摘　　要：采用机械合金化和冷压微波烧结法制备了B4C-CeB6/Al复合材料,通过X-射线分析和SEM扫描电镜分析B4C-CeB6/Al复合材料显微组织和相组成,并测定材料的硬度,研究了Al添加量对B4C-CeB6/Al复合材料组织的演变规律。结果表明:B4C-CeB6/Al复合材料粉体在球磨过程中发生机械合金化,粉体组织呈柱状;B4C-CeB6/Al复合材料的相组成随Al添加量变化,主要相有B4C、CeB6、Al2O3、Al3BC、Al5BO9和CeBO3;随Al添加量的提高,Al5BO9和CeBO3含量增加;CeB6和Al3BC先增加后减小,同时材料硬度也是先增大后减小。The B4C-CeB6/Al composites were prepared by mechanical alloying and cold-pressure microwave sin‐tering.The microstructure and phase composition of the B4C-CeB6/Al composites were analyzed by using x-ray dif‐fractometer and scanning electron microscope.The hardness of the materials was measured.The microstructure evolution law of the B4C-CeB6/Al composite was studied by the addition amount of Al.The results show that the B4C-CeB6/Al composite powders are mechanically alloyed during ball milling,and the powders are columnar.The phase composition of the B4C-CeB6/Al composites varies with Al addition,and the main phases are B4C,CeB6,Al2O3,Al3BC,Al5BO9 and CeBO3.With the increase of Al addition,the content of Al5BO9 and CeBO3 increases.The CeB6 and Al3BC phase increase first and then decrease,and the hardness of the material increases first and then decreases.
