Strain hardening and failure of powder metallurgy iron

An Investigation For Optimal Tool Kinematics In Powder Compaction Cycle To Minimize Density Gradient In Green Powder Compacts

“…As explained in previous sections, the friction coefficient at powder-tool interfaces is a function of various physical and material parameters, and is nonlinear in nature. Generally, for simulation analysis of metal powder compaction, an average friction coefficient value is employed [23,43,45,48,49,50,70,88,90,101,102,112,129]. The typical recommended friction coefficient value for simulation of iron-based powder compaction is 0.1 [27,90,111].…”

“…Figure23. A shear-plate device consisting of: (1) optical transducer, (2) transducer, (3) powder compact disc, (4) parallelepipedic slab, (5) force transducer, (6) hydraulic press, (7) cylindrical die, and (8) press[19].…”
