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 .
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
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.
