1. 新型极高熔点碳化物陶瓷的结构裁制与性能提升 

　　(1)遴选聚丙烯酸分散剂，揭示TaC粉体表面物理化学吸附机制，制备稳态悬浮的TaC水基浆料。与传统干压成型相比，注浆成型素坯的微结构更均匀。 

　　(2)首次实现(Ta,Hf)C固溶相陶瓷常压致密化，揭示高温原位固溶对(Ta,Hf)C极高熔点陶瓷近净尺寸致密化的贡献。针对第二相剪裁设计，实现(Ta,Hf)C基超高温常压烧结体综合性能连续可调。 

　　(3)通过理论模拟结合SPS制备实验验证，建立了Ta_1-xHf_xC_y体系的脆-延转变判据。 

　　2.新型SiC基复合材料高效可控制备 

　　采用EPD手段诱导SiC填料定向迁移并填充纤维束间大孔实现预致密化；联用EPD和PIP多种手段，获得强度和韧性同步提升的SiC基复合材料。
