MnCu alloy

Manganese tooj liab yog ib yam ntawm precision kuj alloy, feem ntau muab nyob rau hauv cov xov hlau, tab sis kuj muaj ib tug me me daim hlau thiab strips, uas muaj ntau yam kev siv nyob rau hauv txhua yam ntawm cov twj paj nruag thiab meters, tib lub sij hawm, cov khoom yog ib tug ultra. -high-pressure rhiab heev cov ntaub ntawv, lub siab txwv tsis pub ntsuas yuav siab li 500 Pa. Manganese tooj liab muaj ib tug zoo piezo-resistive nyhuv thiab yog dav siv nyob rau hauv lub siab ntsuas hauv Kev kub siab thiab kev kub ntxhov ib puag ncig xws li kev foob pob tawg, kev kub ceev cuam tshuam, dynamic rupture thiab synthesis ntawm cov ntaub ntawv tshiab. Manganese tooj liab kuj hloov pauv thiab sab nraud siab yog kwv yees li kev sib raug zoo ntawm kev sib raug zoo (piv txwv li piezoresistive coefficient K yog ze li qhov qub), thiab qhov kub thiab txias coefficient kuj yog me me, los ntawm manganese tooj liab raws li lub ntsiab lus rhiab ua los ntawm cov sensors, tuaj yeem pom tau los ntawm kev kub siab dynamic siab. kev ntsuas yog hloov mus rau hauv kev ntsuas ntawm manganese tooj liab tsis kam hloov.
Cov nyhuv piezoresistive ntawm manganese-tooj ​​liab alloys tau siv los ntsuas qhov siab rau ntau tshaj 90 xyoo, thiab nyob rau xyoo 1960, Fuller thiab Nqe, Bernstein thiab Keough yog thawj zaug siv manganese-tooj ​​liab sensors rau dynamic high-pressure (shockwave) kuaj. . Tom qab xyoo ntawm kev tshawb fawb qhia tau hais tias, txawm hais tias lub piezoresistive coefficient ntawm manganese-tooj ​​liab alloy tsis siab heev, tab sis vim hais tias nws muaj ib tug siab rhiab heev, ceev teb, zoo linearity, kuj kub coefficient yog me me thiab thiaj li nyob, nws yog heev haum rau lub kev tsim khoom ntawm ultrahigh-pressure force sensors. Nws qhov kev ua tau zoo ntawm 1 ~ 50GPa, tam sim no yog qhov txwv siab ntawm kev ntsuas siab ntawm cov ntsuas hluav taws xob ncaj qha, dav siv hauv kev tshawb fawb ntawm elastic-yas yoj propagation yam ntxwv ntawm cov ntaub ntawv, dynamic tawg, txheej tawg, theem hloov, tawg thiab lwm yam ntawm qhov tawg. Txawm li cas los xij, kev tiv thaiv, tub rog thiab lwm yam tshwj xeeb yuav tsum tau ceev nrooj siab dua rau kev ntsuas ncaj qha, thiab lub sensor yuav tsum muaj cov lus teb ceev heev. Kev tshawb fawb kev nce qib ntawm Mn-Cu sensors nyob rau hauv ob yam no yog luv luv luv [1].
Cu-Mn alloys yog dav siv damping cov ntaub ntawv thiab nyob rau hauv qeb ntawm thermoelastic martensitic theem hloov. Hom alloy no nyob rau hauv 300-600 ℃ rau kev laus thaum tshav kub kub kev kho mob, lub koom haum alloy mus rau lub zoo martensite twinning lub koom haum, thiab lub zoo martensite twinning lub koom haum yog tsis ruaj tsis khov, thaum raug rau alternating vibrational kev nyuaj siab yuav tshwm sim thaum lub rearrangement ntawm lub zog, yog li ntawd. raws li nqus tau ntau lub zog, kev ua haujlwm ntawm cov nyhuv damping. Manganese tooj liab muaj cov txiaj ntsig zoo piezoresistive yog dav siv hauv kev ntsuas siab hauv qhov kub thiab txias ib puag ncig xws li moj tej tawg, kev kub ceev cuam tshuam, dynamic tawg, cov khoom siv tshiab thiab lwm yam. Manganese tooj liab kuj hloov pauv thiab sab nraud siab yog kwv yees li kev sib raug zoo ntawm kev sib raug zoo (piv txwv li piezoresistive coefficient K yog ze li ntawm), thiab qhov kub thiab txias coefficient yog me me, los ntawm manganese tooj liab raws li lub ntsiab lus rhiab ua los ntawm cov sensors, tuaj yeem paub qhov kev ntsuas kub siab rau hauv lub zog. ntsuas ntawm manganese tooj liab kuj hloov.
