METHOD OF PREPARING IRON-BASED COMPONENTS BY COMPACTION WITHELEVATED PRESSURES

摘要

The present invention concerns a process for the preparation of high density green compacts comprising the steps of providing an iron-based powder essentially free from fine particles; optionally mixing said powder with graphite and other additives; uniaxially compacting the powder in a die at a compaction pressure of at least about 800 MPa and ejecting the green body. T he invention also concerns the powder used in the method.
