The average number of valence electrons by atom (e/a) is parameter used characterize these alloys.
It is known that there is a linear correlation between the average number of valence electrons per atom and the martensite start temperature [13].
This is a sign of the fast crystallization and growth kinetics of the alloy, and suggests that heat removal during rapid solidification process induces directional grain growth of the formed crystalline phase.

Although the existing techniques for theoretical and numerical
modeling of material micro-structures [1-7] are successful in simulating the formation and
structures of grains on fine length scales, in most cases, comparisons between model predictions
and experiments could only be made statistically.
However, given the generic nature of the approach and virtually unlimited possibilities in material microstructures due to an endless range of material compositions under a diverse range of formation processes, a large number of experiments will be needed.

Average grain size were measured 220 µm and 360 µm for grinded hazelnut and peanut shells, respectively.
TS of peanut composites was found to increase until the 3rd reprocessing step while TS of hazelnut composite increased in a linear fusion with increasing number of reprocessing.
However IS of composites was found to increase with increasing number of reprocessing probably because of improvement of the dispersion of fillers.

It is similar to
the skin of the unit, covering the surface of the entity, which will not increase the number of nodes
(except for isolated nodes), only increase the number of units.
So that the grain growth will be different, this is in line with experimental results.
