| Resumo |
The mechanical properties (yield stress, ultimate tensile stress and elongation) of alloy 20Cr32Ni + Nb subject to isochronal aging at temperatures between 670 and 820 degrees C for 200 h were investigated using samples extracted from a centrifugally cast tube. The results confirm the occurrence of embrittlement in the aged samples, with maximum embrittlement observed around 770 degrees C without significant gain in strength. (C) 2008 Elsevier Ltd.
