Abstract

Kawasaki Steel has developed Japan's first iron powder pre-mix "Clean Mix HW Series" specially designed for warm compaction by incorporating "KW-wax", a lubricant with high performance during warm compaction process. KW-wax realized the powder characteristics - flow rate and apparent density - stable in the wide temperature range from room temperature to 423 K. Because of this stability. HW Series does not require the rigid control of the powder temperature in the compacting process of mass production. It was also found by the study about compacting process that KW-wax promoted particles rearrangement during compaction and gave green density higher than 7.3 Mg/m3, having pore structures homogeneous in size and shape. The homogeneous structure of green compacts resulted in the improvement of mechanical strength of sintered and heat-treated compacts.
