Titanium Alloy Steel Plate

Titaniyamu alloy ndi aloyi wopangidwa ndi titaniyamu monga maziko ndi zinthu zina anawonjezera.Titaniyamu ili ndi mitundu iwiri ya makhiristo amtundu umodzi komanso wosiyanasiyana: mawonekedwe odzaza ndi ma hexagonal omwe ali pansi pa 882 ℃ α Titaniyamu, thupi lokhala ndi kiyubiki pamwamba pa 882 ℃ β Titanium.

Zinthu za alloy zitha kugawidwa m'magulu atatu kutengera mphamvu yawo pakusintha kutentha kwa gawo:

① Stable α Zinthu zomwe zimawonjezera kutentha kwa gawo ndi α Zinthu zokhazikika zimaphatikizapo aluminiyamu, carbon, oxygen, ndi nitrogen.Aluminiyamu ndiye gawo lalikulu la aloyi wa titaniyamu, lomwe limakhudza kwambiri kutentha kwa chipinda ndi kutentha kwamphamvu kwa aloyi, kuchepetsa mphamvu yokoka, ndikuwonjezera zotanuka modulus.

② Chokhazikika β Zinthu zomwe zimachepetsa kutentha kwa gawo ndi β Zinthu zokhazikika zimatha kugawidwa m'mitundu iwiri: isomorphic ndi eutectoid.Zogulitsa zomwe zimagwiritsa ntchito titaniyamu aloyi Yoyamba imaphatikizapo molybdenum, niobium, vanadium, ndi zina;Zomalizazi zikuphatikizapo chromium, manganese, mkuwa, chitsulo, silicon, etc.

③ Zinthu zosalowerera ndale monga zirconium ndi malata zimakhala ndi zotsatira zochepa pa kutentha kwa gawoli.Oxygen, nitrogen, carbon, and hydrogen ndizo zonyansa zazikulu muzitsulo za titaniyamu.Oxygen ndi nayitrogeni mu α Pali kusungunuka kwakukulu mu gawoli, komwe kumalimbitsa kwambiri ma alloys a titaniyamu, koma kumachepetsa pulasitiki.Mpweya wa oxygen ndi nayitrogeni mu titaniyamu nthawi zambiri umatchulidwa kuti ukhale pansi pa 0.15 ~ 0.2% ndi 0.04 ~ 0.05%, motsatira.Hydrogen mu α Kusungunuka mu gawoli kumakhala kochepa kwambiri, ndipo hydrogen yambiri yomwe imasungunuka mu titaniyamu alloys ikhoza kutulutsa ma hydrides, kupanga alloy brittle.Mafuta a haidrojeni mu titaniyamu aloyi nthawi zambiri amayendetsedwa pansi pa 0.015%.Kusungunuka kwa haidrojeni mu titaniyamu kumasinthidwa ndipo kumatha kuchotsedwa ndi vacuum annealing.
