PRODUCTION OF WATER ATOMIZIED IRON POWDER FOR POWDER METALLURGY AND DIMENSIONAL CHANGE CONTROL METHOD AT SINTERING

摘要

PURPOSE: To produce a sintering product having a dimensional change rate as designed, particularly to establish the control method for producing the sintered product which shows a stabilized high dimensional change rate suitable for sizing work. ;CONSTITUTION: By controlling Na content in atomized water in the reducing direction, the water atomized iron powder having a lower Na content is produced, particularly supplying the water atomized iron powder having ≤300ppm Na content.;COPYRIGHT: (C)1994,JPO
