Jerks of the phase transformation are shown over a small temperature interval of 0.5 K for three scanning rates. Avalanches are shown as jerks while the front propagation constitute a continuous background. With increasingly slower scanning rates the individual avalanches become well resolved.
(Color online) Power law dependence of the jerk energy and its statistical analysis in the maximum likelihood method (inset). The inset shows plateaus at the most reliable exponents near ɛ = 1.8 ± 0.1.
(Color online) Total enthalpy (a) of the transformation process and jerk-related enthalpy (b). The jerk enthalpy at the faster rates r 1 = 0.04 Kh−1 and r 2 = 0.29 Kh−1 are virtually identical. The slowest run (r 3 = 0.001 −0.07 Kh−1) had stops in its time evolution and showed a slightly larger jerk enthalpy.
Statistical distribution of the waiting time between jerks. The quantitative parameterization of the distribution at p(wt) ∼ wt −(γ–1)exp(−wt/τ) n leads to n = 1, γ = 0.7, and τ = 460 s.
