Component Level Tensile Testing of Press & Sinter Steels
Component designers often want to know the mechanical properties of press and sinter materials. Usually standard test bars can be used to confirm the properties of a press and sinter alloy, but without actual knowledge of the component properties, which can vary significantly. This is due to the size of most parts, which does not lend itself to cutting standard samples directly from the component. Subsize tensile samples have been developed and the methodologies for using them worked out. Examples will be given of applications of these subsize specimens to mapping out material properties with location and heat treatment of actual components made from PM steels by press and sintering. With this approach, actual verification of properties can be performed and supplied to purchasers of press and sintered parts. Property variation with density will also be shown for this methodology.
