Beschreibung
Zusammenfassung:	The invention relates to a roll-bonded titanium sheet ( 6 ), a shaped component manufactured therefrom ( 10 ) and a method for manufacturing the titanium sheet ( 6 ) and the shaped component ( 10 ). In order to achieve a high-temperature-resistant shaped component ( 10 ), a titanium sheet ( 2 ) is roll-bonded at least on one side with aluminium foil ( 4 ) whose thickness (d) is small compared with the thickness (D) of the titanium sheet ( 2 ). As a result of heat treatment of the roll-bonded titanium sheet ( 6 ), the aluminium and titanium from the adjoining region are converted to an aluminium-titanium alloy. The outer titanium-aluminium-alloy layer of the titanium sheet ( 6 ) thus formed is converted by contact with oxygen into a titanium-aluminium-mixed oxide layer which gives the titanium sheet ( 6 ) good corrosion protection. The forming of the shaped component ( 10 ) preferably takes place before the heat treatment for alloy formation because the roll-bonded titanium sheet ( 6 ) is then still slightly deformable.
