What is beta titanium made of?

Up until recently, the most common Alpha-Beta phase titanium alloy has been Ti-6Al-4V, also known as Grade 5. This particular alloy, in addition to titanium, is comprised of 6% aluminum, 4% vanadium, and trace amounts of the element, iron.

What is beta phase titanium?

Beta titanium alloys are obtained when a high amount of β-stabilizer elements are added to the titanium, which decreases the temperature of the allotropic transformation (α/β transition) of titanium.

What is the composition of titanium?

Titanium alloys typically contain traces of aluminum, molybdenum, vanadium, niobium, tantalum, zirconium, manganese, iron, chromium, cobalt, nickel, and copper. The four grades, or varieties of titanium alloys are Ti 6AL-4V, Ti 6AL ELI, Ti 3Al 2.5 and Ti 5Al-2.5Sn.

What are α α β and β titanium alloys?

The alloys of titanium can be classified into three main groups as follows: Alpha alloys- These are non-heat treatable and are generally very weldable. Beta alloys- Beta or near beta alloys are readily heat treatable, generally weldable, and offer high strength up to intermediate temperature levels.

What are the elements that make up beta titanium?

Beta titanium alloys exhibit the BCC allotropic form of titanium (called beta). Elements used in this alloy are one or more of the following other than titanium in varying amounts. These are molybdenum, vanadium, niobium, tantalum, zirconium, manganese, iron, chromium, cobalt, nickel, and copper .

Which is better alpha or beta titanium alloys?

The beta alloys are readily heat treatable, with increased hardenability compared with alpha or alpha-beta alloys. Though the room temperature strength of this alloy is high, its high temperature strength is poor. Excellent formability can be expected of the beta alloys in the solution-treated condition.

Why is molybdenum added to beta titanium alloys?

The addition of molybdenum acts to stabilize the BCC (Body Centered Cubic) (beta) phase at room temperature; thus these alloys are referred to as beta titanium alloys. These beta titanium alloys promise 20% lower moduli, which are closer to bone and thus provide better formability with maintenance of other mechanical properties typical of Ti-6-4.

What does Beta C stand for in titanium?

Titanium Beta C refers to Ti Beta-C, a trademark for an alloy of titanium originally filed by RTI International.
