It was found that the transformation temperatures of the Ni51Ti49 binary alloy increased drastically by an addition of 0-4 at. pct Ta, but only slightly when the concentration exceeded 4 at. pct, the addition of Ta greatly decreases the sensitivity of the martensitic transformations to the variation in the Ni-Ti ratio. The addition of Ta to the NiTi binary alloy can improve its X-ray visibility. 关 键 词：NITI Effects of Ta Addition on NiTi Shape Memory Alloys TA
