Dab tsi yog Titanium Alloy Bar?
Feem ntau, cov tuav thiab cov pob zeb ua los ntawm titanium thiab titanium alloy yog muab annealed raws li ASTM B348 lossis ASME SB-348. Qib 1, 2, 2H, 3, 4, 5, 6, 7, 7H, 9, 11, 12, 13, 14, 15, 16, 16H, 17, 18, 19, 20, 21, 23, 24, 25 , 26, 26H, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, thiab 38 yog tag nrho nrog rau hauv cov qauv specification. Cov hlau yuav tsum ua kom tiav ASTM B348's "Table 1 Chemical Requirements" thiab "Table 2 Tensile Requirements."
Titanium Alloy Bar: semifinished khoom seem khoom uas yog txias ua hauj lwm, kub dov, forged, extruded, los yog muaj ib tug ntoo khaub lig seem ntawm tsawg tshaj li 16 nti2 (10323 mm2); Qhov dav ntawm daim duab plaub yuav tsum tsis pub tshaj 10 nti (254 mm) thiab lub thickness yuav tsum tsis pub tshaj 0.1875 nti (4.8 mm). Extruded bar tsuas yog siv tau rau qib 1, 2, 3, thiab 4 ntawm cov titanium tsis siv. Cov qib sib txawv yuav raug tsim los ntawm kev tshem tawm lub voj voog raws li cov neeg yuav khoom thov.
Billet ntawm Titanium thiab Titanium Alloy: ib qho khoom ib nrab ua tiav los ntawm kev ua haujlwm kub los yog forging ib qho ingot, nrog qhov dav uas tsawg dua tsib npaug ntawm nws cov tuab thiab qhov chaw hla ntawm ntau tshaj 16 nti2 (10323 mm2).
TC1 titanium alloy, tseem hu ua Ti2Al1.5Mn, yog cov khoom siv muaj zog thiab lub teeb yuag uas belongs rau tsev neeg alpha-beta titanium alloy. Nws yog tsim los ntawm titanium (Ti), txhuas (Al), thiab manganese (Mn), nrog rau kwv yees li 2 feem pua Ti, 1.5 feem pua Al, thiab 0.5 feem pua Mn.
Titanium Alloy Bar yog ob-theem alpha-beta alloy, uas txhais tau hais tias nws muaj kev sib xyaw ntawm alpha thiab beta theem hauv nws cov microstructure. Lub alpha theem muab siab zog thiab toughness, thaum lub beta theem muab ductility thiab zoo formability. Qhov kev sib xyaw ua ke ntawm cov khoom no ua rau TC1 titanium alloy yog cov khoom siv zoo heev rau ntau yam kev lag luam uas yuav tsum tau muaj zog, tsis muaj zog, thiab zoo heev corrosion kuj.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm TC1 titanium bar yog nws lub zog-rau-qhov hnyav piv, uas ua rau Ti2Al1.5Mn titanium bar ua cov khoom siv zoo tshaj plaws rau kev siv aerospace thiab tsheb. Qhov tsawg ntom ntom ntawm titanium tso cai rau kev tsim cov khoom sib sib zog nqus uas tseem muaj zog thiab ua haujlwm ntev. Tsis tas li ntawd, 6al 4v titanium alloy bar muaj kev tiv thaiv zoo heev hauv dej hiav txwv thiab lwm qhov chaw hnyav, uas ua rau Titanium Alloy TC1 Bar haum rau kev siv dej hiav txwv thiab sab nrauv.

TC1 Titanium Weldability:
tsis muaj kev txwv: vuam yog ua tiav yam tsis muaj cua sov thiab kev kho cua sov tom qab
txwv weldability: vuam yog ua tau nyob rau hauv cua sov mus txog 100-120 qib thiab tom qab cua sov kho
hard weldability: tau txais cov vuam zoo xav tau kev ua haujlwm ntxiv: cua sov mus txog qib 200-300; kev kho cua sov ia annealing.
Cov ntaub ntawv thov
Ib daim ntawv thov ntawm TC1 titanium bar nyob rau hauv kev lag luam aerospace yog kev tsim cov khoom siv tsaws iav rau lub dav hlau. Kev tsaws iav yog ib qho tseem ceeb ntawm lub dav hlau uas yuav tsum muaj kev tiv thaiv siab thiab cuam tshuam thaum lub sij hawm ya tawm thiab tsaws. 6al 4v titanium alloy bar yog cov khoom siv zoo tshaj plaws rau cov ntawv thov no vim nws lub zog siab, tsis tshua muaj siab, thiab zoo heev corrosion kuj.
Ib qho piv txwv ntawm daim ntawv thov no yog kev tsaws iav rau lub dav hlau Boeing 777, uas yog tsim los ntawm TC1 titanium alloy. Kev tsaws iav muaj ntau yam, nrog rau lub ntsiab strut, sab strut, thiab luag strut. Cov khoom no yog tsim los ntawm TC1 titanium alloy vim nws lub zog siab-rau-hnyav piv, uas pab txo qhov hnyav ntawm cov iav tsaws thaum tuav nws lub zog thiab kav ntev.
Ntxiv nrog rau nws lub teeb yuag thiab lub zog siab, Titanium Alloy TC1 Bar kuj tseem muaj kev tiv thaiv zoo rau corrosion, uas yog ib qho tseem ceeb rau kev tsaws iav cov khoom uas raug rau ib puag ncig hnyav. Lub peev xwm ntawm TC1 titanium alloy los tiv thaiv corrosion hauv cov dej ntsev ib puag ncig ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsaws iav hauv kev siv dej hiav txwv xws li amphibious aircraft.
Zuag qhia tag nrho, kev siv Ti2Al1.5Mn titanium bar hauv kev tsaws iav cov khoom siv rau lub dav hlau yog qhov piv txwv zoo ntawm cov khoom siv no tuaj yeem muab lub zog siab, tsis muaj zog, thiab zoo heev corrosion kuj nyob rau hauv cov ntaub ntawv tseem ceeb uas muaj kev nyab xeeb thiab kev ntseeg siab yog qhov tseem ceeb.
