Lotus-type porous Mg–xMn (x= 0, 1, 2 and 3 wt.%) alloys were fabricated by metal/gas
eutectic unidirectional solidification (the Gasar process). The effects of Mn addition and the …

The study focuses on the aspect of using the structure of gasars, ie materials with directed
open porosity, as a potential hydrogen storage. The structure of the tested gasar is …

The 3D pore morphology of an optimized Gasar copper ingot was characterized using X-ray
tomography and the optimized Gasar copper ingot was fabricated by the Bridgman-type …

There is a wide range of processes to fabricate porous materials made of ceramics,
polymers, and metals with an extensive range of applications. The Gasar method is one of …

This paper presents a simple multisection unit-cell model (UCM) with which to investigate
the sound absorption characteristics of lotus-type porous metals (LTPMs). This model is …

Multi-step withdrawal schemes with varying speeds of Bridgman method were designed and
studied by numerical simulation and experimental methods in order to improve the pore …

Array holes were obtained by machining methods or nontraditional machining methods, and
casting process was rarely used in the preparation of array holes. In this experiment …
