Abstract
Metal foam materials are used for various purposes including electrode materials, catalyst filters, and gas diffusion filters due to their porous structure. Increasing demand for metal foams has generated research to increase porosity as well as produce different pore sizes. The present paper illustrates a comparison of open-cell aluminum foams...

Korean J. Met. Mater. 2017;55(6):396-404.   Published online 2017 Jun 1
DOI: https://doi.org/10.3365/KJMM.2017.55.6.396

Abstract
The influence of ultrasonic melt treatment (UST) combined with a change in cooling rates on the microstructure and elevated temperature mechanical properties of a hypereutectic Al-18Si-4Cu-3Ni piston alloy was investigated. Microstructural observation confirmed that UST effectively refined the sizes of primary Si and intermetallic compounds (e.g. ε-Al3Ni) while promoting their..... More

Korean J. Met. Mater. 2017;55(4):240-246.   Published online 2017 Apr 6
DOI: https://doi.org/10.3365/KJMM.2017.55.4.240

Abstract
The effect of ultrasonic melt treatment (UST) on the microstructure and mechanical properties of Al-7Si-0.35Mg (A356) casting alloys was investigated. The particular aim of this study was to analyze the mechanism involved in the strengthening of the A356 alloys when fabricated by UST. The UST had little effect on the..... More
