Abstract

Fatigue testing of powder metallurgy (PM) steels, which can be considered to exhibit some ductility on both the macroscopic and microscopic scales, can be hampered by unpredictability of results due to inappropriate specimen configuration. This paper demonstrates the use of a V-notch specimen configuration in fatigue which produces fatigue data with a minimum of scatter. The effects of pressing pressure (and hence porosity) and heat treatment are investigated. The testing has been done as a proof of approach rather than a fundamental investigation of fatigue.
