Tilmaamaha Alaabta
GH907 waa roobab Fe-Ni-Co ah oo adkeynaya daawaha heerkulka sare leh balaadhinta hoose iyo qallafsanaanta, lagu xoojiyay niobium, titanium, silicon iyo boron raad. Daawadu waxa ay leedahay awood sare, is-ballaadhineed hoose, iska caabin wanaagsan oo daalka kulaylka iyo qabowga leh iyo ku dhawaad balaastigga joogtada ah ee ka hooseeya 650°C. Barta Curie waxay u dhaxaysaa 400°C ilaa 4000°C. Daawadu waxay leedahay koronto fidineed hoose iyo iska caabin wanaagsan oo daalka kulul iyo qabowga leh. Barta Curie waxay ku jirtaa inta u dhaxaysa 400 ℃-450 ℃. Isku-dubbaridka balaadhinta daawaha asal ahaan waxba kama beddelin barta Curie. Daawaha ayaa ku habboon wax soo saarka ee dhammaan noocyada kala duwan ee duulista iyo aerospace engine giraanta iyo majaladaha ka hooseeya 650 ℃, iyo waxyaabaha ugu muhiimsan waxaa ka mid ah baararka, foornada, taarikada iyo strips. Maadaama daawadu aanay ku jirin walxaha chromium iyo aluminium, caabbinta oksaydhka heerkulka sare waa mid liidata. Marka la isticmaalo wakhti dheer oo ka sarreeya 700 ° C, dahaar ilaalin habboon waa in la mariyaa. Dusha daawaha waa la toogan karaa, taasoo wanaajisa daalka leexashada wareega qiyaastii 18%.
