GR1, GR2, GR3, GR4 Titanium yog dab tsi?
GR1 titanium hlau, GR2, GR3, thiab GR4 yog unalloyed (ntshiab) titanium.GR1 titanium yeeb nkabthiabGR2 titanium yeeb nkabraug cais raws li kev lag luam qib ntshiab.
Cov yam ntxwv ntawm titanium: lub teeb yuag thiab siab corrosion kuj.GR1 titanium tubeyog siv rau hauv kev lag luam chemical, kev pabcuam dej hiav txwv, marine structures, thiab biomedical cov ntaub ntawv.
Piv nrog rau hlau, titanium muaj qhov sib nqus me me tab sis muaj zog dua, muab lub zog siab - rau - qhov hnyav piv. Txawm li cas los xij, vim tias qhov tshwj xeeb lub ntiajteb txawj nqus me me (qhov muaj peev xwm thermal me me),GR1 titanium yeeb nkabheats tau yooj yim thiab txias sai sai.
Qhov txawv ntawm GR1, GR2, GR3, thiab GR4 yog dab tsi?
Qhov txawv ntawmTi-Qib 1, GR2, GR3, thiab GR4 tsuas yog nyob rau hauv cov ntsiab lus ntawm Oxygen (O), Hlau (Fe), thiab Nitrogen (N). Mechanical zog xws liGR1 titanium yield zog, tensile lub zog, thiab elongation nce los yog txo nrog nce los yog txo ntawm cov ntsiab lus no.Qib 1 titanium hardnessyog qhov qis tshaj ntawm plaub qib vim nws cov ntsiab lus oxygen tsawg.
Tseem ceeb:Oxygen nce hauv titanium nce brittleness. Thaum cov pa oxygen ntxiv dag zog rau theem alpha, nws kuj txo qis elongation, toughness, thiab siab - kub stability.GR1 titanium tshuaj muaj pes tsawg leegnrog 0.15-0.18% oxygen siab tshaj plaws muab qhov zoo tshaj plaws ductility rau kev ua haujlwm.
Qhov sib txawv ntawm cov ntshiab titanium GR1 thiab GR2: Titanium CP1muaj oxygen tsawg (0.15% max) tshaj GR2 (0.20% max), muabGR1 titanium hlausiab dua ductility thiab qis zog. RauGR1 titanium rau kev kos duab sib sib zog nqusdaim ntawv thov, Qib 1 yog nyiam dua Qib 2.Titanium qib 1 vs qib 2kev xaiv yuav tsum yog nyob ntawm seb qhov formability (GR1) los yog me ntsis siab zog (GR2) yog qhov tseem ceeb.GR1 titanium txoj kev / dabtsi yog khoovmuaj peev xwm ua tau zoo dua rau GR2 vim yog cov ntsiab lus oxygen tsawg.
