DOI: 10.1002/adem.201900988
Abstract: Columnar‐structured thermal barrier coatings (TBCs) manufactured by electron beam‐physical vapor deposition (EB‐PVD) are well known to exhibit high strain tolerance. However, as EB‐PVD is a high‐vacuum process, it is expensive. Suspension plasma spraying (SPS) and… read more here.

DOI: 10.1016/j.actamat.2017.02.025
Abstract: Abstract Additively manufactured (AM) metals are often highly textured, containing large columnar grains that initiate epitaxially under steep temperature gradients and rapid solidification conditions. These unique microstructures partially account for the massive property disparity existing… read more here.
