Interface reactions between SiC/Zr and development of zirconium base composites by in-situ solid state reactions

摘要

Diffusion reactions between Zr/SiC and Si/ZrC were studied with a "powder in cup" technique at 900-1100 deg C. An essentially layered structure Zr/ZrC_x/Zr_5Si_3C/ZrC/SiC and an extended two-phase structure Si/…ZrC develop in the reaction zones, respectively. The latter microstructure may be favorable for in site prepared Zr based composites.
