Structural phase transformations and shape memory effect in ZrCu along with Ni and Hf additions
Ni replacement of Cu in ZrCu high temperature shape memory alloy results in the increase of the temperatures of the martensitic transformation (MT) [1]. Once the Ni content reaches 20 at.%, the temperatures of MT are becoming higher than the temperature of crystallization of the amorphous alloy with...

| description | Ni replacement of Cu in ZrCu high temperature shape memory alloy results in the increase of the temperatures of the martensitic transformation (MT) [1]. Once the Ni content reaches 20 at.%, the temperatures of MT are becoming higher than the temperature of crystallization of the amorphous alloy with the same composition [2] and crystallization from the amorphous state in this case takes place through formation of B19` phase without any visible signs of the nanoscale phase separation. In this regard, little is known about the influence of Hf additions onto phase transformations in ZrCu. The present work is dedicated to the study of structure and phase formation upon alloying of ZrCu by Ni and Hf by means of structural and thermal analysis. Their influence onto shape memory behavior will be discussed. |
