Computer Modeling of Basic Physico-Chemical Processes for DSEC Composites of System LaB6-MeB2(MeTi, Zr, Hf) at Macro-, Meso- and Microstructure Scales

Abstract

This report results from a contract tasking I.M. Frantsevich Institute for Problems of Materials Sciences NAS of Ukraine as follows: Employing the methods of computer modeling, this effort is to investigate regularities of formation of microstructure of ceramic in-situ composites with the purpose of optimization of their physical and chemical properties and appropriate service characteristics. The object of this investigation is eutectic boron-boride composites (a model system is LaB6-MeB2 (Me-Ti, Zr, Hf)). The tasks of this investigation are to define regularities of crystal-orientation ratios in conditions of eutectic co-crystallization of specified composites (that provides knowledge about a nature of formation of interfaces at directed solidification) and to model fracture processes of the investigated composites at chosen schemes of loading. Computer modeling shall be performed on the base of experimental data provided by IPMS colleagues (Dr. W. Paderno's REE Refractory Compounds Laboratory) and Dr. Ali Sayir at Case Western Reserve University (CWRU).
