Ultrahigh-temperature high-entropy carbide ceramic-based composite material, in-situ preparation method and application
The invention belongs to the field of high-entropy ceramics and high-temperature-resistant materials, and particularly relates to an ultrahigh-temperature high-entropy carbide ceramic-based composite material, an in-situ preparation method and application. The chemical formula of the ultrahigh-temperature high-entropy carbide ceramic-based composite material is (NbaMobTacWdMeDf) Cg, M is one or more of Ti, Zr, Hf and other metal elements, and D is a metalloid element. According to the high-entropy carbide-based composite material, high-entropy carbide ceramic serves as a base body, high-entropy alloy is distributed between the ceramic base bodies, the reinforcing and toughening effects are achieved, and the structure of the high-entropy carbide-based composite material can be regulated and controlled by changing the C content. The process is simple, the cost is low, the preparation period is shorter, the prepared composite material is high in density and purity and has more excellent room-temperature and high-temperature performance, the room-temperature strength is not lower than 3500 MPa, and the strength at the temperature of 2000 DEG C is not lower than 400 MPa.
本发明属于高熵陶瓷和耐高温材料领域，具体涉及一种超高温高熵碳化物陶瓷基复合材料、原位制备方法及应用。该超高温高熵碳化物陶瓷基复合材料，化学式为(NbaMobTacWdMeDf)Cg，其中M为Ti，Zr，Hf等金属元素的一种或几种，D为类金属元素。该高熵碳化物基复合材料以高熵碳化物陶瓷为基体，高熵合金分布于陶瓷基体之间，达到增强增韧的效果，并可通过改变C含量调控其组织。本发明工艺简单，成本低，制备周期更短，且制备出的复合材料致密度和纯度高，具有更优异的室温和高温性能，室温强度不低于3500MPa，2000℃时的强度不低于400MPa。
