Gaseous hydrogen embrittlement of 3D-printed Inconel 718 manufactured from sustainable feedstock

Laser powder bed fusion (L-PBF) is an additive manufacturing (AM) technology that has been gaining a lot of interest as it allows to produce parts with complex geometries and eliminate expensive tooling. Unlike the conventional manufacturing processes where material is removed to make the final component; AM part is manufactured layer-wise as...

Effect of Heat Treatment on Microstructure and Mechanical Behavior of Additively Manufactured Nitinol Shape Memory Alloys

Nitinol shape memory alloys (SMAs) have a unique combination of shape memory capability, making it an attractive material for various engineering and biomedical applications. Additive manufacturing (AM) by laser powder bed fusion (L-PBF) allows to produce Nitinol net shape parts, which broadens its applications. Due to the high heating and...

Damage Tolerant Design for Additive Manufacturing: An experimental study on the fatigue behaviour of stretch dominated AlSi10Mg multiple load path specimens

To expand the use of additive manufacturing in aerospace towards more critical applications, it is required to design parts in a damage tolerant context. Therefore, the damage tolerance of additive manufactured multiple load path structures is assessed by analysing the fatigue life and damage propagation of components with increasing redundancy....
