Effect of green machining on the tensile properties and fatigue strength of powder metallurgy sinter-hardenable steel components

A study was carried out to determine if green machining of powder metallurgy sinter-hardenable steel components had detrimental effect on their tensile properties as well as their fatigue resistance. Results show that tensile properties and axial fatigue resistance of green machined specimens and specimens machined after sintering are statistically identical.
