Computational Design of ZrO2-SiO2 Coatings for Oxidation of ZrB2/ZrC Composites Containing ZrSix Intermetallics at 1700 degrees C

Abstract

The research group investigated specifically the microstructural phases by integrating the computational mechanics and strategic experimentation of a ZrB2/ZrC/Zr-Si composite at ultrahigh temperatures (>=1700 degrees C) in an oxidizing atmosphere. The objective of the proposed research was to study the computational aided design of ZiO2-Si02 coatings for ZrB2/ZrC/Zr-Si composite developed by reacting B4C with Zr-Si melts through the following two integrated research thrusts: (1) Investigate the effect of microstructural design on the fundamental durability of ZrB2/ZrC/Zr-Si for use at ultrahigh temperatures (2) Investigate the processing of B4C with Zr-Si melts to create the desired scale interphase with ZrSix precipitates as determined by the numerical modeling.
