Synthesis of aluminum alloy - fly ash composites and their characterization.

摘要

This thesis is to study the characteristics of fly ash particles as a potential additive to metal matrices and the synthesis of selected aluminum (alloy) - fly ash composites by liquid state processing and characterizes the behavior of these composites, including (a) casting behavior, (b) interaction between aluminum matrix and fly ash particles, (c) the chemical reactions between molten aluminum and fly ash particles during synthesis, and (d) microstructure and selected physical and mechanical properties of the composites.;The major results are: (a) The density of precipitator fly ash is 1.9 to 2.4 g/cm
