| Abstract: | Five phases of intermetallic compounds such as γ1, δ, ζ2, η2 and θ are formed in a lamellar manner at the Cu/Al interface. As the compounds grow, the copper phase shrinks in a parabolic manner. The parabolic rate constant is described as: k=11800 exp (-68400/RT). The hardness of the mixed powder compact increases with sintering time, and the degree of the increment becomes remarkably high as the copper content increases from 5 to 71mass%. The tensile strength of the compact increases with sintering time when the copper content is low, while it decreases when the copper content is high. The area reduction of the compact decreases at the beginning of sintering, but it recovers gradually with time when the copper content is low. The density of the compact decreases with sintering time. |
