Specimens from the center and the outer surface of Abee exhibit identical microstructures within their metal phase—platelets of an iron carbide. Thus the entire body must have cooled at a nearly uniform rate. The density, heat capacity, and thermal conductivity have been measured and used in a theoretical heat flow analysis. From these calculations and observations it is concluded that Abee cooled from 700 °C to 200 °C in about two hours.
