Vuam Ntawm Gr23 Titanium Alloy
Apr 13, 2024
Gr23 titanium alloy welded composite qauv tsis tsuas yog muaj titanium alloy siab tshwj xeeb lub zog thiab zoo corrosion kuj, tab sis kuj sib xws nrog qhov zoo ntawm cov ntaub ntawv steel nrog ntau yam kev siv thiab pheej yig tus nqi. Txawm li cas los xij, vim cov titanium alloy thiab steel thermal conductivity thiab coefficient ntawm linear expansion ntawm qhov sib txawv yog loj heev, thiab kev sib nrig sib solubility tsis zoo, vuam yog ib qho yooj yim los tsim nkig nyuaj Ti-Fe intermetallic tebchaw, ua rau titanium alloys / steel dissimilarity. vuam nyuaj.
Qhov sib txawv ntawm cov hlau vuam yog hais txog ob hom sib txawv thiab cov khoom ntawm cov khoom siv hlau los ntawm cov txheej txheem vuam tshwj xeeb los koom ua ke thiab tsim cov qauv tsim nrog kev ncaj ncees thiab kev ua tau zoo. Lub thermal conductivity thiab coefficient ntawm linear expansion ntawm titanium alloys thiab cov hlau tsis sib xws yog qhov sib txawv heev, thiab cov khoom sib txuas ntawm cov khoom sib txuas zoo li yuav raug tsim thaum lub sijhawm vuam, ua rau lub zog ntawm cov pob qij txha tsis zoo. Yog li ntawd, qhov sib ntxiv ntawm cov hlau hloov pauv tsim nyog nyob rau hauv cov txheej txheem vuam, kev xaiv cov txheej txheem vuam tsim nyog thiab cov txheej txheem vuam yog tsim nyog los txhim kho microstructure thiab txhua yam khoom ntawm welded pob qij txha.
