Hauv kev txiav cov teb xws li aerospace, kev cog tshuaj kho mob, gr1ium {however however {} Txawm li cas los xij, tsis pub dhau los ua neeg muaj zog, muaj kev lag luam ntshiab GR5) Ua kom pom kev ua yeeb yam sib txawv ntawm cov tshuaj muaj kuab lom, cov khoom siv lub cev, thiab cov ntawv thov kev siv ua {}}
Los ntawm cov qauv sib txawv raws li Astm cov qauv (TA1 (GR1) nrog rau lub tensile ntau dua 900 mpa, peb zaug ntawm TA1 (GR1)), thiab faib daim ntawv thov Cov xwm txheej (TA1) DEEV cov tshuaj chemical thaum tc4 (Gr5) kav lub rooscraCers "nyob rau hauv Titanium cov ntaub ntawv sib txawv ntawm cov khoom siv science thiab engineering.
Kab lus no yuav, raws li cov qauv xws li ASTM B265 / F1472, pab koj xaiv qhov kev xaiv ntawm ob qho kev xaiv nrog phiaj xwm kev xav.

TA1 (GR1) (Industrial ntshiab Titanium)
Lub ntsiab Cheebtsam: Titanium (TI) cov ntsiab lus ntau dua los yog sib npaug ntawm Immurities (xws li hlau, carbon, oxygen, etc.).
Tsis muaj lwm yam alloying ntsiab, ze rau ntshiab titanium .
TC4 (GRR5) (TI -6 Al -4 v)
Cov Cheebtsam Tseem Ceeb: Titanium (ti) raws li lub hauv paus, nrog 6% aluminium (al) thiab 4% vanadium (v) ntxiv.
Nws yog ib + dual-theem titanium alloy, nrog kev txhim kho kev ua tau zoo los ntawm alloying .

Qhov sib txawv:
TA1 (GR1): Zoo me ntsis hauv kev txo cov kua qaub (xws li hydrochloric acid) dua tc4 (gr5) (thiab tsis muaj kev pheej hmoo ntawm al / v cais) .
TC4 (GRR5): Tsib Hlis ua cov yeeb yaj kiab tiv thaiv vim ib puag ncig kub ntawm qhov chaw muaj kev ntxhov siab ntau dua, tab sis muaj me ntsis qib siab corrosion.
