Refractaloy 26 is Fe - NI - Co - Cr precipitation kuomesa mhando deformation yeyakanyanya tembiricha alloy, kushandiswa kwenguva refu kweC - 570 ℃ tembiricha ye540 ℃, tembiricha yepamusoro inogona kusvika 677 C, wedzera chinhu cheCr, mo alloy. yakasimba mhinduro kusimbisa, yakakwirira kusvika yakaderera titanium, aluminium fomu y kuchembera kusimbisa chikamu, nepo kuchera zvinhu zvakagadzirwa netitanium, aluminium solubility mune yakasimba mhinduro inoderedzwa, inokurudzira y chikamu chekunaya kwemvura kuwedzera, kuitira kuvandudza kugadzikana kwekupisa kwey, kuderedza. y 'chikamu chesimba rekukanganisa.
Iyo inosanganiswa zvimiro zvealloy yakakwirira, ine yakanakisa tensile kuramba, simba kuzorora uye zvinokambaira kuramba, hapana notch senitivity.

Iyo alloy yakashandiswa mukugadzirwa kwevhu turbine turbine yakavharirwa, pasi pemamiriro emhepo ye540 ℃ ~ 570 ℃ inogona kushanda kweanopfuura maawa 100,000, mamiriro ekushandisa akanaka.Similar alloys anoshandiswa kunze kwenyika kugadzira aero turbine injini yakaoma zvikamu. uye bladesThe alloy ine plasticity yakanaka pane yepakati tembiricha, iyo inogona kuderedza kuputsika kwezvikamu nekuda kwekugara uye kukambaira mukushandiswa kwenguva refu.Hapana TCP inokuvadza chikamu chakawanikwa mune alloy mushure mekukwegura kwenguva refu kana kushushikana kwenguva refu mukukwegura tembiricha range
