Enhancement of ductility in B2-type Zr-Co-Pd alloys with martensitic transformation

► We found a high ductility of Zr-Co-Pd alloys caused by martensitic transformation. ► Zr50Co40Pd10 alloy had the considerably high total elongation of 22%. ► Deformation induced martensite was observed in the B2 phase near the fractured area. ► The enhancement of ductility is due to the transformation-induced plasticity.
