This paper delineates additive friction stir deposition, which offers a solid-state deformation processing route to metal additive manufacturing and renders fully-dense material with fine, equiaxed microstructures in the as-printed state.
A new twinning mechanism, transformation twinning, was discovered in a Ti–6Al–4V alloy fabricated by selective laser melting. The resulting high density of transformation twins impact the global mechanical properties significantly.
We report on the material design, synthesis, and observation of a superconducting transition at 8.0 K in new high-entropy-alloy type compound with a CuAltype structure, CoNiCuRhIrZr.
This paper reports that the Hall-Petch co-efficient (K) dramatically increase when Al is added to CoFeNi/CoCrFeNi alloys. Such a trend is attributed to the ordering mediated nano-clustering in Al containing HEA/CCAs.
Nano/ultrafine Fe grains containing Cu particles of 5 nm in size and 10 nm in spacing were achieved by SLM of Fe-Cu, resulting in an ultrahigh strength material.
