Comparisons were made to previous thermal expansion values of other MCrAlY coatings.
Average ASR expansion values of 0.012 and 0.002 % at 28 days were observed for untreated and thermally treated specimens, respectively, indicating the significant effect of thermal curing on UHPC ASR expansion.
A non-parametric test was chosen because the pre-expansion values of all considered parameters were equal to zero (non-normal distribution).
This difference between clade A and grade B is reflected in differences between the pre- and post-expansion values of θ or the COI data, though this difference is not evident in the θ values calculated from the shorter cytB sequence fragment (Table 2).
Since Zn and Ti have very similar physical properties and particularly the crystalline properties like both have same hexagonal type of crystal structure and the coefficient of linear expansion value differ slightly from each other.
However, we were only interested in mechanical strain, so assigned the coefficient of thermal expansion a value of zero.
Similar lattice expansion values (<1%) of perovskite compounds after hydrogenation have also been reported in previous studies [19, 24].
Glass comes in a range of COE (Coefficient of Expansion) values – this is the rate at which glass expands when heated, if you try and mix different COEs then the glass will probably stress and crack as it cools.
Cellular expansion values corresponded to numbers of cells counted after 7, 14 and 21 days of culture divided by the number of cells initially plated.
The composites exhibited lower coefficient of expansion values than the alloy.
