| Popis: | Static tensile properties of HIP'ed Ti-6A1-4V alloys after sintering at 1473 K for 3.6 ks by blended elemental powder metallurgy process were studied, and compared with those of HIP'ed Ti-6A1-4V powder compacts, made by Rotating Electrode Process (REP).Metallographic and fractographic observations were also carried out by light and scanning electron microscopy, and X-ray energy dispersion analysis.The tensile strength and ductility of HIP'ed Ti-6A1-4V alloy after sintering by blended elemental process using hydride-dehydride Kroll process sponge fines as the titanium source were clarified to be nearly the same as those of HIP'ed REP Ti-6A1-4V alloy. On the other hand, amarked ductility degradation was observed in the case of using Hunter process sponge fines as the titanium source, and it was confirmed that this behavior is closely related to the existing NaCI in the sintered compacts. |
