phase transition

n.
A change in a feature of a physical system, often involving the absorption or emission of energy from the system, resulting in a transition of that system to another state. The melting of ice is a phase transition of water from a solid phase to a liquid phase, requiring energy in the form of heat.

Engineers can look into microscale morphology and track the microstructure phase transformation during the print, and connect to the final as-printed material behavior in the platform.
Since marten-sitic phase transformation, twinning and superelasticity play a central role in shape memory alloys, we would like to discuss these two properties briefly.
In pure Co, the allotropic phase transformation occurs at around 417[degrees]C by a diffusionless martensitic mechanism [6].
The null hypothesis was that the flexural strength and the phase transformation of two Y-TZP materials colored by different procedures would not be affected by hydrothermal aging.
Here, a complex change involving phase transformation and phase segregation is witnessed.
The chemical composition and microstructure of Filler Materials for Welding and 3D Printing are purposely formulated to introduce a volumetric expansion from low temperature phase transformation to counterbalance the thermal shrinkage during welding and 3D printing and to control the residual stress and distortion of high-strength steel structures.
The result should contribute to deeper understanding of the phase transformation of carbon steel.
They introduced the strain-based order parameters (OPs) model to describe a cubic-to-tetragonal phase transformation consisting of inhomogeneous strain field associated with domain walls, constituent phases, and transformation precursors.
The peaks at 2[theta] = 27.3[degrees], 36.2[degrees], and 41.1[degrees] that are assigned to the rutile phase were of low intensities in the XRD pattern of undoped Ti[O.sub.2] but increased in intensity in the XRD patterns of all doped Ti[O.sub.2] photocatalysts indicating partial phase transformation had occurred by doping with Ag or carbon.
So far, the addition of tantalum has shown a significant effect on the microstructure, mechanical properties, and phase transformation temperature of shape memory alloys [23-25], due to its aptitude to reduce the transformation temperature, increase the thermal stability, and improve the strain recovery ([[epsilon].sub.reco]) and residual strain ([[epsilon].sub.res]) during thermal cycling.
In general, SMAs are being used in order to explore adaptive dissipation associated with hysteresis loop and the mechanical property changes due to phase transformation [4].
Preferred oxidation of aluminum should lead to a change of concentration in the surface near area and should induce a phase transformation of the i-phase into the [beta]-phase.
