Abstract:  
High strength metals such as titamium, zirconium, various steels and 7075 aluminum, have been widely used where high strength to weight ratios are required, particularly in aerospace structures. Unfortunately, many of these materials can crack unexpectedly when infiltrated by hydrogen. The cause of these failures of often a mystery because the crack inducing hydrogen can dissipate into the atmosphere before it is identified.
