Titanium Grade 2 Cold Formability
Titanium grade 2 cold formability is the ability of unalloyed titanium to be plastically deformed at room temperature without cracking. This requires low oxygen content.
Physical-Chemical Mechanism of Action
Titanium Grade 2 cold formability refers to the ability of unalloyed titanium to deform plastically at room temperature without cracking. This is possible when the titanium contains a low number of oxygen atoms. These atoms can cause splitter formation during the forming process, thus leading to cracks.
Metallurgical Relevance & Welding Risks
In titanium with too high oxygen content, cold formability can be severely limited. This leads to increased susceptibility to cracking and splitter formation during bending or deep drawing. Insufficient removal of oxygen can therefore result in poor-quality workpieces.
Workshop Practice & Instructions
To ensure Titanium Grade 2 cold formability, it is crucial to minimize the oxygen content of the titanium material before the forming process. This can be achieved by careful cleaning and using pure filler metal. When bending or deep drawing, the speed should be kept controlled to ensure uniform deformation. Recommended oxygen contents should be below 0.1%.
