Interparticle movement and the mechanical behavior of extruded powder aluminum at elevated temperature

OSTI ID:426908
This paper proposes a model and mechanism, based on relative motion of the extruded aluminum particles, to explain these effects. Quantitative stereology is used to support the concept. Stress-strain relations are derived for the uniaxial and biaxial behavior of powder aluminum and they are seen to fit the data from a number of uniaxial and tension-torsion test specimens. Implications of the model for forming of extruded powder metal products are discussed
