摘要

在粉末冶金的基础上

结合半固态金属加工技术和陶瓷成形的发展

提出陶瓷基复合材料伪半固态触变成形工艺并且以SiCp为基体

Al[φ（Al） =3 0 % ]为增塑相

通过该工艺成形卫星角框架制件。结果表明

该工艺成形的零件微观组织比较均匀

HV可达 6.43GPa

应变ε约为 0 .5 %

抗拉强度约为 3 0 0MPa

为陶瓷复合材料以及高熔点材料在更多领域中的应用起到推进作用。

Abstract

A new forming method

the ceramic matrix composites thixoforming in pseudo-semi-solid state

was presented based on the powder metallurgy in combination with the semi-solid metal forming and the developing direction of the ceramic forming in the 21st century. The angle-frames were produced by the method with SiC p as the matrix materials and 30Al as the plasticization phase.The results show that the component’ microstructure with 6.43 GPa Hv and about 0.5% strain stress as well as about 300 MPa tesile strength is homogeneously formed. It will play a very important role in promoting the application of the ceramic matrix composites and high melt point materials in more fields.
