Popis: Static tensile properties of HIP'ed Ti-Co binary alloys containing 2 wt% or 4wt%Co were studied, and metallographic and fractographic observation were also carried out by scanning electron microscope and X-ray energy dispersion analysis.Despite the low level of oxygen content, the HIP'ed specimen using Hunter process sponge fines as titanium source, showed poorer ductility properties than the HIP'ed specimen using hydride-dehidride Kroll process sponge fines of high oxygen content as titanium source, and it was confirmed that the above mentioned ductility degradation was closely related to the existing NaCl in the HIP'ed specimen using Hunter process sponge fines. Brittle fracture was observed in a part of the specimen using Hunter process sponge fines, which is also considered to be due to the above mentioned NaCl existing in the HIP'ed specimen using Hunter process sponge fines.
