Nickel-based wrought superalloys yog ib chav kawm ntawm cov ntaub ntawv ua tau zoo tsim los rau cov khoom siv tshwj xeeb, kev ua haujlwm tsis zoo, thiab kev ruaj ntseg ntawm qhov kub siab, feem ntau siab dua 540 ° C (1000 ° F). Lub sij hawm "wrought" txhais tau hais tias cov alloys tau zoo li tus qauv rau hauv lawv daim ntawv kawg los ntawm cov txheej txheem thermomechanical xws li forging, dov, lossis extrusion, uas ua rau cov qauv zoo, cov qauv coj ua uas muab cov khoom tensile thiab qaug zog piv rau lawv cov cam khwb cia. Lawv yog cov caj qaum ntawm qhov kub-kub rotating Cheebtsam hauv aerospace thiab lub zog tsim hluav taws xob, qhov tsis ua haujlwm tsis yog qhov kev xaiv.

Nickel-raws li corrosion-resistant alloys yog ib chav kawm ntawm cov khoom siv hlau siab tshaj plaws uas tau tsim ua feem ntau los tiv thaiv qhov chaw corrosive. Lawv lub hauv paus yog npib tsib xee (Ni) matrix, uas yog inherently resistant rau ntau corrosives, alloyed nrog rau lwm yam tseem ceeb ntsiab - feem ntau chromium (Cr), molybdenum (Mo), thiab tej zaum tooj liab (Cu) thiab nitrogen (N) - los tsim ib tug ntau yam thiab muaj zog tsev neeg ntawm cov ntaub ntawv rau feem ntau aggression tshuaj thiab muaj kev siv. Lawv yog cov mus-rau kev daws teeb meem thaum stainless hlau tsis txaus.

Iron-based wrought high-temperature alloys yog ib chav kawm ntawm cov khoom siv hlau nrog hlau (Fe) ua lub hauv paus tseem ceeb, tsim kom muaj lub zog zoo thiab ua haujlwm tsis zoo (xws li oxidation) ntawm qhov kub siab, feem ntau nyob rau hauv thaj tsam ntawm 540 ° C txog 760 ° C (1000 ° F txog 1400 ° F). Lub npe "wrought" qhia tias lawv tau zoo li tus txheej txheem thermomechanical xws li kub dov, forging, los yog extrusion, uas ua kom zoo dua lawv cov microstructure los muab kev sib xyaw ua ke ntawm lub zog, ductility, thiab fabricability. Lawv ua hauj lwm raws li tus nqi-zoo thiab muaj ntau yam kev daws teeb meem rau ntau qhov sib txawv ntawm cov kev siv kub-kub, bridging qhov kev sib txawv ntawm cov hlau tsis muaj steel thiab kim nickel lossis cobalt-based superalloys.

Cobalt-based superalloys yog ib chav kawm ntawm cov khoom siv hlau ua tau zoo tsim los tswj cov khoom siv tshwj xeeb, kev ruaj ntseg ntawm qhov chaw, thiab kev tiv thaiv corrosion ntawm qhov kub siab heev, feem ntau tshaj qhov uas cov nickel-based superalloys pib qaug zog. Lawv yog cov khoom siv tseem ceeb rau cov khoom tseem ceeb hauv cov cheeb tsam uas xav tau tshaj plaws, tshwj xeeb tshaj yog nyob rau hauv aerospace, industrial gas turbines, thiab kev kho mob cog. Lawv qhov kev ua tau zoo tshaj plaws yog los ntawm kev muaj zog cobalt-chromium matrix thiab cov ntim siab ntawm cov tawv tawv, refractory carbide hais.
