Nanoporous amorphous silicon (a-Si) with <5 nm cylindrical pores have been fabricated by phase separation of aluminum (Al) and silicon, forming self-assembled Al nanowires (NWs), followed by subsequent removal of Al by wet etching. This work studies the removal process of the Al NWs when using the...

Many important properties in the Al-Mg-Si alloy system, like hardness and toughness, is to a large extent determined by the atomistic precipitate interface structure. In this work we investigate the strain field around bulk hardening β'' precipitates and the fracture decohesion at β' grain boundary...
