摘要/Abstract

摘要： 以B₄C, SiC粗粉为原料, 采用机械合金化制备高活性的B₄C-SiC超细复合粉体。通过XRD、SEM、LPSA和IR等测试技术研究球料比、过程控制剂及球磨时间对复合粉体性能的影响, 确定机械合金化制备B₄C-SiC超细复合粉体的最佳工艺条件, 研究机械合金化过程中粉体有序-无序转变过程。随后, 采用热压烧结工艺验证复合粉体的烧结活性。结果表明: 球磨机转速是250 r/min的条件下, 球料比为30:1, 过程控制剂为2wt%, 球磨时间为 120 h时, 可获得晶格无序的B₄C-50wt% SiC超细复合粉体; 该复合粉体在1900℃, 30 MPa热压条件下烧结1 h, 其体积密度为2.62 g/cm³, 达到理论密度的93%, 比普通混合粉体在相同热压条件下获得样品的致密度提高了8.1%; 机械合金化工艺制备的B₄C-SiC超细复合粉体具有极高的烧结活性。

Abstract: High active and ultrafine B₄C-SiC composite powders were prepared by the coarse powders of B₄C and SiC through the technology of mechanical alloying. Under testing techniques of X-ray diffraction, scanning electron microscope, laser particle size analysis and infrared absorption spectrum, by which studied the influences of ball to powder weight ratio, process control agents and milling time on composite powders, the best technological conditions of MA for preparing B₄C-SiC ultrafine composite powders could be confirmed. After studying order-disorder transformation of the composite powders during the process of MA, hot pressing sintering was adopted to verify the sintering activity of the composite powders. The results indicate that the lattice unordered B₄C-50wt% SiC ultrafine composite powders can be obtained when the ball to powder weight ratio is 30:1, process control agents 2wt%, milling time 120 h and the rotation speed 250 r/min. While the composite powders are sintered at 1900℃ with pressure of 30 MPa, the density of samples is 2.62 g/cm³and the relative density of samples attains 93%. The relative density of samples sintered with the composite powders is 8.1% higher than that of samples sintered with ordinary mixing powders. B₄C-SiC ultrafine composite powders prepared by mechanical alloying possess extremely high sintering activity.
