Abstract
The thermal conductivity and electrical conductivity of CuAlBi alloy before and after 16GPa high pressure treatment were measured by thermal constant tester and conductivity gauge when it was heated at 700°C and lasted for 30min. And the effects of high pressure heat treatment on thermal conductivity and electrical conductivity of CuAlBi alloy were discussed by its microstructure. The results show that the thermal conductivity variation trend of CuAlBi alloy before and after 3GPa pressure heat treatment is almost the same in range of 25600°C, high pressure can reduce the thermal conductivity and electrical conductivity of CuAlBi alloy, the thermal conductivity and electrical conductivity of the alloy decrease with the increment of pressure in less than 3GPa, when the pressure is over 3GPa, the variation of thermal conductivity and electrical conductivity are not obvious.
