Effect of sintering environment to the physical properties of Al/calcined dolomite composite

Abstract

Composites of pure aluminum with calcined dolomite powders of <65□m in size were prepared by mechanical milling. Fabrication involves the mixing of reinforcement particles with the metallic powder followed by consolidation and sintering processes. The effect of two different types of sintering environment to physical properties of Al/calcined dolomite composites will be presented in this paper which are nitrogen and argon gas. Materials were characterized through density, percentage of dimensional changes and hardness properties.
