Method for rapidly preparing fully-compact refractory metal carbide high-entropy ceramic
The invention discloses a method for rapidly preparing high-density refractory metal carbide high-entropy ceramic, and belongs to the technical field of high-entropy ceramic materials and powder metallurgy. According to the method, high-purity refractory metal carbide powder with small particle size difference is fully and evenly mixed under the argon atmosphere, the mixed powder is put into a graphite mold to be pre-pressed, then a pressed blank is put into a rapid hot pressing furnace in a high-vacuum environment, and through the process steps of high pressure, instantaneous high temperature, cooling and short-time heat and pressure preservation at low temperature, the high-purity refractory metal carbide powder is obtained. The refractory metal carbide high-entropy ceramic which is fully compact, small in grain size, single in phase and uniform in structure is prepared.
一种快速制备高致密性难熔金属碳化物高熵陶瓷的方法，属于高熵陶瓷材料和粉末冶金技术领域。本发明将高纯且颗粒尺寸差异较小的难熔金属碳化物粉末在氩气气氛下充分混合均匀，将混合粉末放入石墨模具中进行预压，再将压坯放入高真空环境的快速热压炉中，通过高压‑瞬时较高温‑降温‑较低温短时保温保压的工艺步骤，制备得到全致密、晶粒尺寸较小、单一物相、组织均匀的难熔金属碳化物高熵陶瓷。
