Cov yam ntxwv thiab kev siv

BT22 titanium alloy bar muaj cov yam ntxwv xws li lub zog siab, siab toughness, thiab zoo hardenability. Nws yog ze rau - hom titanium alloy nrog kev ua tau zoo tag nrho. Cov khoom zoo ntawm BT22 titanium alloy, suav nrog siab -kub tsis kam, corrosion kuj, thiab lub zog siab, tau txais kev nyiam dav hauv kev lag luam xws li aerospace.

Nrog rau txoj kev loj hlob sai ntawm Tuam Tshoj cov ntaub ntawv aerospace teb, cov kev ua tau zoo ntawm aerospace structural Cheebtsam tau dhau los ua nruj heev. Tshwj xeeb, kev txhim kho kev ua haujlwm ruaj khov ntawm titanium alloy cov ntaub ntawv nyob rau hauv siab - qhov kub thiab txias ib puag ncig yog qhov ua tiav rau kev txhim kho aerospace technology. BT22 titanium alloy bars feem ntau yog siv rau hauv cov dav hlau loj forgings, tswj tshuab, tsaws iav, thiab siab -load- bearing aerospace structural Cheebtsam, thiab lawv tau dav siv nyob rau hauv aircraft xws li Lavxias teb sab Il-76.

Khoom Paub meej

Cov ingots siv rau kev tsim BT22 titanium alloy bar thiab forgings yog melted siv lub tshuab nqus tsev tus kheej -consumable arc rauv. Tus naj npawb ntawm melting cycles yuav tsum tsis txhob tsawg tshaj li peb, thiab thaum lub sij hawm kawg ruaj khov theem ntawm lub xeem melting, lub siab yuav tsum tsis txhob ntau tshaj 5 Pa (tsis suav melting nrog inert gas ntxiv).

Qib, mob, thiab specifications ntawm BT22 titanium alloy tuav yog qhia nyob rau hauv Table 3.
