Evaluation of metal powder forming parameters at above ambient temperature

This paper presents the results of an experimental investigation to evaluate the forming parameters for the compaction of iron powder ASC100.29 at above ambient temperature. A lab-scale uniaxial die compaction rig was designed and fabricated which enabled the generation of green samples from the sta...

A lab-scale uniaxial die compaction rig was designed and fabricated which enabled the generation of green samples from the stated powder mixed with lubricant at different forming parameters.
