Two phase transformations in the temperatures range of 20 700 °C were found.
Two phase transformations are generally observed for each type of SCLC polyethers.
Based on an analytical deduction, the crystallographic and lattice point correlations between the initial hcp and final fco structures are obtained, respectively, and the deduced correlations may also be of relevance for another two phase transformations: the hexagonal close-packed to body-centered tetragonal, and hexagonal close-packed to face-centered cubic martensitic phase transformations.
Plutonium metal undergoes five phase transformations below its melting temperature of 640° C (1,183° F).
Three phase transformations were identified beneath indentations in polycrystalline TbPO4, in deformation bands in (Gd0.4Dy0.6 PO4 fiber coatings after fiber push-out, and in polycrystalline (Gd0.3Tb0.7 PO4: xenotime → monazite, xenotime → anhydrite, and anhydrite → monazite.
We show that when the diameter of the nanotubes is larger than certain critical value, the nanotubes in the crystals will undergo three phase transformations: the closely-packed hexagonal phase I → assembled circular phase → new hexagonal phase II → isolated circular phase.
A single crystal with a selected composition of a Cu Al Ni shape memory alloy, undergoing two martensitic phase transformations when cooling from the common parent phase, β3→β′3+γ′3, has been studied by adiabatic calorimetry.
The body then metabolizes them through two phases of transformation: Phase I and Phase II.
As a function of transformation time, two stages of phase transformation can be clearly distinguished in the γ → α transformation of the interstitial Fe C alloy: a first, very fast stage and a second, sluggish one.
Trunov et al. [18] suggested that this is a result of the sequence of four polymorphic phase transformations (amorphous, γ, and α-alumina) [19], leading to a step-wise particle mass increase.
The coherent phase transformation between two equilibrium single-phase states producing several orientation variants of the product phase is considered.
