Two different microstructural architectures featuring multiple length scales have been created in the thermoelectric Mg2(SixSn1 x) system. The first one combines the nano-grain microstructure, characteristic of rapid solidification, with a large-scale pseudo-periodic pattern in one direction. The second is a layered structure in which the composition and microstructural scale vary from layer to...

Ti5Si3 is an attractive light weight reinforcement phase in hypereutectic Ti–Si-based alloys, however, the proeutectic Ti5Si3 phase is brittle and is easily coarsened when the alloy is prepared under normal solidification conditions, thereby limiting its engineering applications in the aviation and biological industries. In this study, a hypereutectic Ti–20%Si coating with a pseudo-eutectic α-T...

We show that a granular suspension, composed of particles immersed in a liquid, can form pearls, hooks, and arches when deposited from a nozzle onto a translating substrate that acts as a liquid super-absorber. The removal of the liquid induces a rapid pinning of the contact line leading to mechanically stable structures that are held together by capillary adhesion with shapes that depend on th...
