摘要：

为了研究烧结助剂Y₃Al₅O₁₂对热压烧结制备的B₄C陶瓷的影响,以B₄C微粉为原料,以Al₂O₃+Y₂O₃原位反应生成的Y₃Al₅O₁₂为烧结助剂,在1950℃烧结温度下,采用热压烧结工艺制备出B₄C陶瓷,研究Y₃Al₅O₁₂添加量对B₄C陶瓷物相组成、烧结性能、微观结构和力学性能的影响。研究结果表明:当烧结助剂Y₃Al₅O₁₂添加量<7wt.%时,B₄C陶瓷中晶界以B₄C-B₄C晶粒相连接的清洁晶界和B₄C-非晶相Y₃Al₅O₁₂-B₄C晶界2种形式存在;当烧结助剂Y₃Al₅O₁₂添加量≥7wt.%时,B₄C陶瓷中晶界以B₄C-B₄C晶粒相连接的清洁晶界、B₄C-非晶相Y₃Al₅O₁₂-B₄C晶界和B₄C-晶相Y₃Al₅O₁₂-B₄C晶界3种形式存在;当Y₃Al₅O₁₂添加量为7wt.%时,热压烧结B₄C陶瓷的综合性能最佳,即相对密度为96.2%,硬度为20.9GPa,抗弯强度为455MPa,断裂韧性为3.53MPa·m^1/2;烧结助剂Y₃Al₅O₁₂通过改变热压烧结B₄C陶瓷的气孔率、晶粒尺寸和晶界特征影响B₄C陶瓷的力学性能。

Abstract:

To investigate the effect of Y₃Al₅O₁₂ sintering additive on B₄C ceramics prepared by hot-press sintering,B₄C ceramics are prepared using B₄C powders as the raw material and Y₃Al₅O₁₂ generated from the in-situ reaction between Al₂O₃ and Y₂O₃ as the sintering additive by hot-press sintering process at the sintering temperature of 1950℃.The effects of different contents of Y₃Al₅O₁₂ sintering additive on the phase composition,sintering properties,microstructure,and mechanical properties of B₄C ceramics are studied.The results show that the grain boundaries in the B₄C ceramics exist in two forms of B₄C-B₄C clean grain boundaries and B₄C-amorphous Y₃Al₅O₁₂-B₄C grain boundaries when the content of Y₃Al₅O₁₂ sintering additive is less than 7 wt.%,and the grain boundaries in the B₄C ceramics exist in three forms of B₄C-B₄C clean grain boundaries,B₄C-amorphous Y₃Al₅O₁₂-B₄C grain boundaries and B₄C-crystallised Y₃Al₅O₁₂-B₄C grain boundaries when the content of Y₃Al₅O₁₂ sintering additive is more than or equal to 7wt.%.When the content of Y₃Al₅O₁₂ sintering additive is 7wt.%,the best properties of B₄C ceramics are achieved by hot-press sintering.The relative density,Vickers hardness,bending strength,and fracture toughness of B₄C ceramics are 96.2%,20.9GPa,455MPa,and 3.53MPa·m^1/2,respectively.The Y₃Al₅O₁₂ sintering additive affects the mechanical properties of B₄C ceramics prepared by hot press sintering by altering their porosity,grain size,and grain boundary characteristics.
