive coefficient ye manganese-copper alloy haina kunyanya kukwira, asi nekuti ine yakanyanya senitivity, kukurumidza kupindura, mutsara wakanaka, kupikisa tembiricha coefficient idiki uye zvichingodaro, yakakodzera kwazvo kugadzirwa kwe ultrahigh-pressure force sensors. Yayo inoshanda mhando ye1 ~ 50GPa, parizvino ndiyo yekumusoro muganho wekuyerwa kuyerwa kweyakananga kumanikidza sensors, yakashandiswa zvakanyanya mukudzidza kweelastic-plastiki wave kuparadzira maitiro ezvigadzirwa, kutsemuka kwesimba, kutsemuka kwegumbo, nhanho shanduko, zvinoputika uye zvimwe zvinhu zve. kuputika. Nekudaro, dziviriro, mauto uye mamwe masekete akakosha anofanirwa kukurumidza kudzvinyirirwa kuyera kwakananga, uye sensor inofanirwa kuve nemhinduro inokurumidza. Kufambira mberi kwekutsvagisa kweMn-Cu sensors mune izvi zvinhu zviviri zvinopfupikiswa [1].
Cu-Mn alloys anoshandiswa zvakanyanya kunyorovesa zvinhu uye ari echikamu che thermoelastic martensitic chikamu shanduko. Iyi mhando yealloy mu300-600 ℃ yekuchembera kupisa kurapwa, iyo alloy sangano kune yakanaka martensite twinning sangano, uye iyo yakanaka martensite twinning sangano haina kugadzikana zvakanyanya, kana ichiiswa kune alternating vibrational kusagadzikana kuchaitika kana kurongekazve kwekufamba, saka. sekutora huwandu hwesimba, kuita kwekunyorovesa maitiro . Manganese mhangura ine yakanaka piezoresistive mhedzisiro inoshandiswa zvakanyanya mukuyerwa kuyerwa mukupisa kwepamusoro uye nzvimbo dzekumanikidza dzakaita sekuputika, kumhanyisa kumhanya, kutsemuka kwesimba, kuumbwa kwezvinhu zvitsva uye zvichingodaro. Manganese copper kuramba shanduko uye kumanikidza kwekunze kunenge mutsara wekuita hukama (kureva kuti piezoresistive coefficient K inogara isingachinji), uye tembiricha yekudzivirira idiki, nemhangura yemanganese sechinhu chinonzwisa tsitsi chakagadzirwa nemasensor, inogona kuona iyo ine simba yakanyanya kudzvanywa kuyerwa mukati. kuyerwa kwemanganese mhangura kuramba shanduko.
