Debinding and sintering of warm compacted and binder-treated complex iron-base part
Regular elemental powders were used in warm flow compaction instead of the expensive micron-sized powders to fabricate cross-shaped parts.Debinding behaviors,sintering properties and shape consistency of the sintered parts were studied.Binder removal was accomplished by heating green compacts at intermediate temperatures with optimal heating rates until the debinding temperature was reached.Results show that by controlling debinding process,complex parts with good shape consistence can be obtained by warm compaction of binder-treated powder.Fine and shiny surface was obtained and no surface defect can be observed for sintered parts debinded at 2 ℃/min,while defect can be observed in sintered parts debinded at 4 ℃/min.
