The presence of hydrogen in titanium considerably alters the mechanical properties and ductility. Metallic materials can be hydrogen embrittled. To determine the quantity of Hydrogen in Reactive Metals and Reactive Metal Alloys, our laboratory refers to the ASTM E1447 test method.There are two main sources of hydrogen embrittlement in metals, particularly titanium :
In the first case, hydrogen is already present in the metal. Internal embrittlement occurs during the manufacturing process: casting, surface cleaning, pickling, electroplating, machining, welding or heat treatment.In the second case, embrittlement is external. Hydrogen is introduced during use, due to environmental factors such as corrosion or lack of protection of the metal or titanium alloys.
