Momwe mungasankhire mbale ya titaniyamu

Zinthu za alloying zitha kugawidwa m'magulu atatu malinga ndi mphamvu zawo pakusintha kutentha kwa gawo:

1.Zinthu zomwe zimakhazikitsa gawo la α ndikuwonjezera kutentha kwa kusintha kwa gawo ndi α zinthu zokhazikika, monga aluminium, carbon, oxygen, ndi nitrogen. Pakati pawo, aluminiyamu ndiye chinthu chachikulu cha aloyi cha titaniyamu, chomwe chimakhala ndi zotsatira zoonekeratu pakuwongolera kutentha kwabwino kwa aloyi ndi kutentha kwakukulu, kuchepetsa mphamvu yokoka, ndikuwonjezera zotanuka modulus.

2. Chinthu chomwe chimakhazikitsa gawo la β ndikuchepetsa kutentha kwa kusintha kwa gawo ndi β-stabilizing element, yomwe ingagawidwe m'mitundu iwiri: isomorphic ndi eutectoid. Zopangidwa pogwiritsa ntchito titaniyamu aloyi monga molybdenum, niobium, ndi vanadium; Zomalizazi ndi chromium, manganese, mkuwa, chitsulo, ndi silicon.

3. Zinthu zomwe sizimakhudza pang'ono kutentha kwa kusintha kwa gawo ndi zinthu zopanda ndale, monga Zr, Sn, etc.

Oxygen, nayitrogeni, carbon ndi haidrojeni ndizo zonyansa zazikulu muzitsulo za titaniyamu. Oxygen ndi nayitrogeni ali ndi kusungunuka kwakukulu mu gawo la α, lomwe limalimbitsa kwambiri titaniyamu alloy, koma limachepetsa pulasitiki. Nthawi zambiri zimanenedwa kuti mpweya ndi nayitrogeni zomwe zili mu titaniyamu ziyenera kukhala pansi pa 0.15-0.2% ndi 0.04-0.05% motsatana. Kusungunuka kwa haidrojeni mu gawo la α ndikochepa kwambiri, ndipo hydrogen yambiri yomwe imasungunuka mu titaniyamu alloy idzatulutsa ma hydrides, zomwe zimapangitsa kuti alloy awonongeke. Nthawi zambiri, hydrogen zomwe zili mu titaniyamu aloyi zimayendetsedwa pansi pa 0.015%. Kusungunuka kwa haidrojeni mu titaniyamu kumasinthidwa ndipo kumatha kuchotsedwa ndi vacuum annealing.
