真空热压制备SiCf/Ti-43Al-9V复合材料微观组织及化学元素分析

Analysis of Microstructure and Chemical Element of SiCf/Ti-43Al-9V Composites Prepared by Vacuum Hot Pressing

通过真空压制制备了SiCf/Ti-43Al-9V复合材料,并通过X射线衍射仪、金相显微镜和能谱仪对复合材料的显微组织和化学元素进行了分析。结果表明,SiCf/Ti-43Al-9V复合材料基体组织的形成不仅与塑性变形过程中储存的应变能有关,还与界面反应和化学元素有关。其中C是α相形成的稳定元素,V是B2相形成的稳定元素。

The SiCf/Ti-43Al-9V composite material was prepared by vacuum hot pressing, and the microstructures and the chemical elements were analyzed by X ray diffraction, optical microscope and energy spectrometer. The results show that the formation of matrix microstructure of the SiCf/Ti-43Al-9V composites depends not only on the strain energy which was stored in the process of plastic deformation, but also on the interracial reaction and chemical elements. C is a stable element of forming of phase, V is a stable element of forming B2 phase.
