Why Nickel titanium alloy powder Is a Shape Memory Alloy
What is Nickel titanium alloy powder?
Nickel titanium alloy powder, as a new functional material integrating noticing and driving, is an essential member of intelligent material structure and has considerable theoretical and application research worth Ti-Ni shape memory alloy is a sort of practical material with high strength, deterioration resistance, excellent biocompatibility, non-toxic, and medical application prospects. After the low-temperature phase is deformed, it can restore the shape remembered by the parent stage only by adding a temperature of 20 ~ 300 ℃. Its expansion rate is more than 20%, fatigue life reaches 107 times, damping qualities are ten times greater than regular springs, and it has residential or commercial properties that typical metals can not envision. For that reason, it is commonly used in stomatology, orthopedics, and many other medical fields. In the last few years, titanium nickel memory alloy has actually been irreplaceable in treating different fractures.
Application of nickel-titanium alloy powder Nickel titanium alloy powder is generally utilized to make spacecraft self-deployable antennae by benefiting from the shape memory function of nickel-titanium alloy powder. In addition, nickel-titanium alloy powder is a shape memory alloy. Forming memory is that when the parent stage of a particular shape cools from above a specific temperature level to below a particular temperature, its metallography (metal crystal structure) modifications. However, this phase improvement is reversible. When it is again at a specific temperature, the metallography differs inversely. The shape memory impact 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. Forming memory alloy is a special alloy that can automatically restore its plastic contortion to its initial shape at a particular 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 an area as little as every square millimeter, which is more powerful than normal steel and has great "memory" efficiency and deterioration 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 flexible limit pressure under the action of external force. The music can recuperate automatically when dumping. Under the parent phase state, the stress-induced martensite phase modification happens due to the result of external stress, so the alloy reveals a mechanical habits different from that of regular materials. Its elastic limit is far greater than typical materials and Hooke'' s Law is no longer obeyed. Compared to shape memory qualities, Hyperelasticity does not include heat. In a word, Hyperelasticity means that the tension does not increase with the increase of stress within a particular deformation variety; Hyperelasticity can be divided into direct Hyperelasticity and nonlinear Hyperelasticity. The former has a nearly direct relationship in between stress and stress and anxiety in the stress-strain curve. Nonlinear Hyperelasticity refers to the results of stress-induced martensitic improvement and its reverse improvement throughout loading and discharging in a specific temperature level range above Af. For that reason, nonlinear Hyperelasticity is also called improvement pseudoelasticity. The improvement 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 up to more than 400oC, the Hyperelasticity starts to decrease.
