“…As can be seen, the fit of the experimental data to the prediction obtained from the models is reasonably good, given the simplicity assumed in these two models. Other factors, such as stress relaxation by diffusion [73] [74,76], whereas the load transfer mechanisms, however, are common to all these materials and under different conditions. In summary, it is possible to study, in great detail, the specific damage mechanisms occurring during composite deformation, but it is very difficult to predict which mechanism will operate and its importance before the test is conducted.…”

“…The drop of hardness at higher temperature (0.9 T m ) is again due to DRX. At higher temperatures when 7075 alloy is deformed with a large value of strains DRX occurs above 0.8 T m which is a reported fact [18][19][20].…”

“…This fact explain s the greater (D d /D f ) observed in the composites at the highest test temperature, and the limited localization of particle fracture in notched specimens. P revious studies [5,27] revealed a clear correlation between damage evolution and the achievable material strength. The delayed onset of material damage on the maximum net stress is also clearly visible in notched specimens, particularly at high temperature, where both forms of microstructural damage reduced and notch strengthening was observed in most cases.…”
