Answer
Kuri 550 ° C, A286 (icyuma-fatizo superalloy) igera kumupaka wacyo kugirango ikore neza. Itanga ruswa nziza ariko ikababazwa no kwihuta kwihuta no gutakaza imitwaro ($> 15 \% $) kubushyuhe burambye hejuru ya 500 ° C. Inconel X-750, nikel-chromium ivanze, ni imvura igakomera hamwe na aluminium na titanium kugirango igabanye $ \ gamma '$ icyiciro cyimvura. Iyi mvura igabanya pin dislocations, itanga imbaraga zirwanya imbaraga zo kuruhuka. Kuri 550 ° C, X-750 mubisanzwe irerekana munsi y $ 5 \% $ gutakaza imitwaro mumasaha 1.000. Kubisabwa bya kirogenike, A286 ikomeza kuba ihindagurika, mugihe X-750 ihitamo kubera ubushyuhe bwayo bwo hejuru bwa okiside hamwe nuburinganire bwimiterere igera kuri 700 ° C (hamwe no kuvura ubushyuhe bukwiye # 1).
