采用机械合金化工艺制备SiC质点弥散分布的Ti－6Al－4V复合粉末

HOMOGENEOUS DISPERSION OF SiC IN Ti-6Al-4V BY MECHANICAL ALLOYING

对连续纤维增强和颗粒增强金属基复合材料的优缺点进行了评述。为制备ＳｉＣ质点弥散分布的Ｔｉ－６Ａｌ－４Ｖ复合粉末采用了机械合金化工艺技术。用ＸＲＤ和ＳＥＭ研究了机械合金化过程中粉末形貌、粒度和晶体结构的变化。

Advantages and disadvantages of metal-matrix composites reinforced by continual fibers and ceramic particles are discussed in this paper. Mechanical alloying process was employed to prepare the SiC dispersed Ti-6Al-4V composite powder. Variation of particle morphology, particle size and crystal structureduring mechanical alloying are studied by XRD and SEM.
