Based on the characteristic of high energy milling and the micromechanics of com-
posite material, a plastic constitutive equation is implemented for milled composite
powders. To check the equation, the extrusion of Ti/Al composite powders prepared
by high energy milling was simulated. It was from the numerical analysis that the pre-
dicted extrusion pressure mounted up with milling time and extrusion ratio increasing,
which was perfect agreement with experimental results.
