A series of deposition experiments using CoCrMo were performed using an Optomec LENS® machine. An analysis of hardness, microstructure, and wear trends of the deposited alloys was undertaken in an attempt to determine the applicability of using LENS® to create better materials for orthopedic implants. It was found that LENS®-deposited CoCrMo alloys were harder than wrought materials, however in...

Additive manufacturing (AM) of metallic alloys for structural and functional applications has attracted significant interest in the last two decades as it brings a step change philosophy design manufacturing. The ability to fabricate complex geometries not amenable conventional manufacturing, potential reduce component weight without compromising performance, is particularly attractive aerospac...

In this study, refill friction stir spot welding (RFSSW) was used to join AlSi10Mg, produced by laser powder bed fusion (LPBF), high-strength wrought AA7075-T6 alloy. The investigation showed the best mechanical properties and integrity of joint are achieved with medium heat input, where optimal balance between hook height observed. welded additive manufactured alloy shows accentuated softening...

It remains challenging to achieve attractive mechanical strength and ductility in commercial 7xxx alloys fabricated by wire-arc additive manufacturing (WAAM). Here, we combine WAAM processing with solution artificial aging treatments functionalise their inherent age-hardening capabilities via microstructure controlling. The as-deposit 7055 alloy shows a heterogeneous bimodal grain size distribu...
