The key effects of SMAs associated with the phase transformation are pseudoelasticity and shape memory effect.
No negative effects were found on the phase transformation and the mechanical properties (surface microhardness and fracture toughness).
Nanocatalysts have the advantage that their properties can be engineered by tuning size and composition, alloying, and using phase transformations such as mixing, segregation, and ordering for surface structure.
In the austenite phase transformation, the growth of the austenite grain is controlled by the diffusion of the element.
The cubic nonlinearity allows us to capture the hysteretic phase transformation properties like shape memory effect and pseudoelasticity as a function of temperature.
The highest anatase to rutile phase transformation occurred at 500[degrees] C when Ti[O.sub.2] was doped with carbon only, with less rutile formed in Ag/C codoped Ti[O.sub.2] (0.7% Ag) photocatalyst with 2.20% anatase and 97.80% rutile.

Moreover, [L.sub.0], L, [L.sup.A.sub.0] and [L.sup.A] are parameters related to critical stress for phase transformation.
* Oxidation of aluminum by changing concentration in the near-surface area induces phase transformation. Such transformations are abrupt since intermetallic phases are observed;
This enhancement of mechanical properties of NiTi instruments can be considered to be the effect of the composition of microstructures and modification of phase transformation behavior caused by thermomechanical treatments.

These manual procedures could trigger the t [right arrow] m phase transformation and grinding, creating a compressive stress layer, due to an increase in the volume of the material (zirconia) by approximately 3%, in addition to producing some surface defects in the material.
