Qhov txawv ntawm Inconel 925 thiab 718 yog dab tsi?
Incoloy 925 thiab Inconel 718 yog siab - zog npib tsib xee alloys, tab sis lawv qhov sib txawv tseem ceeb nyob rau hauv lawv cov ntsiab lus nickel thiab nqi: Inconel 718 muaj cov ntsiab lus nickel ntau dua (50-55%) thiab muaj cov ntsiab lus ntxiv dag zog xws li niobium, ua rau nws muaj zog dua tab sis kuj yog ib qho kev xaiv kim dua rau kev lag luam; thiab thaum Incoloy 925 muaj cov ntsiab lus nickel qis (38-46%) thiab cov ntsiab lus hlau ntau dua, ua rau nws muaj txiaj ntsig zoo dua.
Puas yog Inconel 718 muaj zog dua titanium?
Inconel 718 muaj lub zog tensile ntawm 1,375 MPa thaum Ti-6Al-4V titanium alloy (siab tshaj plaws-lub zog), muaj lub zog tensile ntawm ib ncig ntawm 1,170 MPa. Thaum qhov no yog lub zog qis dua qhov muaj zog tshaj Inconel alloys, ntau yam khoom siv yuav tsum tau txiav txim siab hauv kev xaiv cov khoom.
