The modified relaxation time function: A novel analysis technique for relaxation processes. Application to high-temperature molybdenum internal friction peaks

Order controlled dislocations and grain boundary mobility in Fe–Al–Cr alloys

“…5) seems to point out that more than one elemental process contributes to the peak [38]. In any case, considering a single relaxation the Arrhenius plot for the solute grain boundary peak in FeAlCr8 and FeAlCr25 are shown in Fig.…”

Study of the temperature evolution of defect agglomerates in neutron irradiated molybdenum single crystals

“…In contrast, by increasing the annealing temperature to 973 K (stage V), which is higher than the temperature for the maximum observed in the ER curves, the damping peak appears during the cooling without dependence on the amplitude of vibration. This behaviour was explained considering the movement of vacancies to the dislocations [15,23,24]. Besides this, it was also reported that the yield stress and the UTS also decreases with an increase of the annealing temperature at temperatures higher than about 973 K [8,16].…”

Interaction processes between vacancies and dislocations in molybdenum in the temperature range around 0.3 of the melting temperature

“…In addition, if the diffusion process is of type pipe diffusion, i.e. diffusion along the dislocation line, the activation energy, H d , is related to H sd through H d = a H sd , where a has values between 0.6 and 0.8, depending on the type of dislocation core [15,[34][35][36][37][38][39][40]. In molybdenum, the reported values for H vm and H vf are among 1.35 eV 6 H vm 6 1.60 eV [41,42] and 3.0 eV 6 H vf 6 3.2 eV [42,43], respectively, leading thereof to H sd between 4.35 and 4.8 eV.…”
