Development of High Strength Ferrous Sintered Components and Near Net Shape Compacting Technology

Abstract

For the new practical application and the expansion of ferrous sintered components, the improvement of mechanical properties of sintered steels and the advancement of the near net shape compacting technology are important. In this paper, the following two solution examples for these subjects are mentioned. One is an improvement of mechanical properties of the sintered steels by the addition of carbon and/or hard particles to the sintered steel with high copper contents. The other is an analysis of micro crack formation during a practical powder compaction process on the basis of the experiment and the FEM simulation.
