Secondary recrystallization in Fe–6.5 wt% Si alloys by internal friction

Mechanical spectroscopy in Fe–Al–Si alloys at elevated temperatures

“…On the other side, a grain boundary peak in this temperature range has also been proposed in Fe-Al alloys [22]. (3) In Fe-10 at.% Si alloy obtained by the single rolled method, it was found out that the peak height decreases after recrystallization [11]. This reduction in the peak height is related to the reduction of the effective free grain boundaries fraction owing to the crystalline grain growth [11,28], which is typical in the GB relaxation.…”

“…The present results are discussed on the basis of the grain boundary migration controlled by the order degree of the structure. These results are relevant due to the close relation between order degree, mobility of defects and magnetic quality in iron based alloys [11,13,14].…”

“…Additionally, a study of the grain boundary (GB) relaxation in binary Fe-Si alloys has been reported in Refs. [10][11][12]. In these works, the behaviour of the characteristic grain boundary relaxation in iron and the grain boundary peak related to the presence of solute atoms in the iron matrix [4] was studied in order to correlate the behaviour of these peaks to the recrystallization and order degree.…”

Dislocation Movement in WE43 Magnesium Alloy during Recovery and Recrystallisation

“…In contrast, at temperatures higher than those for the grain boundary relaxation, the mobility of grain boundaries and dislocations is larger and then recrystallisation takes place. 26,[34][35][36][37] This temperature (700 K) is similar to the recovery temperature deduced from the 1% deformed samples at 300 K. Results show that the line of the distinction between recovery and recrystallisation is sometimes difficult to define, because recovery plays an important role in nucleating recrystallisation. 36,37) Nevertheless, it is interesting to point out that the recovery and the recrystallisation are generally considered as two different phenomena.…”

“…Therefore, we can relate this behaviour to a recrystallisation process, in agreement with previous reported works. [33][34][35] In fact, the strong increase in the modulus after heating run #8 can be explained by the appearance of internal stresses due to the growth of newly oriented strain-free grains. This process starts when the damping peak during heating run #8 develops, i.e.…”
