“…FSP also increases the density of dislocations in the SZ most of which have been annihilated during dynamic recrystallisation [34]. However, based on the previous findings, in addition to the dislocation networks along the sub-grain boundaries [34], considerable amounts of dislocations have remained in the SZ grains [35,36] whose interaction can improve the SZ strength through dislocation strengthening mechanism [28]. Increasing the number of FSP passes (i.e.…”

“…As a result, the refinement and more uniform distribution of these compounds in the matrix, similar to what is seen in Figure 3, can reduce the amplitude of the accumulated stress which in turn improve their resistance against fracture and/or de-bonding. In addition, the finely dispersed particles can more effectively impede the movement of dislocations, and their reduced interspacing significantly increases the stress required for dislocations motion [28,29]. Decreasing the grain size, and consequently, increasing the density of grain boundaries can also play a significant role in the overall mechanical properties improvement of coatings.…”

“…Nevertheless, it exhibits remarkable mechanical properties at elevated temperatures (up to 500 °C) owing to the existence of a thermally enduring intermetallic phase composed of Al 3 Ni (with a melting point of 854 °C) [12][13][14].…”

“…Al-Ni eutectic alloys exhibit excellent fluidity, excellent feedability, and low susceptibility to hot tearing [8]. However, it exhibits high mechanical properties at high temperatures thanks to its thermally stable Al3Ni intermetallic phase [9]- [11]. It is stated that in Al-Ni alloys, depending on sample processing and annealing conditions, the first phase to be formed will be Al3Ni [12]- [14], AlNi [15] or Al9Ni2 [11], [14], [16].…”

Zuogui Zhang et al [2], in their study on the corrosion behavior of Al-5.4%Ni (wt) alloy, it was stated that preferential corrosion pits were formed in the Al phase area and that the more homogeneous and thinner Al/Al3Ni structure played a vital role in improving the corrosion resistance of the alloy.…”
