Daim ntawv thov ntawm Gr7 Titanium Alloy Casting
Apr 11, 2024
Gr7 titanium alloy casting yog hais txog titanium alloys siv rau casting rau hauv qee yam duab castings. Feem ntau deformed titanium alloys muaj zoo casting zog. Ib qho ntawm feem ntau siv yog Ti-6A1-4V alloy. Nws muaj qhov zoo tshaj plaws casting txheej txheem kev ua tau zoo thiab lub koom haum ruaj khov, thiab muaj lub zog zoo (5 σb Ntau dua lossis sib npaug ntawm 890MPa) thiab tawg toughness hauv qab 350 degree.
Kev khiav hauj lwm kub ntawm cam khwb cia titanium alloy feem ntau yog 300-400 degree . Feem ntau siv lub tshuab nqus tsev condensing plhaub rauv thiab graphite hom melting casting txoj kev. Feem ntau yog siv rau casting aero-engine magazine, txhawb sorghum, qhia cov hniav thiab lwm yam tsis-rotating qhov chaw, kuj yuav siv tau rau casting impellers thiab lwm yam rotating qhov chaw.
