Managing mechanical and electrical properties of nanostructured Cu-Fe composite by aging treatment

Y. Z. Tian et al.

Summary: In this study, nanostructured Cu-10Fe composites were prepared by heavy cold rolling, and the microstructure evolution and properties of the composites during aging were systematically studied. It was found that the strength and ductility of the composites changed monotonically with increasing aging temperature, while the electrical conductivity initially increased and then decreased. The mechanisms for the superior mechanical and electrical properties were discussed by quantifying the contributions of different microstructural constituents.

Anisotropic mechanical and corrosion properties of directionally solidified Mg-3Zn-0.2Ca alloy

Yi Zhang et al.

Summary: The Mg-3Zn-0.2Ca alloy fabricated by directional solidification exhibited highly anisotropic mechanical and corrosion properties. The anisotropy in mechanical properties was attributed to the activation of different deformation mechanisms, while the anisotropic elastic modulus was due to the difference in atomic bonding strengths at different crystallographic planes. Additionally, the corrosion resistance of the alloy also showed anisotropy, with the specimen taken along LD direction showing superior resistance.

Preparation and properties of W-30 wt% Cu alloy with the additions of Ni and Fe elements

He Zhang et al.

Summary: This study successfully prepared high-performance W-Cu-Ni-Fe alloys with the addition of Ni and Fe using low temperature liquid-phase sintering. The additions of Ni and Fe improved the bonding strength and wettability of the alloy, resulting in enhanced mechanical properties. Moreover, the Ni and Fe additions also increased the compressive strength and solid solution strengthening effects of the alloy. However, it led to a decrease in the electrical conductivity.

Effect of spark plasma sintering temperature on structure and performance characteristics of Cu-20wt%W composite

Xiuqing Li et al.

Summary: This study investigates the effect of spark plasma sintering temperature on the structure and performance characteristics of Cu-W composite. The optimal SPS sintering temperature for Cu-20 wt%W composite is found to be 950 degrees C. Increasing the sintering temperature leads to an increase in copper-liquid content, which can facilitate the rearrangement of tungsten particles and improve the performance of the composite. However, excessively high temperatures result in inhomogeneous distribution of tungsten and copper phases and a decline in composite performance.
