添加剂Nb和烧结温度对ZrN粉末材料性能的影响
|
摘要
在ZrN粉末中添加Nb粉,经热压烧结得到Nb-ZrN粉末材料,研究添加剂Nb与烧结温度对Nb-ZrN材料烧结和力学性能的影响。结果表明:提高烧结温度有利于加快材料的致密化,Nb-ZrN1480粉末出现了1个致密化速率峰,其它粉末材料还生成了另外2个小的致密化速率峰,烧结Nb-ZrN1680粉末的相对密度达到98.6%。各粉末材料的X射线衍射谱图中都存在ZrO_2衍射峰,添加剂Nb在烧结阶段全部溶入ZrN内。添加Nb后,ZrN晶格常数减小,随烧结温度上升,ZrN晶格常数基本保持稳定。纯ZrN材料表现为沿晶断裂,添加Nb后,粉末材料发生穿晶断裂,气孔数明显降低。
The Nb-ZrN powder materials were prepared by hot pressing sintering, adding Nb powders as the additive in ZrN matrix. Effects of additive Nb and sintering temperature on the sintering and mechanical properties of ZrN powder materials were researched. The results show that, the increase of sintering temperature benefits the material densification, a densification rate peak is present in Nb-ZrN1480 powder materials, and two other small rate peak appear in other Nb-ZrN powder materials. The relative density of Nb-ZrN1680 powders after sintering can achieve as high as 98.6%. The diffraction peak of ZrO_2 is found in X-ray diffraction spectra of all Nb-ZrN powders, the additive Nb dissolves into the ZrN matrix in sintering stage. After adding Nb as the additive, the ZrN lattice constant reduces and then remains stable with the increase of sintering temperature. Pure ZrN shows the intergranular fracture, the Nb-ZrN powder materials exhibit the transgranular fracture, and the number of pore is decreased obviously.
