Abstract
The effect of an (α+TiFe) -tempering on the static tensile properties of sintered Ti-Fe binary alloys was investigated in relation to the holding time in the (α+TiFe)-region, and the results obtained are summarized as follows. The unexpected increment of elongation was observed during the (α+TiFe)-tempering for both the two (α+β)-quenched Ti-2 wt% and 4 wt% Fe sintered alloys, and the brittleness was not noticed, where the precipitation of TiFe was not detected by SEM observation and X-ray diffraction analysis. It was also confirmed by the X-ray diffraction analysis that the iron content in the β-phase shifted from 11-12 wt% for the as (α+β)-quenched specimen to 14-15 wt% for the specimen (α+TiFe)-tempered after (α+β)-quenching.
