Piv nrog rau lwm cov hlau hlau, titanium thiab titanium alloys hauv kev lag luam yog qhov phem dua, uas yog vim muaj ob yam, 1, titanium ua thiab cov teeb meem ntau lawm, ua rau titanium thiab titanium alloys hauv kev lag luam nrov ntawm lwm cov hlau qeeb, thiab rau ib qho twg cuam tshuam rau cov neeg siv khoom noj. 2, cov neeg siv tau siv cov ntaub ntawv alloy uas lawv tau siv ntau dua. Tab sis nrog kev loj hlob thiab kev ua tiav ntawm titanium thiab titanium alloy metallurgy nrog rau kev siv tshuab, ntau yam khoom zoo heev ntawm titanium tau maj mam nrhiav tau thiab siv, uas tau txhim kho cov koob npe ntawm titanium alloys rau qee qhov, yog li dab tsi yog cov khoom tshwj xeeb thiab qhov zoo ntawm titanium alloys, tshwj xeeb tshaj yog cov raj tshwj xeeb? Koj tuaj yeem xa mus rau cov ntsiab lus hauv qab no:
1, muaj zog tshwj xeeb. Lub zog tshwj xeeb yog hais txog qhov sib piv ntawm lub zog tensile thiab ntom, titanium raj tensile lub zog tuaj yeem ncav cuag 100-140kgf / mm2, thaum qhov ceev tsuas yog 60% ntawm lwm cov hlau.
2, kev ua haujlwm kub tsis zoo. Feem ntau hais lus, zoo li cov titanium alloy nrog cov ntsiab lus qis heev, xws li TA7, nws tuaj yeem tuav tau qee yam ntawm plasticity ntawm -253 degree , thiab lwm yam hlau tsis tuaj yeem ua tiav cov nyhuv no;
3, zoo corrosion kuj. Cov ntsiab lus no tau qhia ntau zaus ua ntej, qhov kev tiv thaiv corrosion ntawm titanium yog qhov zoo heev, qhov no yog vim tias nyob rau hauv cov huab cua, xws li titanium phaj, titanium raj, titanium bar thiab lwm yam khoom titanium, qhov saum npoo ntawm kev tsim ntawm ib txheej ntawm cov khoom sib xws. oxidized zaj duab xis, txheej txheej ntawm oxidized zaj duab xis no muaj kev tiv thaiv corrosion zoo heev. Tom qab ntau yam kev ntsuam xyuas, titanium muaj qhov zoo corrosion kuj nyob rau hauv ntau yam acids thiab alkalis, nyob rau hauv cov nqe lus ntawm corrosion kuj, titanium yog zoo dua li cov hlau stainless.
4, siab zog. Titanium nyob rau hauv mus txog rau 450-500 degree kub tseem tuaj yeem ua haujlwm ib txwm siv sijhawm ntev, uas yog lwm cov hlau tsis tuaj yeem ua, thiab kev siv cov titanium kub dua aluminium alloy ntau pua zaus siab dua.
Hauv cov ntsiab lus, nws tuaj yeem pom tias qhov kev ua tau zoo ntawm titanium tubing ua rau nws tshwj xeeb hauv ntau qhov chaw tshwj xeeb thiab lub sijhawm.
