Single-phase interdiffusion in B2-RuAl intermetallic compound

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

“…Hence, pore effects which contribute to the measured interdiffusivity are not dominating. Further details of the diffusion experiments can be found in [8].…”

“…Consequently, recently published interdiffusion data concerning B2-RuAl are the first step towards a quantitative understanding of diffusioncontrolled processes [8]. It was found, that the temperature dependence of the interdiffusion coefficient D RuAl could be described by an Arrhenius law with an activation energy (Q) 236 AE 18 kJ mol À1 and a pre-exponential factor (D 0 ) (2.2 AE 1.6) Â 10 À6 m 2 s À1 .…”

“…The purpose of the present study is the analysis of composition as well as grain size effects on the interdiffusional data of RuAl as published in [8].…”

“…First investigations on the interdiffusion behavior in singlephase RuAl were performed by Woll et al [88]. Between 1473 K and 1773 K, only a single diffusion mechanism occurred.…”
