摘要：

Tungsten-based composites often exhibit good performance for high temperature applications, such as high strength, however, the very limited plasticity at room temperature becomes an intrinsic “Achilles’ heel” due to the incompatible strain partition between different phases. In this work, an equiatomic CoCrNi medium-entropy alloy (MEA) was used as a novel binder to fabricate W–CoCrNi composites through laser metal deposition (LMD) technique. The microstructural features and corresponding mechanical properties were systematically investigat...
