Abstract

Microstructural characterization by transmission electron microscopy (TEM) has been used in an investigation of the effects of interstitial alloy content on the mechanical properties of P/M tantalum. Compacts were prepared by cold isostatic pressing (CIP) at 50 ksi (345 MPa) followed by hot isostatic pressing (HIP) at 30 ksi (207 MPa) at 1600°C. Increases in both yield and flow stresses were observed in ambient temperature, quasi-static compression tests due to increases in interstitial alloy content. Variations in yield stress were attributed to solid solution strengthening due to interstitial elements, since no oxides, nitrides or carbides were observed via TEM.
