What is the Special Properties of Nitinol

U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the Nitinol will also increase.

What is Nitinol?

Nitinol is a shape memory alloy, which is a special alloy that can automatically restore its own plastic deformation to its original shape at a certain temperature. Its expansion rate is more than 20%, its fatigue life is up to 1*10 to the 7th power, its damping characteristics are 10 times higher than that of ordinary springs, and its corrosion resistance is better than the current best medical stainless steel, so it can meet various engineering and It is a very excellent functional material for medical application requirements.


In addition to its unique shape memory function, memory alloys also have excellent characteristics such as wear resistance, corrosion resistance, high damping and superelasticity.


Special properties of Nitinol

Shape memory: When the parent phase of a certain shape is cooled from above the Af temperature to below the Mf temperature to form martensite, the martensite is deformed at a temperature below Mf, and heated to below the Af temperature, accompanied by reversal. Phase transition, the material will automatically return to its shape in the parent phase. In fact, the shape memory effect is a thermally induced phase transformation process in Nitinol.


Superelasticity The so-called superelasticity refers to the phenomenon that the specimen produces a strain far greater than the elastic limit strain under the action of external force, and the strain can automatically recover when unloaded. That is, in the state of the parent phase, due to the action of external stress, the stress-induced martensitic transformation occurs, so that the alloy exhibits mechanical behavior different from ordinary materials. Its elastic limit is much larger than that of ordinary materials, and it no longer obeys Gram's Law. In contrast to shape memory properties, superelasticity has no thermal involvement. All in all, hyperelasticity means that the stress does not increase with the increase of strain within a certain deformation range, and hyperelasticity can be divided into linear hyperelasticity and nonlinear hyperelasticity. 


In the former stress-strain curve, the relationship between stress and strain is close to linear. Nonlinear superelasticity refers to the result of stress-induced martensitic transformation and its inverse transformation during loading and unloading in a certain temperature range above Af, so nonlinear hyperelasticity is also called transformation pseudoelasticity. The phase transformation pseudoelasticity of Nitinol can reach about 8%. The superelasticity of Nitinol can vary with the heat treatment conditions, and when the archwire is heated above 400ºC, the superelasticity begins to decrease.


Corrosion resistance: Studies have shown that the corrosion resistance of nickel-titanium wire is similar to that of stainless steel wire

Twitter recently announced that it had reached an agreement with Musk to take full ownership of the company for $54.20 per share, or about $44 billion in cash.  After the deal, Twitter will become a privately held company. The deal, which has been unanimously approved by Twitter's board but still requires shareholder and regulatory approvals, is expected to close in 2022.  

After Tesla CEO Elon Musk's acquisition of Twitter was finalized, Twitter founder Jack Dorsey sent out a series of six tweets expressing his expectations for Musk.  

Dorsey called Twitter his biggest regret, saying, “The idea and service is all that matters to me, and I will do whatever it takes to protect both. Twitter as a company has always been my sole issue and my biggest regret. It has been owned by Wall Street and the ad model. Taking it back from Wall Street is the correct first step.  

"In principle, I don't believe anyone should own or run Twitter," Dorsey goes on. He thinks the service is a public good.

He called Musk a "singular solution" to Twitter's problems, "Elon's goal of creating a platform that is" Maximally trusted and inclusive "is the right one." He wrote, "Thank you both for getting the company out of an impossible situation. This is the right path...  I believe it with all my heart."

Besides, because of the ever-changing international situation, the supply and prices of international bulk Nitinol are still very uncertain.
