*3.1.1 Quasi-static tests*

Quasi-static tests are performed to failure, under the three deformation rates previously specified (0.001, 0.01, and 0.1 s<sup>−</sup><sup>1</sup> ). **Figure 6** shows stress-strain curves obtained for each strain rate applied, while **Table 1** summarizes the post-processed results. The results obtained show that material's peak stress remains constant under quasi-static regime with an average value of 532.603 MPa; this is based on the low value of the standard deviation (std. dev.) and the coefficient of variation (CV). The same

trend is observed for the Young's modulus obtaining an average value of 43.859 GPa. On the other hand, the strain at peak stress shows an average of 1.284% with a variation coefficient of 22.45%, which indicates that it varies considerably; however, it does not show a sensitivity on the strain rate or a correlation with a variation in the failure modes observed by fractographic observation, which indicates that dispersion in the measurements can be attributed to intrinsic errors in the measurement method. Having this in mind, it can be concluded that the mechanical behavior of the material is not strain rate sensitive within the strain rate range tested in the quasi-static regime.
