Development of High Strength Sintered Steel by High Pressure Warm Compaction Using Die Wall Lubrication

Abstract:

The high pressure compaction without internal lubricant and the high green density even with the pore free density were achieved by the newly developed die wall lubricant for warm compaction. This developed die wall lubricated warm compaction followed by high temperature sintering resulted in improved mechanical property and almost no dimensional change. In this paper, the effects of increasing the green density on the sintered density, the dimensional change and the mechanical property are mainly discussed.
