Randomized trial investigates phase transformation in pure zirconium and hafnium, suggesting temperature and strain impact outcomes.

This research aims to understand how high-pressure shear strain influences the phase transformation from α to ω in zirconium and hafnium.
Used high-pressure sliding to induce phase transformation under varying conditions.
Applied high-energy X-rays for in situ analysis during high-pressure loading and heating.
Sample types included annealed and severely strained specimens processed by high-pressure torsion.
In zirconium, the α→ω transformation is promoted by high-pressure straining, more evident in HPT-processed samples.
Heating up to 180°C facilitated the phase transformation, suggesting thermal activation assistance.
In hafnium, the transformation was not confirmed due to inadequate pressure to reach the critical phase transition.

Masuda et al. (2026) studied this question.
