Titanium Alloy Mechanical Properties
Titaniyamu aloyi ali ndi mphamvu mkulu ndi otsika kachulukidwe, zabwino makina katundu, kulimba bwino ndi kukana dzimbiri. Komanso, titaniyamu aloyi ndondomeko ntchito ndi osauka, kudula kovuta, mu processing otentha, zosavuta kuyamwa haidrojeni mpweya nayitrogeni mpweya ndi zosafunika zina. Pali kusamva bwino kukana, zovuta kupanga njira. Industrial kupanga titaniyamu anayamba mu 1948. Kukula kwa makampani ndege amafuna, kuti titaniyamu makampani ndi avareji pachaka kukula kwa 8% chitukuko.
Pakali pano, kutulutsa kwapachaka kwa titaniyamu aloyi pokonza zinthu padziko lapansi kwafika matani oposa 40,000, ndi mitundu pafupifupi 30 ya titaniyamu aloyi. Ma aloyi a titaniyamu omwe amagwiritsidwa ntchito kwambiri ndi Ti-6Al-4V(TC4), Ti-5Al-2.5Sn(TA7) ndi titaniyamu yoyera ya mafakitale (TA1, TA2 ndi TA3).
Ma aloyi a Titaniyamu amagwiritsidwa ntchito kwambiri popanga magawo a kompresa a injini za ndege, kutsatiridwa ndi zida zamaroketi, zoponya ndi ndege zothamanga kwambiri. Pofika chapakati pa zaka za m’ma 1960, titaniyamu ndi ma aloyi ake anali atagwiritsidwa ntchito m’mafakitale ambiri kupanga maelekitirodi opangira ma electrolysis, ma condenser a malo opangira magetsi, ma heaters oyeretsera mafuta ndi kuchotsa mchere, ndi zipangizo zowongolera kuipitsidwa. Titaniyamu ndi ma aloyi ake akhala ngati dzimbiri - zosagwira zida zomangira. Kuphatikiza apo, imagwiritsidwanso ntchito popanga zida zosungira ma hydrogen ndi ma alloys amakumbukidwe.
China idayamba kufufuza za titaniyamu ndi titaniyamu mu 1956; Pakati pa zaka za m'ma 1960, kupanga mafakitale a titaniyamu ndi chitukuko cha alloy TB2 chinayamba. Titanium alloy ndi chinthu chatsopano chofunikira chomwe chimagwiritsidwa ntchito m'makampani azamlengalenga. Mphamvu yake yokoka, mphamvu ndi kutentha kwa ntchito zili pakati pa aluminiyamu ndi chitsulo, koma mphamvu zake zenizeni ndizokwera ndipo zimakhala ndi dzimbiri zotsutsana ndi madzi a m'nyanja komanso kutentha kwambiri.
Mu 1950, F-84 womenya-bomber idagwiritsidwa ntchito koyamba ngati chishango chakumbuyo cha kutentha kwa fuselage, hood ya air, tail hood, ndi zida zina zosanyamula. Kuyambira m'ma 1960, kugwiritsa ntchito aloyi ya titaniyamu kwasunthidwa kuchokera ku fuselage yakumbuyo kupita ku fuselage yapakati, pang'onopang'ono m'malo mwa chitsulo chopanga kupanga zinthu zofunika kwambiri monga chimango, mtengo ndi flap slide. Kugwiritsiridwa ntchito kwa titaniyamu mu ndege zankhondo kwakula mofulumira, kufika pa 20% ~ 25% ya kulemera kwa ndege.
