Beta Titanium Alloy
Beta titanium alloys are high-elastic titanium alloys with a body-centered cubic lattice that, when quenched, produce a metastable structure for extreme cold forming. They offer high strength and endurance at high temperatures.
Physical-chemical mechanism of action
Beta titanium alloys have a body-centered cubic lattice that is made metastable by quenching. This leads to increased strength and endurance under high temperatures.
Metallurgical relevance & risks in welding
These alloys are particularly important in manufacturing components for aerospace and medical technology. Incorrect welding parameters can lead to deformation issues or a reduction of the metastable phase, which affects strength.
Workshop practice & action instructions
When welding beta titanium alloys, use high temperature and low voltage. The weld should be cooled slowly to preserve the metastable phase. Avoid rapid cooling, as this can lead to deformation.
