Q1: Dab tsi yog qhov sib txawv ntawm C350 (L0) thiab C450 (L0) hauv AS1163, thiab cov neeg tsim qauv xaiv tau ntawm lawv li cas?

Lub zog txawv:

C350(L0)muaj aYam tsawg kawg nkaus paib zog (RH) ntawm 350 MPA, thaumC450(L0)lav tau ntau duaYam tsawg kawg nkaus los lub zog ntawm 450 MPA.

TusLub zog tensile (RM)ntawm C450 (L0) tseem yog feem ntau ntau dua (500-630 mpa vs {}}}}}}}}} (l0).

Cov Qauv Xaiv Rau Cov Tsim:

Cov ntawv siab dua:Yog tias tus qauv yuav tsum tau load ntau dua {{C450(L0)yog qhov zoo tshaj rau kev txuag hluav taws xob thiab cov khoom siv ua tau zoo.

Tus nqi vs. Performance:C350 (L0) feem ntau muaj kev lag luam ntau dua thiab txaus rau nruab nrab {2} Cov ntaub ntawv thov muab (piv txwv li, lub teeb {{5} {{5}

Ductility & formability:C350 (L0) yuav muaj kev formability me ntsis (khoov, vuam) vim nws lub zog qis, uas tuaj yeem muaj txiaj ntsig zoo nyob hauv Fabriccic.
