Inconel 718 alloy yog dav siv rau hauv ntau qhov chaw thiab siv nyob rau hauv ntau qhov chaw vim nws cov khoom zoo heev. Raws li txoj cai, Inconel 718 alloy siv nyob rau hauv ib puag ncig sib txawv xav tau kev tsim cov thev naus laus zis, thiab microstructure thiab cov khoom ntawm Inconel 718 alloy tau los ntawm kev siv tshuab sib txawv kuj txawv. Yog li ntawd, nws yog qhov tseem ceeb heev los tsim cov txheej txheem tsim nyog rau kev thov ntawm Inconel 718 alloy.
Deformation yog ib qho tseem ceeb txhais tau tias kom optimize microstructure thiab txhim kho cov khoom ntawm cov nickel-based alloys. Cov kev tshawb fawb yav dhau los ntawm Inconel 718 alloy feem ntau tsom rau qhov kub compression thiab creep: Txawm li cas los xij, cov nyhuv ntawm qhov txias deformation ntawm microstructure ntawm Inconel 718 alloy tsis tshua muaj qhia. Tshwj xeeb, qhov tshwm sim ntawm qhov txias dov rau ntawm tus cwj pwm nag lossis daus ntawm Inone1 718 alloy mesophase tseem muaj teeb meem.
Tsis tas li ntawd, yav dhau los, txoj hauv kev los ntawm kev kawm cov nag lossis daus tus cwj pwm ntawm mesophase yog qhov yooj yim, txwv rau XRD thiab kev soj ntsuam metallographic, thiab kev tshawb fawb tob ntxiv yog xav tau ceev. Electron beam welding, raws li lub zog siab-density fusion vuam tshuab, tau siv dav hauv kev sib txuas ntawm Fe-Ni-based alloys. Piv nrog cov txheej txheem vuam tsoos, electron beam welding muaj qhov zoo ntawm qhov nqaim weld pas dej ua ke thiab thaj chaw muaj kev kub ntxhov, thiab me me deformation vim lub zog qis ntawm electron beam vuam.
Tsis tas li ntawd, vim nws lub zog ceev ceev, kev vuam ceev tuaj yeem ua tiav. Txawm li cas los xij, kev sib cais ntawm interdendritic Nb ua rau kev tsim ntawm Laves theem thiab tsim cov microcracks nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam, uas yog lub shortcoming ntawm electron beam vuam.
Tam sim no, ntau cov kev tshawb fawb nrhiav qhov zoo heev microstructure thiab cov khoom ntawm weldments los ntawm kev hloov lub zog tawm tswv yim thiab kev kho cua sov tom qab vuam. Lub hauv paus hlau thiab vuam ceev kuj yog ib qho tseem ceeb cuam tshuam rau lub vuam. Nyob rau hauv daim ntawv no, lub zog ntawm lub hauv paus hlau thiab vuam ceev ntawm electron beam welding ntawm Tncone1 718 alloy muaj qhov tseem ceeb tswv yim tseem ceeb rau optimizing qhov kev ua tau zoo ntawm weldment.
Inconel 718 yog lub zog kub-resistant nickel-raws li alloy nrog zoo heev kub-lub zog, siab kub hardness thiab corrosion kuj. Nws tuaj yeem ua haujlwm ntev nyob rau hauv qhov kub thiab txias. Nws tau siv dav hauv kev lag luam aerospace, turbine cav thiab lwm yam kev lag luam hauv kev lag luam aviation.
Kev tsim cov khoom, tshuaj xyuas cov khoom siv kho tshuab, microstructure ntawm Inconel 718 thiab nws cov kev cuam tshuam ntawm kev ua haujlwm ntawm kev txiav, thiab ua tiav cov kev tshawb fawb soj ntsuam. Cov txiaj ntsig ntawm kev hnav, cov txiaj ntsig kev sim qhia tau hais tias cov ntsiab lus carbon hauv Tncone]718 ua lub luag haujlwm tseem ceeb hauv kev hnav cov cuab yeej flank. Kev txiav cov riam kom raug thaum lub sij hawm tus txheej txheem thiab ua rau cov nplej tom qab kev puas tsuaj los txo cov machinability ntawm cov khoom.
SSM tsim cov flanges hauv txhua qib khoom, suav nrog Hastelloy C276 C22 B2 B3 C2000 X, Inconel600 601 625, Incoloy800 800}H 800HT 826 926, Monel400, Alloy 20, Alloy 31, duplex stainless hlau S32205 S31803 S32750 904L 254SMO, stainless hlau 304 304L 304H 316 316L 316H 316Ti 317 317L 347 347}H 310 310H, Alloy steel A182 F5 F9 F11 F12 F22 F91, Carbon steel A694 F42 F52 F65 F70 A105N A350 LF2 LF3, Titanium Gr.2, thiab lwm yam.
