摘要: Abstract In this work, the Effective Thermal Conductivity (ETC) of closed-cell aluminum foams was measured in temperature range 100–500 °C. Analyses showed that ETC is proportional to relative density as well cell wall thermal conductivity, and inversely square tortuosity. Differences conductivity were found among foam samples. As conductivities Al, Ti 2 Al 20 Ca 4 decrease with hydrogen-related phase transition occurs, decreases temperature.
