Chemistry Elements to work on New Model.

[Metaphor]

What is the model you’re talking about? You’re inventing it?

Well, maybe yes or no. I don't know yet, but let's see.

Nitinol's unusual properties are derived from a reversible solid-state phase transformation known as a martensitic transformation, between two different martensite crystal phases, requiring 10,000–20,000 psi (69–138 MPa) of mechanical stress. At high temperatures, nitinol assumes an interpenetrating simple cubic structure referred to as austenite (also known as the parent phase). At low temperatures, nitinol spontaneously transforms to a more complicated monoclinic crystal structure known as martensite (daughter phase). There are four transition temperatures associated to the austenite-to-martensite and martensite-to-austenite transformations. Starting from full austenite, martensite begins to form as the alloy is cooled to the so-called martensite start temperature, or M_s, and the temperature at which the transformation is complete is called the martensite finish temperature, or M_f. When the alloy is fully martensite and is subjected to heating, austenite starts to form at the austenite start temperature, A_s, and finishes at the austenite finish temperature, A_f.

A great deal of pressure can be produced by preventing the reversion of deformed martensite to austenite—from 35,000 psi (240 MPa) to, in many cases, more than 100,000 psi (690 MPa). One of the reasons that nitinol works so hard to return to its original shape is that it is not just an ordinary metal alloy, but what is known as an intermetallic compound. In an ordinary alloy, the constituents are randomly positioned in the crystal lattice; in an ordered intermetallic compound, the atoms (in this case, nickel and titanium) have very specific locations in the lattice. The fact that nitinol is an intermetallic is largely responsible for the complexity in fabricating devices made from the alloy.

Seems to be congruent towards what I need on developing the compartmental phase of Ni as a tool paired with the creative program of Ti. And as I said, it's still working in progress. Perhaps, would have to make a synthetic version of these elements to be complemented into a single type. As for the fact that "nitinol is an intermetallic is largely responsible for the complexity in fabricating devices made from the alloy.", it's probably due to the algorithm of digits/lexemes in which were to be made by the nitinol seems to be one way to enhance the fluidity of process thus keep an eye out towards the level of impairment to be stable in any circumstantial effects. However, so far, the reason is unknown so I could only make a hypothetical reasoning according to what has been explained by this and it could be furtherly elaborated by these schematic 3D pictures below:

There were some stuff that might explain the way how Nitinol, or allegedly known as NiTi, works to be deformed into a new shape due to its superelasticity:

"When a shape memory alloy is in its martensitic form, it is easily deformed to a new shape. However, when the alloy is heated through its transformation temperatures, it reverts to austenite and recovers its previous shape with great force. This process is known as shape memory."
