Correlation of hardness and silicon morphology for al-si-sb alloy
Uzun, Orhan; Yılmaz, Fikret; Emeksiz, Cem; Ergen, Semra; Köleman, Uğur (Archives of Metallurgy and Materials, 2018)In this study, we have focused on the role of silicon morphology on the hardness of eutectic Al – 12 wt.% Si – 0.5 wt.% Sb alloy solidified at different cooling rates. The alloys were produced by using induction melting, ... -
Effect of Bismuth on hydrogen storage properties of melt-spun LaNi4.7-x Al0.3Bix (x = 0.0, 0.1, 0.2, 0.3) ribbons
Yılmaz, Fikret; Ergen, Semra; Hong, Soon-Jik; Uzun, Orhan (International Journal of Hydrogen Energy, 2018-11-01)The LaNi5 intermetallic compound is an AB5 type hydrogen storage alloy which exhibits low operating temperature, easy activation, low pressure and tolerance to impurities. In this study, LaNi4.7-x Al0.3Bix (x = 0.0, 0.1, ...
