Abstract

The gradient ceramic/metal composite of TiC-TiB₂/Al_0.3CoCrFeNi was prepared by combustion synthesis under ultra-high gravity field. Right after the formation of the mixture by combustion, the ceramics and metals are separated in an ultra-gravity field due to the difference in mass density, resulted in a gradient distribution of ceramics (TiC-TiB₂) along the gravitational field in the high-entropy alloy (Al_0.3CoCrFeNi) matrix. The hardness of the material shows a significant gradient change.
