The improvement of tensile ductility of B2-type ZrCo-based alloy were performed by martensitic transformation. The mechanism of ductility enhancement in those alloys was also discussed. The tensile strength and elongation were increased by substituting Ni or Pd or Pt for Co in the ZrCo-based alloy. The deformation-induced martensite was dominantly formed in the B2 parent phase near the fractured edge. Consequently, we conclude that the remarkable enhancement of the ductility is due to the transformation-induced plasticity associated with the deformation-induced martensite.

B2型基于ZRCO合金的拉伸延展性的改善是通过Martensenitic Transformation进行的。还讨论了这些合金中延性增强的机制。通过将Ni或PD或PT代替基于ZRCO的合金中的CO来增加拉伸强度和伸长率。变形诱导的马氏体主要在骨折边缘附近的B2父相中形成。因此，我们得出的结论是，延展性的显着增强是由于与变形诱导的马氏体相关的转化诱导的可塑性所致。
