Abstract
The invention relates to methods of forming sintered compacts of low alloy steel composition to high density at ambient temperature. The invention provides for a method of forming sintered powder metal articles by forming the sintered powder metal in a die cavity having a clearance for movement of said sintered powder metal to a final shape with increased density after compaction wherein the formed sintered powder metal article has a compaction length which is approximately 3 to 30% less than the original length.
