TA7 Titanium Alloy: Kev Ntsuam Xyuas Luv Luv Ntawm Cov Khoom Thiab Cov Khoom Siv

1, TA7 thiab TA7ELI alloys yog hom alpha-hom alloys. Cov nominal muaj pes tsawg leeg yog Ti-5Al-2.5Sn. aluminium thiab tin ua lub luag haujlwm hauv stabilizing thiab kev daws teeb meem ntxiv dag zog.

2, TA7 alloy tsis tuaj yeem ua kom sov-kho kom muaj zog, tsuas yog los ntawm recrystallization annealing kom ua tiav -theem tshuaj ntxiv dag zog. Recrystallization pib kub ntawm 580 degree. - theem hloov pauv ntawm 1020 ~ 1030 degree; recrystallization annealing kub, phaj 700 ~ 750 degree; bar, forgings 800 ~ 850 degree; Kev ntxhov siab nyem annealing kub ntawm 550 ~ 600 degree.

3, TA7 alloy muaj lub zog nruab nrab, nkag siab thiab thermal stability kuj zoo. Lub sijhawm ua haujlwm ntev tuaj yeem ncav cuag 450 degree, thiab lub sijhawm ua haujlwm luv luv tuaj yeem ncav cuag 800 ~ 850 degree.

4, TA7 alloy muaj qhov ua tau zoo ntawm qhov kub thiab txias. Raws li qhov kub thiab txias, lub zog nce thiab plasticity txo me ntsis. TA7ELI alloy muaj cov ntsiab lus qis ntawm cov khoom sib txuas thiab tseem tuav cov yas zoo ntawm -250 degree, feem ntau yog siv rau cov thawv ntim khoom kub thiab lub zog siab, thiab feem ntau yog muab los ua cov phaj thiab tuav.

5, TA7 alloy txheej txheem plasticity yog tsawg, phaj stamping yuav tsum tau nqa tawm nyob rau hauv ib tug rhuab lub xeev, feem ntau rhuab mus rau 700 degree. Thiab muaj cov txheej txheem shaping txaus.
