【摘要】 本文采用JCXA—733型电子探针、二次电子图象（SEI）、背散射电子图象（BEI）、特征X射线及3014型X射线衍射仪,对Al₂O₃—TiC金属陶瓷材料中的Cr和W在Al₂O₃和TiC中的固溶强化作了分析。还研究了Al₂O₃和TiC两个连续网络骨架相互穿插强化的机理。本工作对研究试制新型优质金属陶瓷刀具材料有实际意义。更多还原

【Abstract】 This paper has analysized the solid solution strengthening of Cr and W in A1₂O₃ and TiC for A1₂O₃—TiC cermet by secondary electron image（SEI）, backscattered electron image （3EI） and generating X—rays with JCXA—733 type electron probe, X—ray micro—analyser and 3014 type X—ray diffraction unit. The streng thening mechanism of A1₂O₃ and TiC,two continuous mesh skeletons which penetrate into each other was also studild. The present work has practical significance for the trial-preduction of high quality cermet used for cutting tool materials.更多还原
