What is Nickel titanium alloy powder? Nickel titanium alloy powder, as a new functional material integrating sensing and driving, is an essential member of intelligent material structure and has significant theoretical and application research value Ti-Ni shape memory alloy is a kind of functional material with high strength, corrosion resistance, good biocompatibility, non-toxic, and medical application prospects. After the low-temperature phase is deformed, it can restore the shape memorized by the parent phase only by adding a temperature of 20~300 ℃. Its expansion rate is more than 20%, fatigue life reaches 107 times, damping characteristics are ten times higher than ordinary springs, and it has properties that common metals cannot imagine. Therefore, it is widely used in stomatology, orthopedics, and many other medical fields. In recent years, titanium nickel memory alloy has been irreplaceable in treating various fractures.
Application of nickel-titanium alloy powder Nickel titanium alloy powder is usually used to make spacecraft self-deployable antennae by taking advantage of the shape memory function of nickel-titanium alloy powder. In addition, nickel-titanium alloy powder is a shape memory alloy. Shape memory is that when the parent phase of a specific shape cools from above a certain temperature to below a particular temperature, its metallography (metal crystal structure) changes. However, this phase transformation is reversible. When it is again at a specific temperature, the metallography varies inversely. The shape memory effect is a heat-induced phase transformation process of Ni-Ti alloy.
Strength of nickel-titanium alloy powder Nickel titanium alloy powder is a shape memory alloy. Shape memory alloy is a special alloy that can automatically restore its plastic deformation to its original shape at a specific temperature. It has good plasticity. The tensile strength of nickel titanium alloy powder can reach 1000 MPa That is to say, it takes more than 100 dry grams of force to break a section as small as every square millimeter, which is stronger than ordinary steel and has good "memory" performance and corrosion resistance.
Superelasticity of Nickel titanium alloy powder The so-called superelastic refers to the phenomenon that the specimen produces a strain far greater than the elastic limit pressure under the action of external force. The music can recover automatically when unloading. Under the parent phase state, the stress-induced martensite phase change occurs due to the effect of external stress, so the alloy shows a mechanical behavior different from that of ordinary materials. Its elastic limit is far greater than common materials and Hooke's Law is no longer obeyed. Compared with shape memory characteristics, Hyperelasticity does not involve heat. In a word, Hyperelasticity means that the stress does not increase with the increase of strain within a specific deformation range; Hyperelasticity can be divided into linear Hyperelasticity and nonlinear Hyperelasticity. The former has a nearly linear relationship between stress and anxiety in the stress-strain curve. Nonlinear Hyperelasticity refers to the results of stress-induced martensitic transformation and its reverse transformation during loading and unloading in a specific temperature range above Af. Therefore, nonlinear Hyperelasticity is also called transformation pseudoelasticity. The transformation pseudoelasticity of nickel-titanium alloy can reach about 8%. The Hyperelasticity of nickel-titanium alloy can change with heat treatment conditions. When the archwire is heated to more than 400oC, the Hyperelasticity begins to decline.
