TB9(Ti-38644) titanium alloy Ti--3Al-8V-6Cr-4Mo-4Zr

Titanium muaj ob hom homogeneous thiab heterogeneous crystals: titanium yog ib homogeneous isomer nrog lub melting point ntawm 1668 degree, thiab ib tug ntom kab ntawm hexagonal lattice qauv hu ua a-titanium ntawm qis dua 882 degree; thiab lub cev-centered cubic lattice qauv hu ua B-titanium ntawm 882 degree lossis siab dua. Kev siv titanium cov yam ntxwv sib txawv ntawm ob lub qauv saum toj no, ntxiv cov ntsiab lus alloying tsim nyog, kom lub sijhawm hloov pauv kub thiab cov ntsiab lus ntawm cov ntsiab lus maj mam hloov thiab tau txais cov koom haum sib txawv ntawm titanium alloys (titanium alloys).
Titanium alloys muab faib ua peb hom: (1) titanium alloy (2) titanium alloy (2) + titanium alloy. Ntawm lawv, -titanium alloy muaj qhov zoo tshaj plaws machinability, + -titanium alloy yog thib ob, -titanium alloy yog qhov phem tshaj. -titanium alloy yog coded li TA, -titanium alloy yog coded li TB, thiab + -titanium alloy yog coded li TC.

TB9 (Ti-38644) titanium alloy yog sub-stabilized coj mus muag titanium alloy tsim los ntawm RMI nyob rau hauv 1960s, nrog ib tug muaj pes tsawg leeg ntawm Ti-3Al-8V-6Cr{ {7}}Mo-4Zr, uas yog ib qho alloy uas muaj titanium ua lub hauv paus rau kev ntxiv lwm yam.
TB9 alloy muaj cov ntsiab lus loj ntawm -stabilizing cov ntsiab lus, thiab Mo cov ntsiab lus hauv cov hlau no yog qhov siab heev, ua rau muaj kev tiv thaiv corrosion zoo heev thiab tsis kam rau ntsev kev nyuaj siab corrosion thiab lwm yam khoom. Yog li ntawd nws yog amenable rau ntau yam kev kho cua sov, piv txwv li, cov alloy yog muab sib txawv zog-plasticity fits los ntawm kev hloov cov kev kho cua sov specification.
TB9 alloy muaj qhov zoo ntawm cov yas zoo, siab zog thiab elasticity, zoo hardenability, thiab nws cov hardened cross-section tuaj yeem ncav cuag 225mm. cov hlau tom qab kev kho laus kho kub lub zog tuaj yeem ncav cuag 1200 ~ 1400MPa, tawg toughness ntawm 58 ~ 66MPa.m% 2, muaj zog tensile siab thiab corrosion kuj, tuaj yeem siv los ua cov ntaub ntawv caij nplooj ntoos hlav, TB9 titanium alloy yog dav siv hauv aviation springs, High-strength TB9 titanium alloy yog dav siv nyob rau hauv aerospace springs, high-strength fasteners, torsion bar foil honeycomb qauv, aircraft carrier ejection ntaus ntawv thiab roj drilling thiab lwm yam teb.
