Tensile Test Methodology for PM Components


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. 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. Several PM steels have been evaluated by testing standard test pieces versus subsize samples. Correlation between the two methods will be described and the use of other new methods, such as Automatic Ball Indention will be evaluated. 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.
