The structure-property(S-P) correlation,especially in the context of high-temperature oxidation, in ZrB2-MoSi2 based Ultra High-Temperature Ceramic Matrix Composites (UHTCMCs) have been extensively investigated for quite some time since the last 25 years and a countless amount of published data is presently available in this field.On the other hand,emergence of correlative microscopy [1] has completely revolutionised the world of materials research, in a number of ways.However,owing to the challenges of sample preparation, there has hardly been a literature aimed at understanding the aforesaid phenomenon of understanding S-P correlation,based on oxidation in ZrB2-MoSi2 UHTCMCs,which,in future, may open up new frontiers of research in UHTCMCs.The present review intends to discuss some of the most interesting data published existing in this field and intends to provide a brief overview of the challenges associated along with some of the currently unexplored avenues in this field,especially in terms of fundamental research.However,in view of the enormous amount of research already done in understanding oxidation-based S-P correlation in these materials,the author does not claim to address all the issues which may be associated with understanding the same.
