Answer
17-7PH (Ubwoko 631) nigice cya austenitike yimvura-ikomera ibyuma bitagira umuyonga bikoreshwa kumasoko yumuraba bisaba imbaraga nyinshi no kurwanya ruswa. Mu miterere ya 'CH900', ibikoresho bigabanywa ubukonje kugeza kuri C hanyuma noneho bigakomera ku $ 900 ^ \ kuzenguruka F $ ($ 482 ^ \ kuzenguruka C $). Ubu buryo bugabanya imvange nziza ya aluminium ($ Ni_3Al $) muri matrise ya martensitike, byongera cyane umusaruro w’amadorari agera ku 190.000 $ kugeza 240.000 $ psi. Umubare mwinshi-kuri-tensile igereranya ituma amasoko ashobora gutandukana cyane adahoraho. Mu kirere cyo mu kirere, iyi metallurgie ikundwa kuruta 302 isanzwe itagira umwanda kuko igumana imiterere yubukanishi ku bushyuhe bugera ku $ 650 ^ \ umuzenguruko F $ ($ 343 ^ \ umuzenguruko C $), itanga uburyo bwiza bwo kwidagadura ugereranije n’ibyuma bya karubone.
