Abstract
The work presented in this thesis is an investigation of the hot forging of powder preforms in which different powders are used in various parts of the forging. A consideration of the possible advantages and applications of this type of forging is given with reference to the
relevant published literature.
In the powder compaction part of the process the powders were pressed in -two layers. This was followed by the sintering operation, after which the preform was hot forged in a closed die to give simple consolidation without appreciable flow. The two powders used in these tests were ATST-A low alloy atomised steel powder and AHC 100.29 atomised iron powder.
Tests were carried out over a range of processing conditions, and mechanical and metallurgical tests were performed in both the as-sintered and as-forged conditions.
Particular attention was paid to the properties of the bond between the two materials.
Recommendations are made concerning the processing conditions under which the optimum properties are obtained for the particular powders being investigated. Finally proposals are made for future work on the forging of two part powder preforms.
