Effect of Sea Sand Content on Hardness of Novel Aluminium Metal Matrix Composite AA6061/Sea Sand

摘要

Sea sand containing ceramics compounds can be used as raw material for lightweight metal matrix composite material. A new composite AA6061/Sea sand with stir casting manufactured has been developed yet. Process parameters as particle treatment, stirring speed, stirring time, and the fraction of particles should be studied to high hardness of material. The effect of the fraction of sea sand particles on homogeneity and hardness is studied in this paper. The fraction 2-6%wt of sea sand particles are used for manufactured the composite. The result showed that hardness is affected by density, porosity and dispersed particles higher dispersed particles resulted in higher hardness of the material.
