Effects of composition and grain size on the interdiffusional behaviour in B2-RuAl intermetallic compound

First-principles study on B2 based XAl(X = Rh, Ru)compounds

“…Ru-Al compounds have attracted great attention as a promising material for high-temperature application due to physical, chemical, and mechanical properties [7][8][9][10][11]. The B2phase RuAl compound, one of the Ru-Al compounds, has been extensively studied in recent years [12,13]. Previous studies have reported that RuAl with B2-phase exhibits excellent oxidation and corrosion resistance at temperatures above 1473 K, as well as high melting point, high-temperature resistance, and thermodynamic stability [14,15].…”

Tailoring barrier layers design for haute couture through X-ray microanalysis: Insights and guidelines

“…As grain boundary diffusion was verified to be the predominant diffusion mechanism in the examined temperature range and considering that the grain boundary diameter is a determinant factor for E act 12 , then the dependency between E act and crystallite size can be explained by a decrease of boundary widths [ 36 ] as crystallites of a smaller size are closely packed [ 37 , 38 ], making it more energy-intensive for the diffusing species to pass through the them [ 10 ]. Also for electrodeposited metals a good agreement has been reported between the crystallite and grain sizes [ 39 , 40 ].…”

RuAl 2 : Structure, electronic and elastic properties from first-principles

“…Among all these Ru-Al compounds, B2-phase RuAl compound has been widely investigated over the last years [7,8]. Earlier works have reported that B2-phase RuAl not only shows high melting point, high-temperature strength and thermodynamic stability but also exhibits excellent oxidation and corrosion resistances when temperature above 1473 K [9,10].…”
