FEM simulation on the warm compaction of AlSc composite powder.

In this paper, the compaction densification process of Al and Sc composite powers was studied using the finite element method (FEM). The effects of compaction pressure and temperature on the compaction process, macro and micro properties of the AlSc composite compacts were systematically studied. And those properties such as relative density and distribution, stress and distribution, and residual elasticity were quantitatively characterized and compared. The results show that the relative density of AlSc composite powder compact increases with the temperature to a high value and then keeps constant, and the high local relative density in the compact locates at the top region of the axial cross section when the pressure is fixed. And the axial and residual elasticity decrease with the temperature. [ABSTRACT FROM AUTHOR]
