Abstract
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. The invention also concerns the powder used in the method.
Claims (19)
1. Process for the preparation of high density green compacts comprising the following steps:
-providing an iron or iron-based powder wherein less than about 5 % of the iron-based powder particles have a size below 45 µm;
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 from the die.
-providing an iron or iron-based powder wherein less than about 5 % of the iron-based powder particles have a size below 45 µm;
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 from the die.
2. Process according to claim 1 wherein the compaction is performed in a single step.
3. Process according to claim 1 or 2, wherein at least 50 %, preferably at least 60 % and most preferably at least 70 % of the iron-based powder consists of particles having a particle size above about 106 µm.

12. Process according to any of claims 1-11, wherein the compaction is performed at ambient temperature.
13. Process according to any of claims 1-11, wherein the compaction is performed at elevated temperature
14. Process according to any of claims 1-13 for preparing sintered products said process further including a single sintering step at a temperature above 1100°C.
15. Powder composition comprising an iron or iron-based powder wherein less than about % of the powder particles have a size below 45 µm; and 0.1-1.0 % by weight of graphite.
16. Powder composition according to claim 15 further including 0.05 - 0.6 % by weight of a lubricant.
17. Composition according to claim 15 or 16, wherein at least 50 %, preferably at least 60 and most preferably at least 70 % of the iron-based powder have a particle size above about 106 µm.
18. Composition according to claim 17, wherein at least 50 % of the iron-based powder particles have a particle size above about 212 µm.
19. Compositon according to any one of the claims 15-18 further including additives se-lected from the group consisting of alloying elements such as Mn, Cu, Ni, Cr, Mo, V, Co, W, Nb, Ti, Al, P, S and B machinability enhancing agents, hard phase materials and flow agents
