A study has been made on the static tensile properties for both the as sintered and the β-quenched (water-quenched after holding at 1173K for 1.8 ks) Ti-Co binary alloys.
The elongation of the as-sintered Ti-Co binary mixed powder compacts lowered with increasing amount of Co content, and it was recognized that the value of elongation for the specimen containing only 2 wt%Co was lower than 5%. This elongation was not improved by the β-quenching, and the river pattern was observed in the α-phase region for both the as-sintered and the β-quenched specimens.
The above mentioned brittleness of the α-phase was confirmed to be related to the enrichment of oxygen in the α-phase.
