Effect of Ce addition on castability, mechanical properties and electric conductivity of Al–0.3Si–0.2Mg alloy

Conductive Al Alloys: The Contradiction between Strength and Electrical Conductivity

“…RE can compensate for the loss of conductivity caused by the increase in dislocation density. The researchers noted that when the amount of Ce addition reached 0.2 wt%, the EC of Al–Mg–Si alloys was significantly improved (from 52.1% IACS to 56.3% IACS), [ 49 ] which is similar to the result described in the ref. [50].…”

Effects of Ni Content and Alloying Elements on Electrical Conductivity, Mechanical Properties, and Hot Tearing Susceptibility of Al-Ni-Based Alloys

“…There are many factors affecting the HTS of an alloy, including freezing range [11], grain refinement [14,15], and eutectic fraction [11]. Generally, hot tearing resistance increases with increasing eutectic liquid fraction [11] and decreasing grain size [16]. In this study, the decrease of the HTS with Ni addition could be explained by the grain size reduction (as shown in Figure 1) and the increase in the area fraction of the Al 3 Ni eutectic phase (Figure 2).…”

Review on recent progress in Al–Mg–Si 6xxx conductor alloys

“…This is because Ce in combination with Fe and Si forms AlFeSiCe compounds. Therefore, a reduction in Fe and Si levels in the matrix led to a higher EC [ 67 ]. However, Si consumption and depletion in the matrix reduced the precipitation response and strength.…”

“…Aside from lanthanum elements, the effect of cerium on the properties of Al-Mg-Si conductors was also investigated [ 67 ]. It was found that the Ce addition (0.3 wt.%) resulted in an EC improvement.…”
