Muaj ib lub pob nyob hauv qab sab xis ntawm nplooj ntawv kom rov qab mus rau lub rooj ntawm cov ntsiab lus.
Muaj lus hais hauv peb txoj haujlwm: Cov ntaub ntawv tsis txhob dag, tab sis yog tias koj tso siab rau cov lus ceeb toom, lawv yuav dag rau lawv.
Kuv yog Tus Thawj Coj Zoo ntawm Lork Group. Kuv tau siv ze li nees nkaum xyoo hauv High-Kev ntsuas kub ntawm cov hlau, los ntawm cov khoom siv tes tuav mus rau lub rooj zaum OES, thiab los ntawm metallographic microscopes mus rau universal test machines; txhua yam khoom siv zoo li tus phooj ywg qub. Tau ntau xyoo dhau los, kuv tau pom ntau qhov xwm txheej uas cov ntaub ntawv "dhau txhua qhov kev xeem ntawm daim ntawv, tseem ua tsis tiav hauv daim ntawv thov"- tsis yog vim kev dag, tab sis vimcov txheej txheem kev sim lawv tus kheej muaj qhov muag tsis pom lossis cov kauj ruam tseem ceeb tau raug tshem tawm tsis pom zoo.
Tias yog vim li cas, thaum peb npaj los sau daim ntawv no ntawm "Kev Tswj Xyuas Kev Lag Luam thiab Kev Tswj Xyuas Zoo," Kuv hais tias: "Tsis muaj kev lag luam platitudes." Es tsis txhob, kuv hais tias,"Cia peb piav qhia meej meej tias peb ua haujlwm li cas, peb ntsaws qhov khoob, thiab peb ua li cas peb cov neeg siv khoom pom cov txheej txheem nrog lawv tus kheej ob lub qhov muag."Qhov no yog qhov tseeb uas koj tab tom yuav nyeem: siv high -kub alloys raws li cov ntaub ntawv kawm, Kuv yuav tham txog kev tshuaj xyuas zoo thiab kev tswj xyuas kev tswj xyuas zoo uas cuam tshuam rau txhua theem ntawm peb cov kev tswj cov saw hlau. Qhov no tsis yog daim ntawv tshaj tawm kev lag luam, tab sis yog ib tus account ua ntej los ntawm tus kws tshaj lij kev soj ntsuam zoo.
Cia peb pib los ntawm kev sib tham txog peb cov saw saw hlau: Vim li cas peb tsis sib tw ntawm tus nqi?
1+1+1 > 3 - thiab Lork Selections
Tej zaum koj yuav nug: "Vim li cas koj tus nqi siab dua li ntawm lwm tus neeg muag khoom?"
Kuv cov lus teb yog yooj yim:High-Tub kub alloy cov ntaub ntawv siv nyob rau hauv aerospace, kev kho mob, thiab roj thiab roj sectors yog inherently siab -precision thiab txiav-nt. Yog li ntawd, lawv cov nqi yog ib txwm siab dua.
Peb txoj hauv kev tsis yog tsuas yog cobble ua ke peb tus neeg muag khoom pheej yig tshaj plaws muaj. Lawv txoj kev taw qhia-qhov peb hu ua "Lork Select"- nyob ntawm qhov kev xav hauv paus: peb txheeb xyuas tus kws tshaj lij thiab tus khub nruj tshaj plaws ntawm * txhua theem * ntawm tus txheej txheem, thiab tom qab ntawd sib koom ua ke los tsim cov kev daws teeb meem kom zoo.
Peb "cov" no muaj xws li: steel zeb nrog cov kev txawj ntse tshaj plaws hauv steelmaking, qhov chaw kho cua sov nrog cov txheej txheem kev cai tshaj plaws, thiab lub koom haum kuaj nrog cov qauv tsis zoo tshaj plaws. Saib nyob rau hauv kev sib cais, txhua tus khub yuav tsis yog qhov kev xaiv pheej yig tshaj; tsis tau, thaum ua ke, qhov twg 1+1+ los ua ke, tus nqi sib sau deb tshaj qhov suav ntawm nws qhov chaw. Raws li tus neeg saib xyuas zaum kawg hauv cov txheej txheem lees paub, peb tus kheej ua tus saib xyuas qhov kawg, siv kev tswj xyuas kom zoo thoob plaws tag nrho cov khoom xa tuaj thiab ua qhov kev tshuaj xyuas cov khoom kawg.
Kuv Qhov Tseem Ceeb Philosophy:
"1 + 1 + 1 > 3. Lork's Select- tsis yog tsuas yog cov khoom lag luam pheej yig tshaj plaws ua ke, tab sis qhov kev daws teeb meem zoo tshaj plaws, txhais los ntawm kev tshaj lij tsis sib xws thiab cov qauv nruj tshaj plaws."

Kuv yuav tsum qhia meej ib lub ntsiab lus rau kuv cov neeg siv khoom, raws li ntau tus neeg tau kawm qhov no nyuaj heev.
Handheld spectrometers (XRF) tsuas tuaj yeem ntes cov hlau. Lawv yeej tsis muaj peev xwm nrhiav tau.
Cia kuv muab ib qho piv txwv nrog rau High-Tub kub alloys:Inconel 625 thiab 625LCF.
Raws li ib tug handheld spectrometer muaj kev txhawj xeeb, ob qib no yog xyaum "twins" - qhov concentration ranges ntawm lawv thawj alloying ntsiab (xws li Ni, Cr, Mo, thiab Nb) sib tshooj yuav luag tag. Yog hais tias koj yuav tsum luam theej duab lawv nrog ib tug handheld spectrometer, cov kev nyeem ntawv yuav luag zoo tib yam, ua rau nws tsis yooj yim sua kom paub qhov txawv ntawm ob. Txawm li cas los xij, lawv qhov sib txawv tseem ceeb yog qhov tseeb hauv lawvcov ntsiab lus carbonthiabkab kawm:
Standard alloy 625
Cov ntsiab lus carbon tau tso cai txog li 0.10%; nws yog siv nyob rau hauv cov ntawv thov uas yuav tsum tau corrosion kuj thiab siab - kub stability.
Inconel Alloy 625LCF (Low Cycle Fatigue)
Cov ntsiab lus carbon yog nruj me ntsis tswj rauqis dua 0.03%. Tsis tas li ntawd, nws yog qhov yuav tsum tau ua kom nruj ntxiv txog kev suav nrog thiab cov qoob loo loj, ua rau nws tsim tshwj xeeb rau cov khoom tseem ceeb, xws li cov tshuab dav hlau thiab cov roj av hauv dej hiav txwv thiab cov roj sib txuas, uas yuav tsum tiv taus kev kub ntxhov thiab kev co txhua yam.
Yog tias koj tsuas yog tso siab rau ib qho khoom siv spectrometer rau kev tshuaj ntsuam sai, koj yuav xav tias ob cov ntaub ntawv no zoo ib yam. Thaum siv 625LCF nyob rau hauv qhov chaw ntawm tus qauv 625 tej zaum yuav tsis ua rau muaj teeb meem tseem ceeb (tsuas yog ib qho tsis tsim nyog pov tseg ntawm siab- cov khoom ua tau zoo), siv tus qauv 625 nyob rau hauv ib qho tseem ceeb aerospace los yog sib sib zog nqus- daim ntawv thov dej hiav txwv qhov twg 625LCF yuav tsum tau tuaj yeem ua rau muaj kev qaug zog tawg tom qab tsuas yog ob peb puas xuab moos ntawm kev ua haujlwm.
Yog li ntawd, peb cov txheej txheem yog raws li nram no:
