5.Kev ua haujlwm vuam zoo
Inconel 718 siab kub hlau metallographic qauv:
Alloy 718 muaj cov qauv austenitic thiab "theem tsim tom qab nag lossis daus hardening muaj cov khoom siv zoo heev. δ theem tsim ntawm cov ciam teb thaum kho cua sov muab nws zoo plasticity.
Inconel 718 siab kub alloy corrosion kuj:
Alloy 718 muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion tawg thiab pitting corrosion nyob rau hauv qhov kub thiab txias ib puag ncig. Alloy 718 muaj qhov tshwj xeeb zoo oxidation tsis kam ntawm qhov kub thiab txias.
Inconel 718 siab kub alloy txheej txheem kev ua tau zoo thiab yuav tsum tau:
Thermal ua
Qhov kev kho cua sov uas tsim nyog yog 1120-900 degree, thiab txoj kev ua kom txias tuaj yeem yog dej quenching lossis lwm txoj kev ua kom txias sai. Tom qab kev kho cua sov, annealing yuav tsum tau nqa tawm nyob rau hauv lub sij hawm los xyuas kom meej kev ua tau zoo. Thaum lub sij hawm thermal ua, cov khoom yuav tsum tau rhuab mus rau lub sab sauv txwv ntawm ua kub. Txhawm rau kom ua tiav plasticity thaum ua tiav, qhov kawg ua haujlwm kub thaum deformation mus txog 20% yuav tsum tsis txhob qis dua 960 degree.
Ua haujlwm txias
Kev ua haujlwm txias yuav tsum tau ua tom qab kev daws teeb meem. Kev ua haujlwm hardening yog ntau dua li austenitic stainless hlau, yog li cov khoom siv ua haujlwm yuav tsum tau hloov kho raws li qhov xav tau, thiab cov txheej txheem annealing nruab nrab yuav tsum tau ua thaum lub sijhawm ua haujlwm txias.
