EVALUATION OF FORGED ALUMINUM MATRIX COMPOSITES REINFORCED WITH CARBON NANOTUBES (CNTs) FABRICATED BY COMPOSITE GAS GENERATOR (CGG) PROCESS

摘要

In this study, aluminum based metal matrix composites(ALMCs) with multi-walled carbon nanotubes(CNTs) as reinforcement was produced by a recently developed composite gas generator(CGG) process. Furthermore, the liquid composites with well dispersed CNTs was forged to the slug shape part by the melt forging process, followed by heat treatment with several holding times, and microstructures and mechanical properties of forged products also were evaluated. Results shown that mechanical properties were enhanced compared to those of products without reinforcements.
