    isothermal dynamics, kinetic arrest, and nonergodic anelastic strain based on
    thermal activation of martensitic transformations'

## Description

- description: Much of the impact of thermal activation on the low-temperature dynamics
    of the thermoelastic martensitic transformation (MT) remains unresolved. This
    study introduces the concept of viscosity of superelasticity, referred to herein
    as “viscosuperelasticity,” to comprehensively interpret the slow dynamics of stress-induced
    isothermal MT at low temperatures. The thermal activation dynamics underlying
    this concept allow for deriving the time-temperature-transformation (TTT) diagrams
    at any holding stress from the temperature- and strainrate-dependent superelastic
    stress-strain curves. Experimental results for isothermal forward and reverse
    MTs comprehensively agree with the derived TTT diagrams, disclosing the nonreciprocity
    in the dynamics between the forward and reverse MT paths. One of the representative
    manifestations of viscosuperelasticity is the difference in the cooling/heating-rate
    dependence of the forward/reverse MT starting and finishing temperatures (TMs,
    TMf, TAs, and TAf). A significant decrease in TMs and TMf with increasing cooling
    rate explains kinetic arrest, and a gradual increase in TAs and TAf with increasing
    heating rate explains the difficulty in detecting the isothermal evolution of
    the reverse MT. The TTT diagrams also enable the impact of thermal activation
    upon dynamic cooling/heating to be evaluated quantitatively, explaining the nonergodic
    thermal-history dependence of anelastic transformation strain, which has been
    believed to be an essential signature of strain glass. The concept of viscosuperelasticity
    offers a comprehensive interpretation of nonreciprocal isothermal dynamics, kinetic
    arrest, and nonergodicity in the anelastic strain as manifestations of thermal
    activation of MTs.
