Lo lus "lub zog tshwj xeeb" yog hais txog qhov sib piv ntawm cov khoom siv lub zog rau nws qhov ntom, uas yog qhov zoo tshaj plaws ntawm titanium alloys. Titanium alloys muaj qhov ceev ntawm kwv yees li 4.51 g / cm³, tsuas yog 50% -60% ntawm 45 # steel, tab sis lawv lub zog yog piv rau 45 # steel, thiab qee qhov siab - lub zog titanium alloys txawm tshaj lub zog ntawm ntau cov hlau alloy steel. Hauv lwm lo lus, lub zog tshwj xeeb ntawm titanium alloys yog ntau dua li lwm cov khoom siv hlau, yog 2.2 npaug ntawm cov qauv hlau zoo tib yam. Vim tias qhov zoo heev "lub zog- rau qhov hnyav piv," titanium alloy screws feem ntau siv rau hauv daim ntawv thov uas yuav tsum tau muaj zog thiab hnyav kev tsim kho. Piv txwv li, titanium alloys yog indispensable nyob rau hauv lub aircraft engine Cheebtsam, thav duab, tawv, fasteners, thiab tsaws iav. Nyob rau hauv dynamic load scenarios xws li automotive suspensions thiab aircraft engine, upgraded GR5 titanium alloy screws yuav ua tau ib tug tensile zog txog li 1100 MPa thaum tuav ib tug elongation ntawm 8% -10%, deb tshaj qhov ua tau zoo ntawm cov tsoos stainless hlau.
Los ntawm cov khoom xaav, titanium alloys yog cov alloys uas muaj titanium ua lub hauv paus thiab lwm yam ntxiv. Tam sim no, muaj ntau dua 70 hom, suav nrog titanium-aluminium alloys thiab titanium- tooj liab alloys. These materials can form a dense oxide film on their surface, which not only provides corrosion resistance but also maintains good ductility and toughness in extreme environments ranging from -196℃to 600℃. Noj cov uas nquag sivGR5 titanium alloy ntsia hlauRaws li qhov piv txwv, tom qab kev kho kev daws teeb meem thiab kev laus, nws lub zog tensile tuaj yeem ncav cuag tshaj 1100MPa, thiab nws lub zog shear tuaj yeem ncav cuag tshaj 670MPa, ua tau raws li qhov xav tau ntawm siab - lub zog ua haujlwm.
