Influence of Nanosized AlN Powders on the Microstructure, Brazeability, and Tensile Properties of Al-based Filler for Low Temperature Al/Cu Dissimilar Brazing
Do Hyun Jung, Jae Pil Jung
Korean J. Met. Mater. 2018;56(9):664-673.   Published online 2018 Sep 5
DOI: https://doi.org/10.3365/KJMM.2018.56.9.664

This study examined the influence of nanosized aluminum nitride (AlN) powders (0, 0.01, 0.05, 0.10, 0.30, and 0.50 wt%), on an Al4047-based filler metal. Nanosized AlN powders were dispersed uniformly into the filler metal by a mechanical mixing and melting route using a stainless steel propeller. The influences of nanosized..... More

Korean J. Met. Mater. 2017;55(12):870-879.   Published online 2017 Dec 4
DOI: https://doi.org/10.3365/KJMM.2017.55.12.870

The effects of Nb on grain refinement and the pitting corrosion resistance of Febalance18Cr10 Mn0.3C0.3NxNb (x = 0.1 and 0.2 wt%) high interstitial alloys were investigated through microstructure analysis and potentiodynamic polarization tests. The resistance to pitting corrosion of the two alloys, covered with a passive film and an air-formed..... More

Korean J. Met. Mater. 2017;55(8):537-543.   Published online 2017 Aug 1
DOI: https://doi.org/10.3365/KJMM.2017.55.8.537

To study the effect of Al and Zr contents on the microstructural changes and tensile properties of Ni-Al-Bronze alloy, seven specimens were cast with different Al and Zr contents. The microstructure observation revealed that all specimens were composed of β’ and κ phases in a α matrix. With increasing Al..... More
