“…X alloy specimen #6, EDS data showed small amounts of Mn and impurity Fe elements besides the aluminum matrix (Figure 10 and Table 4). Several studies have pointed out the Fe element as an impurity element in aluminum alloys [11,[25][26][27]42]. High amounts of Fe and Mn elements in aluminum alloy could yield coarse and insoluble intermetallic compounds, such as Al 4 (Mn, Fe) Al 20 Mn 3 Cu 2 Al 3 Fe, which can easily form.…”

“…Under the action of cyclic stresses, the microcracks continued to propagate and connect to form cracks. Also, the propagation of long cracks would eventually lead to material fracture [42], thereby decreasing the fatigue strength of structural parts. Moreover, the inclusions in the aluminum alloy usually existed as blocks, needles, and sheets, seriously damaging the continuity of the alloy matrix (Figures 3-5).…”

In the present paper, the high cycle fatigue (HCF) of a novel 211Z.X aluminum alloy with high strength was studied under hot-rolling and as-cast states at room temperature. The effects of microstructure and distribution of precipitated phases and impurities on the mechanical properties, HCF performances, fatigue microcrack initiation, and propagation behavior of the 211Z.X alloy were studied by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). The HCF S–N curves, P–S–N curves and Goodman fatigue diagrams of 211Z.X alloy consisting of two microstructures were drawn. The results suggested that the fine and dispersive distribution of the second phases improved the strength of the alloy. The formation of short-bar and spherical precipitates promoted coordinated deformation of the alloy. This promoted higher microcrack initiation resistance of 211Z.X alloy with a hot rolling state than in the cast state. As a result, the HCF properties of the hot-rolling alloy were better than those of the cast alloy. In sum, these results look promising for future reliable design of engineering structures and application of new aluminum alloys.
