Addtionally, on the basis of the two techniques, the equivalent heatconductance coefficient of the porthole flange in different heat transfer direction is analyzed.
The experimental results show that the relative density, hardness, relative specific conductance and heat conductivity of the billets are increased with increasing percentage composition of Cu.
结果表明，随着铜含量的增加，热挤压坯料的相对密度增加，同时相对导电率、相对热导率和硬度值也提高。

The strength of the coated diamond, the bonding force with the metallic matrix, heat resistance (sintering temperature of diamond bits) and conductance are all improved.
