Effect of grain size on transformation temperatures in a grain-refined, copper-based, shape-memory alloy☆
TLDR
In this paper, the effect of grain size on transformation temperatures has been found to follow the Hall-Petch relationship, where the transformation temperatures shifted to lower temperatures as grain size decreased, except for the temperature at which no further shape change occurred on cooling.About:

Grain size and pseudoelastic behaviour of a Cu–Al–Be alloy
TL;DR: The effect of grain size on the pseudoelastic behavior of a Cu-11.4.% Al-0.5 wt.% Be shape memory alloy was studied in this article, where Annealing at 1073 K leads to grain growth with a kinetic exponent around 0.5.
