reported that Al has high stacking fault energy and the dislocations tend to dynamically recover due to the dominating wavy slip mode in the hot working above the recrystallization temperature of Al......
the movement of the dislocations, as a result, increased the strength of solders. In contrast, the high amount addition of Bi (5 wt.%) formed a large number of Bi precipitates in solder matrix......
but not from dislocations, i.e. σ0 is the flow stress of an undeformed single crystal orientated for multiple slip or approximately the yield stress of a very coarse-grained, untextured polycrystal......
)→β The formation of clusters or cluster 1 and cluster 2 depends on interaction of solute with the dislocations and vacancy inside the matrix. In RTR, only cluster was formed due to less dislocation... the formation of shear bands as shown in Fig. 13. The sub grain formation in CR was high due to the suppression of dislocation movement, which accumulated large number of dislocations in coarse grain......
occupy the preferential grain boundaries and behave as a geometrically necessary dislocation (GND). At the time of composite failure, the dislocations motion in the matrix is restricted by the GND... corrosion resistance, this bridging effect significantly contributes to the load sharing during loading, and consequently, enhances the composite performance. Figure 13(d) also shows the dislocations......

. Microstructure observations by HRTEM combined with image simulations allow to deduce the interfacial orientation relationships, lattice mismatch, and even misfit dislocations in an intuitive way. However......
of dislocations agglomeration surrounding Y2O3 particle in tensile test specimen of EPM Ti-46.6A1-1.4Mn-2Mo-0.3C-0.33Y alloy[45] 李宝辉[46]的研究表明,Y的添加可以明显提高TiAl合金的室温拉伸强度和伸长率,但是合金的室温拉伸强度和伸长率并非随Y含量的增加而一直提高,而是呈抛......
]. The interaction between AlN and dislocations enhances the wear resistance of the composite. Figure 4 depicts the SEM micrographs of worn surfaces of AA6061 alloy and AA6061/20%AlNp composite at sliding......
