Outline
Aluminum bronze was treated at 5 GPa and 750 ℃ for 15 min, after that its electric conductivity, thermal diffusion coefficient, heat capacity, and thermal conductivity between 25 and 600 ℃ were measured. Combining these data with the microstructure images, the effects of high pressure heat treatment on the thermal physical properties of aluminum bronze were investigated. The results showed that high pressure heat treatment can increase the thermal diffusion coefficient and decrease the heat capacity of aluminum bronze. Furthermore, the thermal conductivity of aluminum bronze after high pressure heat treatment increases with increasing temperature until 400 ℃, and then starts to decrease. Analysis shows that this is because the high pressure heat treatment makes the microstructures of aluminum bronze alloy change.
