The hydrogen economy is forecasted to grow significantly. The infrastructure required to support its emergence means more materials will contact high pressure hydrogen as it is created, stored, transported, and used as a fuel. Seals, gaskets, and non-metallic pipelines are prime examples of polymers that hydrogen will readily encounter along its life cycle. Hydrogen is...

Inconel 718 components produced using additive manufacturing (AM) generally require heat treatment to form strengthening precipitates and optimize the phase fractions of all precipitates. Work done at EWI has been focused on developing a heat treatment procedure specifically for AM-generated IN718 parts. The results of this research are discussed in Optimization of the Post Heat...

Compromised “kissing bonds” in solid-state welds are tough to identify with conventional ultrasonic testing. Recently, EWI investigated using the ultrasonic process known as full matrix capture/total focusing method (FMC/TFM) to detect kissing bonds in intentionally fabricated kissing bonds, and found that these weak welds could be positively identified. This promising research is discussed in Detection...
