Metal Powder Industries Federation (MPIF), Princeton, N.J., released Fatigue Design Concepts for P/M Parts and Required Material Data, a 32-p overview by C.M. Sonsino. The publication provides design engineers with guidelines on the unique characteristics of P/M materials and therefore on the design concept and rules appropriate to P/M products. It also includes information on the required fatigue notch factors for the presence of external notches and the approach to following for mean stress effects.
