Surface modification of ceramic and metallic alloy substrates by laser raster-scanning
… powder precursor grown from polycrystalline Alloy 718 substrates. A heat transfer model was developed to illustrate that the aspect ratio of the laser scanned pattern and the density of scanning lines play a significant role in determining peak surface temperature, heating and cooling rates …

Entropy and surfaceness
… Specifically, Nitinol, a shape memory alloy, will be considered as 'dissipative media' in a dynamic building system. The proposed built system will then become a metallic alloy atmosphere on the thin surface boundary of a structure. Working also to dissipate an influx of solar energy, …
