Hafnium-Zirconium Carbonitride (Hf,Zr)(C,N) by One Step Mechanically Induced Self-Sustaining Reaction: Powder Synthesis and Spark Plasma Sintering
نویسندگان
چکیده
Nanostructured single-phase hafnium-zirconium carbonitride powders were synthesized using a simple and fast mechanochemical synthesis approach. The critical milling duration, after which (Hf,Zr)(C,N) solid solution formation inside jar occurred via mechanically induced self-sustained reaction (MSR), was 10 min. After 30 min of treatment, solid-gas completed, as result, homogeneous powder consisting 10–500 nm submicron particles obtained. phase structure evolution the different treatment durations allowed for establishment possible mechanisms, included Hf/Zr/C-layered composite particles, their interaction MSR, further grinding nitridization. Spark plasma sintering (SPS) used to produce bulk ceramics from nanostructured powder. sample had higher values relative density, hardness, fracture toughness than those binary compounds similar composition.

Spark-plasma-sintering (SPS) of nanostructured titanium carbonitride powders
Spark-Plasma-Sintering (SPS) compaction experiments of nanostructured titanium carbonitride powders have been performed at 1600°C and 1800°C (sintering time = 1 min). The as-received nanostructured samples have been synthesized by rapid condensation from the gas-phase (high frequency plasma). The sintering results were compared with data obtained by various conventional sintering techniques suc...

متن کاملSpark Plasma Sintering of Ultra-High Temperature Tantalum/Hafnium Carbides Composite
TaC and HfC are thought to have the highest melting point (~4000°C) among all refractory materials. The binary solid solution of TaC and HfC (Ta4HfC5) is also considered as the most refractory material with the melting point over 4000 °C and valuable physical and mechanical properties. The main goal of this work is to fabricate TaC/HfCbased composites which consolidated by means of spark plasma...
