Tensile properties of sinter hardened powder metallurgy components machined in their green state

Abstract

With the increasing demand for sinter hardened powder metallurgy components, there is a growing need to solve the poor machining behaviour that characterises them. Approaches based on green machining appear promising to extend tool life and reduce machining costs. The present study deals with the sintered properties of cylindrical tensile specimens green machined. Results show that tensile properties of components machined in their green state are identical to those of components machined after sintering.
