Diffusion parameters in liquid phase sintering of the al-cu system

Within the framework of the conception of the priority of the diffusion of atoms from the liquid phase into the solid at their interface, a method of quantitative determination of diffusion parameters of interaction of solid and liquid phases by experimental curves of growth and densification of powder bodies during liquid phase sintering has been suggested. Results of the determination of diffusion parameters and volume changes of powder bodies of the Al-Cu system during sintering were produced on the basis of solution of the reverse and direct problems.
