Abstract
One of the key strategies to enhance the performance of composites is the implementation of a lamellar structure, which has demonstrated remarkable success. In this study, an ultrathin lamellar WCu composite was fabricated using a combination of freeze-casting and infiltration techniques. Compared to the homogeneous WCu composite, the aligned structure in this composite provides continuous conductive channels for electrons, reducing interface scattering. Additionally, the ultrathin lamellae offer exceptional load-bearing capacity. These synergistic effects result in both superior strength and enhanced electrical conductivity. This innovative design strategy for WCu composites presents promising potential for advancing the development of next-generation composite materials.
期刊介绍：
The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
