Powder Forging of in Axial and Radial Direction Graded Components of TRIP-Matrix-Composite

Powder metallurgy is one way of producing complex, graded structures that could allow material systems to be produced with properties tailored individual applications. However, powder requires the semi-finished products are very similar final component. It much more economical produce simple and then combine them by forging simultaneous compaction than forming complex components desired structure. it absolutely necessary structure maintained during process. In this study, pre-sintered cylindrical products, consisting axially as well radially components, were at 1100 °C. The microstructures, densities mechanical investigated verify effectiveness process route. was observed formed solid after compaction, in which reinforcing ZrO2 particles fully integrated into transformation-induced plasticity steel matrix.
