Abstrakt: The 77 K stress-strain curves of high purity Zr, commercial purity Zr, high purity Ti and commercial purity Ti, which are all significantly different, were analyzed by the Crussard and Jaoul method. The evolution of the mechanical twin structure in these specimens was also studied using quantitative optical microscopy. It was generally observed that changes in the nature of the twin structure development correlated with changes in the C-J deformation stages. Constant work hardening rate stages tend to appear at higher strains if the rate of increases of the twin volume fraction is large. [ABSTRACT FROM AUTHOR]
