Dynamic recrystallization of copper polycrystals with different purities

Mechanical Properties of Fine-Grained Magnesium Alloys Processed by Severe Plastic Forging

“…The continuous increase in misorientations between (sub)grain boundaries evolved during deformation is an essential feature of cDRX, and the kinetics can be discussed by using the relationship between the average (sub)grain boundary misorientation (θ AV ) and total accumulated strain . The θ AV -ε relationships for Al alloy 2219 ECAPed at 523 K (Mazurina et al, 2008), a pure Cu MDFed at 195 K to 473 K (Gao et al, 1999, Belyakov et al, 2001, Kobayashi et al, 2007 and Mg alloy AZ31 compressed at 673 K are represented in Fig. 8.…”

Dynamic Recrystallization of Austenitic Stainless Steel under Multiple Peak Flow Behaviours

“…However, a transition from single peak to multiple peak behaviour has been reported under certain deformation conditions (very low strain rate and high temperature) and/or initial microstructures (small grain sizes). [1][2][3] Despite several studies of DRX in austenite exhibiting multiple peaks, 2,[4][5][6][7][8][9][10][11] many details remain unclear. The critical conditions for transition from single to multiple peaks, the microstructural development and also grain size evaluation under multiple peaks behaviour, are examples of issues that have not been completely resolved.…”

Approaches to Modeling of Recrystallization

“…The complexity of the nucleation process often requires some simplifications to be made during modeling of the event. It is therefore common to see for example grain boundary serration, relative grain boundary motion (shearing and sliding) and twinning mechanisms be disregarded although being vital parts in the nucleation process [24][25][26]. Experimental studies have also indicated that the character of the nucleation process changes with temperature and rate of deformation which complicates the picture [27].…”
