Chromium Nickel Alloy Ekisuulibwa Ekiziyiza Ebbugumu Ekiziyiza Okusuula
Okusinziira ku matrix elements zisobola okwawulwamu ekyuma ekisinziira ku kyuma ekiyitibwa superalloy, nickel based superalloy ne cobalt based superalloy. Inconel x-750 Alloy nickel-Chromium Alloy ekyuma ekipande ekyekulungirivu ekikozesebwa mu nickel-okusinziira ku bbugumu eriziyiza ebbugumu kuyinza okwawulwamu deformation superalloy, cast superalloy ne powder metallurgy superalloy okusinziira ku nkola y’okuteekateeka. Okusinziira ku nkola y’okunyweza, waliwo ekika ky’okunyweza eky’okugonjoola ekikalu, ekika ky’okunyweza enkuba, ekika ky’okunyweza okusaasaana kwa okisayidi n’ekika ky’okunyweza fiber. Superalloy esinga kukozesebwa mu kukola ebitundu by’ebbugumu eringi nga ebiwujjo bya ttabiini, ebiwujjo ebilungamya, disiki za ttabiini, disiki za kompyuta ez’amaanyi n’ebisenge eby’okwokya eby’ennyonyi, ttabiini z’emmeeri ne ggaasi z’amakolero. Era ekozesebwa mu kukola ebyuma ebikyusa amaanyi ng’emmotoka z’omu bbanga, ebyuma ebikozesebwa mu kukola amafuta n’okukyusa amanda.
Enkola y'okukola .
High-Ekyuma ekibugumye nga tewali aluminiyamu ne titanium kitono, okutwalira awamu nga tukozesa ekikoomi kya arc eky’amasannyalaze oba ekitali-okusaanuusa ekikoomi kya vacuum induction. Inconel x-750 nickel-based alloy nickel-Chroy alloy steel plate round rod ne aluminium, titanium high superalloy Singa okusaanuusa mu bbanga, okufiirwa kw’ekintu si kyangu kufuga, ggaasi n’okuyingiza mu bingi, kale okusaanuusa vacuum kulina okukozesebwa. Okwongera okukendeeza ku biri mu kuyingiza n’okulongoosa embeera y’okugabanyaamu okuyingiza n’enteekateeka y’okufuuka ekiristaayo (crystallization organization) ya Ingot, enkola ya duplex okugatta okusaanuusa n’okusaasaanya eby’okubiri bisobola okutwalibwa. Ebikulu eby’okusaanuusa ebikoomi by’amasannyalaze, ekikoomi ky’okuyingiza empewo (vacuum induction furnace) n’ekikoomi ky’ekikoomi ekiyitibwa vacuum induction furnace; Ebikulu eby’okugaana okuzzaamu amaanyi bye byo ekikoomi eky’okwekozesa n’ekikoomi eky’amasannyalaze.
Solid solution reinforced alloy and alloy ingot erimu aluminiyamu ne titanium wansi (omuwendo gwonna ogwa aluminiyamu ne titanium guli wansi wa 4.5%) guyinza okujingirira ku billet; Aluminiyamu alimu titanium high alloy alina okunyigirizibwa oba okuyiringisibwa mu billet, n’oluvannyuma n’ayokya okuyiringisibwa mu bintu, ebintu ebimu byetaaga okwongera okuyiringisibwa mu nnyonta oba okusika ennyonta. Ekintu ekiyitibwa ‘alloy ingot’ oba ekintu kya keeki ekirimu dayamita ennene kirina okujingirira ‘hydraulic press’ oba ‘fast forging hydraulic press’.
Alloys ezirina℃ya aloy ate nga si nnyangu ku deform mu kiseera kino zikozesebwa nnyo mu precision casting, nga casting turbine blades ne guide blades. Okusobola okukendeeza oba okumalawo ensalosalo y’empeke perpendicular ku stress axis mu casting alloy n’okukendeeza oba okumalawo loose, directional crystallization process ekoleddwa mu myaka egiyise. Enkola eno efuula empeke okukula mu ndagiriro ya kirisitaalo mu kiseera ky’okunyweza aloy okufuna obutafaali bwa ssiringi obukwatagana obutaliimu nsalosalo ya mpeke ya transverse. Embeera y’enkola enkulu ey’okutuuka ku kufuuka ekiristaayo eky’obulagirizi kwe kuteekawo n’okukuuma embeera ennene emala ey’ebbugumu ery’ekyekulungirivu n’embeera ennungi ey’okusaasaana kw’ebbugumu ery’ekyekulungirivu wakati wa layini y’omutendera gw’amazzi ne layini ya phase enkalu. Okugatta ku ekyo, okusobola okumalawo ensalo z’empeke zonna, enkola y’okukola ekyuma ekimu eky’ekika kya crystal blade erina okusomesebwa.
Enkola y’ebyuma eby’obuwunga, okusinga ekozesebwa okukola ekika ky’enkuba ekinywezeddwa n’ekika kya oxide ekinywezeddwa eky’ekika kya superalloy. Enkola eno esobola okufuna obuveera oba wadde superplasticity.
Enkola y’okujjanjaba okujjuvu kwa superalloy ekwatagana nnyo n’enteekateeka ya aloy, era ekitongole kifugibwa enkola y’ebbugumu ery’ekyuma. Okutwalira awamu aloy za supertemperature zeetaaga okulongoosebwa mu bbugumu. Enkuba-Aloyizi ezinywezeddwa zitera okujjanjabibwa solid solution n’obujjanjabi obukaddiye. Solid solution reinforced alloy yokka okuyita mu solid solution treatment. Alloy ezimu zirina okuyita mu bujjanjabi bumu oba bubiri obw’omu makkati nga tezinnaba kukaddiwa. Enzijanjaba ya solid solution yasooka kukolebwa okusaanuusa omutendera ogwokubiri mu matrix ya alloy okutuuka ku .
Mu nkola y’okukaddiwa, , carbide (cobalt base alloy) n’ebirala ebinywezeddwa mu mutendera ogw’okutonnya kyenkanyi, olwo okusobola okufuna obunene bw’empeke ezisaanidde okukakasa nti ebbugumu lingi eririnnya n’okusigala nga linywerera.
Ebbugumu ly'okulongoosa solution solution okutwalira awamu liri 1040 ~ 1220℃. Kiba kingi .
