Zoo heev - qhov kub thiab txias tsis kam (cov ntsiab lus zoo)
Lub ntsiab kom zoo dua ntawm TA15 yog nyob rau hauv nws zoo heev high -kub kev ua tau zoo, uas yog nws tshwj xeeb tshaj plaws feature distinguishes nws los ntawm Gr5 (TC4) thiab Gr9 (TA18). A 6.5% txhuas cov ntsiab lus muab cov khoom muaj zog -cov tshuaj tiv thaiv kom muaj zog. Lub 2% zirconium ntxiv txhim khu lub alloy qhov siab - qhov kub thiab txias zog los ntawm cov khoom siv ntxiv zog. Qhov sib ntxiv ntawm 1% molybdenum thiab 1% vanadium, nyob rau hauv qhov tsim nyog, txhim kho cov hlau tsis muaj zog thiab thermal stability thaum tswj kev ruaj ntseg ntawm nws nyob ze - microstructure. TA15 tuav lub zog tensile siab thiab nkag siab ntawm 500 degree, nrog rau lub sijhawm ua haujlwm ntev tshaj li ntawm Gr5 (400 degree) thiab Gr9 (350 degree). Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau siab - qhov kub thiab txias Cheebtsam hauv cov tshuab dav hlau.
Kev ruaj ntseg zoo heev
TA15 yog ze rau - titanium alloy. Vim tias qhov qis ntxiv ntawm molybdenum thiab vanadium (kwv yees li 1% txhua), nws muaj cov theem me me, uas ua rau muaj kev ruaj ntseg microstructural zoo nyob rau lub sijhawm ntev - kev pabcuam hauv qab 550 degree, tsis muaj qhov tseem ceeb coarsening ntawm theem lossis decomposition ntawm theem. Cov cuab yeej no zoo dua li ntawm + titanium alloys (xws li Gr5), ua rau kev ua haujlwm qeeb qeeb thiab kev ruaj ntseg zoo nyob rau hauv siab - kub ntev - cov kev pab cuam lub sij hawm. Nws yog vim li no tsim nyog rau cov khoom siv hauv aerospace uas yuav tsum tau ua kom ntev ntev - lub sij hawm cia siab rau thiab kwv yees lub neej ntev.
Kev ua haujlwm vuam zoo
TA15 muaj kev ua haujlwm zoo vuam. Tsis muaj kev ua kom sov ua ntej lossis tom qab- vuam cov cua sov yuav tsum tau ua thaum vuam, thiab cov khoom ntawm cov vuam sib txuas zoo ib yam li cov khoom siv hauv paus. Nws tuaj yeem txuas nrog ntau txoj hauv kev xws li TIG (Tungsten Inert Gas) vuam, plasma vuam, electron beam vuam, thiab laser vuam. Thaum lub sij hawm vuam, cov roj inert (argon) yuav tsum tau siv kom txaus los tiv thaiv qhov kub ntawm - kub oxidation paug.
Zoo corrosion kuj
Like all titanium alloys, TA15 relies on a dense, stable, and self-healing TiO₂ oxide film that forms spontaneously on its surface, exhibiting excellent corrosion resistance in atmospheric environments, seawater, chloride solutions, and most acidic media. Nws cov kev tiv thaiv corrosion yog piv rau Gr5, ua rau nws tsim nyog rau kev siv xws li marine ib puag ncig thiab tshuaj lom neeg.
Cov khoom kub ua haujlwm zoo
TA15 muaj cov khoom kub ua haujlwm zoo thiab tuaj yeem tsim los ntawm cov txheej txheem ua haujlwm kub xws li forging, kub dov, thiab kub extrusion nyob rau hauv qhov kub ntawm 900-1050 degree. Annealing tuaj yeem ua tau tom qab ua haujlwm kub kom ua tiav qhov kev pom zoo ua ke ntawm microstructure thiab cov khoom siv kho tshuab.
Kev ua tau zoo qaug zog thiab tawg toughness
Ua kom pom kev qaug zog zoo heev thiab kev ua kom tawg, tshwj xeeb tshaj yog nyob rau hauv bimodal thiab pob tawb -weave microstructures. Nws lub siab -kev ua haujlwm qaug zog thiab qaug zog tawg kev loj hlob tsis zoo yog qhov zoo tshaj rau cov nyob ze -alpha titanium alloys. Los ntawm kev tswj hwm microstructure, qhov sib npaug ntawm qhov sib npaug ntawm lub zog, plasticity, thiab tawg toughness tuaj yeem ua tiav, ua tau raws li kev tsim kev puas tsuaj rau kev tsim qauv rau cov khoom siv hauv aerospace.
