Abstract

Ultra-refractory Hf₄ZrC₅–(Hf,Zr)B₂ composites were prepared by electrothermal explosion (ETE) under pressure in a one-stage process, with special emphasis on the influence of high-energy ball milling (HEBM) of starting Hf–Zr–C–B powder mixtures. Synthesized Hf₄ZrC₅–(Hf,Zr)B₂ composites had a grain size of 0.5–1.0 μm and a porosity of 10–12%.

加压电热爆炸制备超难熔Hf 4 ZrC 5 –（Hf，Zr）B 2复合材料

摘要

超高压Hf ₄ ZrC ₅ –（Hf，Zr）B ₂复合材料是在一个阶段的过程中通过电热爆炸（ETE）在压力下制备的，其中特别强调了高能球磨（HEBM）的影响Hf-Zr-C-B粉末混合物。合成的Hf ₄ ZrC _5-（Hf，Zr）B ₂复合材料的晶粒尺寸为0.5-1.0μm，孔隙率为10-12％。
