硼化物自生复合材料的制备

PREPARATION OF BORIDE EUTECTIC IN-SITU COMPOSITE

    摘要
  • 摘要: 用电子束悬浮区熔法制备了LaB6-ZrB2共晶自生复合材料,其组织为LaB2基体上均匀分布着直径为0.2～1.1μm的ZrB2纤维.单位面积上的ZrB2纤维数可达到108根/cm2.

     

    Abstract: LaB6-ZrB2 eutectic in-situ composites with LaB6 as matrix and ZrB2 whiskers uniformly distributed in the matrix were prepared by the method of electron beam zone melting.The averag ediameter of the ZrB2 whiskers is 0.2～1.1m,and the number of ZrB2 whiskers perunitarea can be up to 108/cm2.
