Nickel-raws li casting high-temperature alloy yog ib qho tseem ceeb ntawm lub tshav kub-kub alloys, nyob rau hauv tag nrho cov hom ntawm precision castings ntau lawm txheej txheem muaj ib tug tseem ceeb kom zoo dua, lub ntsiab yog vim li cas cov khoom no yog resistant rau high kub, siab oxidation. kuj thiab corrosion kuj muaj zog. Thaum ntxov npib tsib xee-raws li high-temperature alloys yog feem ntau deformation alloys, nyob rau hauv lub lig 1950s, nrog rau kev loj hlob ntawm aero-engine technology, lub cav turbine Cheebtsam ntawm qhov kub thiab txias peev xwm ntawm qhov yuav tsum tau ntawm ntau thiab ntau high-temperature alloys, uas. tso rau pem hauv ntej cov kev xav tau siab dua rau lub zog thiab kev siv kub. Thiab txhim khu cov nickel-raws li high-temperature alloy lub zog yog los txhim kho cov hlau alloying degree, uas ua rau cov nickel-raws li high-temperature alloys yog ntau thiab nyuaj rau deform los yog txawm tsis tau deformed, tsuas yog siv rau casting txheej txheem ntau lawm. . Tsis tas li ntawd, nrog txoj kev loj hlob ntawm lub cav hniav tsim tshuab, qhov tshwm sim ntawm hollow cua zaj duab xis qhov txias hniav. Qhov no hollow hniav nrog complex puab kab noj hniav, tsuas yog tsim los ntawm peev casting txheej txheem. Nyob rau hauv qhov kev thov no, domestic thiab txawv teb chaws maj mam tsim ib tug series ntawm npib tsib xee-raws li casting high kub alloy qib nrog zoo kub kev kawm.
Nickel-based high-temperature alloys tau pom thawj zaug hauv tebchaws United Kingdom thaum ntxov 1940s, thiab lawv siv dav hlau aviation coj qhov tseem ceeb ntawm cov khoom siv hlau rau kev mloog ntawm ntau cov neeg tsim khoom lag luam. Lub UK thawj zaug tsim cov nickel-based alloy Nimonic75 (Ni-20Cr-0.4Ti) hauv xyoo 1941, thiab ntev tom qab ntawd, cov teb chaws tsim kho xws li Asmeskas thiab USSR tau ua tiav hauv kev tsim cov hlau zoo sib xws. , thaum Tuam Tshoj tsim ib co alloys nrog tib yam khoom nyob rau hauv lig 1950s.
Kawm txog kev txhim kho keeb kwm ntawm nickel-based casting high-temperature alloys nws tsis yooj yim rau nrhiav, nws yog kwv yees li ob qho kev qhia ntawm txoj kev tshawb fawb: ib qho yog los ntawm kev hloov kho thiab kev sib xyaw ntawm cov hlau alloy, kev kawm ntawm cov ntsiab lus sib txawv ntxiv tshaj qhov cuam tshuam. ntawm alloy kev ua tau zoo, thiab tom qab ntawd nkag mus rau cov ntsiab lus zoo thiab muaj pes tsawg leeg; ob yog los ntawm cov nickel-raws li casting high-temperature alloys txheej txheem ntau lawm, kev ua kom zoo ntawm cov khoom siv ntau lawm thiab kev txhim kho, txhim khu cov alloy kev npaj technology. Xws li thaum ntxov xyoo 1950, cov kws tshawb fawb los ntawm ntau qhov kev sim kev tshawb fawb, kev tshawb fawb thiab kev txhim kho ntawm lub tshuab nqus tsev smelting txheej txheem, qhov tshwm sim thiab kev loj hlob ntawm cov txheej txheem thev naus laus zis no rau kev npaj cov nickel-based casting high-temperature alloys los muab cov txheej txheem ntawm cov txheej txheem. kev ruaj ntseg; 1960s, tsim lub teb chaws los ntawm kev tshawb fawb, muab tso rau pem hauv ntej lub peev casting txheej txheem, zus tau tej cov ntau ntawm casting alloys nrog zoo high-temperature kev ua tau zoo. Nyob rau hauv lub xyoo tom ntej, ib co ib leeg-crystal casting high-temperature alloys nrog zoo-kub kev ua tau zoo tau tsim successively. Nrog rau txoj kev loj hlob ntawm aerospace engine technology, npib tsib xee-raws li casting high-temperature alloys kuj muaj ntau dua yuav tsum tau. Yog li ntawd, los ntawm thaum ntxov 1950s mus rau thaum xaus ntawm lub 1990s ntau tshaj li 40 xyoo, nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab kev loj hlob muaj peev xwm, npib tsib xee-based casting high-temperature alloys kev ua tau zoo thiab kev siv qhov kub thiab txias kuj yog ntau dua, daim ntawv thov teb yog ntau thiab dav.
