Abstract

An approach was studied that sets the heat treatment conditions to increase thermal conductivity after achieving the mechanical properties demanded of aluminum casting alloy parts. The heat treatment conditions that increase thermal conductivity were verified by focusing on the behavior of solute atoms that solid solute in the aluminum metal matrix and obstruct thermal conduction in AC4B, an aluminum casting alloy used as a material for cylinder heads. This study is applicable to heat treatment type aluminum alloy in general, and can also be expanded to aluminum alloy parts with high demand for heat dissipation properties. In addition, the close relationship between thermal conductivity and electrical conductivity indicated the potential for a simple alternative method of measuring thermal conductivity.
