Ti - ZrO_2 Interactions during Manufacturing of High Porous Ti/Ti-based MMC of Regulated Structure

摘要

The present paper reports a microstructure inspection of powder fabrication of regulated structure Ti/Ti-based metal matrix composites (MMC) utilizing sacrificial NaCl particles. Blending, compaction and sintering of Ti and YSZ reinforced Ti compacts containing NaCl resulted in regulated foam structures with porosities between 45 and 70 pet. SEM observations indicated that three pore sizes and morphologies were formed while XRD analysis suggested that the yttria stabilized zirconia (YSZ) reinforcements are unstable at the high temperature sintering conditions considered in this study.
