Effect of ordering on grain boundary segregation
Lejček, Pavel ; Schneeweiss, Oldřich
A simple phenomenological model of solute segregation at partially ordered grain boundaries is proposed and used to correlate complex concentration and temperature dependences of silicon segregation in ordered Fe-Si alloys.
Fázové přechody v nanokrystalické slitině Zr-Fe indukované vodíkem
Roupcová, Pavla ; Schneeweiss, Oldřich ; Pizúrová, Naděžda ; Zhu, Min
Nanocrystalline composite based on Zr-Fe alloy is investigated. In the as-prepared powder composite ZrO2, Zr3FeH7, alpha-Fe, Fe2Zr and amorphous phases were recognized. During an annealing in vacuum crystalline and a few manner of amorphous phases transforms to ZrO2. The attempts to hydrogenate the same sample by annealing in hydrogen of the ambient pressure were successful at temperatures above - 673 K.
