Description
Summary:Composites made by infiltrating B sub 4 C networks with aluminum, or its alloys, are of interest for lightweight armor applications. Image analysis plays an important part in correlating the microstructures of such composites with their mechanical properties. Accurate image analysis requires a high degree of perfection in the metallographic preparation, which is particularly difficult where the phases present have such disparate hardnesses and reactivities. Two preparation procedures have been developed that produce adequate contrast and definition for analysis of key microstructural features.
