| Abstract Scope |
The pursuit of achieving enhanced performance has led to the adoption of multi-scale segregated microstructure composites. These unique composites consist of two distinct regions: an outer ductile unmilled metal matrix region, which serves to constrain cracks while withstanding strain, and an inner region comprising of milled aluminium and reinforcements, providing strength. Current study highlights the development and characterisation of both conventional single-matrix composites and segregated matrix composites using aluminium as the matrix and aluminium nitride as the reinforcement for an Al-10wt% AlN composition. The composite fabrication process involves high-energy ball milling for 10 hours followed by 30 minutes of rotor mixing. Microstructure modifications are made based on the desired percentage distribution of the composite region (Pc) and matrix region (Pm). Structural, mechanical, and thermal analysis highlight the significance of segregated microstructure development and demonstrate how further adjustments to the Pc and Pm distribution expand the practical applications of this system. |
