Powder metallurgy is one way of producing complex, graded structures that could allowmaterial systems to be produced with properties tailored to individual applications. However,powder metallurgy requires that the semi-finished products are very similar to the final component.It is much more economical to produce simple semi-finished products and then combine them bypowder forging and simultaneous compaction than forming complex components with the desiredgraded structure. However, it is absolutely necessary that the graded structure of the semi-finishedproducts is maintained during the forming process. In this study, pre-sintered cylindrical semi-finished products, consisting of axially graded as well as radially graded components, were producedby powder forging at 1100◦C. The microstructures, densities and mechanical properties of the finalcomponents were investigated to verify the effectiveness of the process route. It was observed thatthe components formed solid structures after compaction, in which the reinforcing ZrO2particleswere fully integrated into the transformation-induced plasticity steel matrix.
