adminNitinol can be used as a shape memory alloy. This is a unique alloy that has the ability to automatically return its plastic deformation back to its original form at a specific temperature. It also has excellent plasticity.
Apart from their unique shape memory feature, memory alloys offer excellent properties such as corrosion resistance, wear resistance, and high damping.
1.What Is the Performance of Nitinol
The name nickel-titanium alloy powder refers to a binary powder that is made up of titanium and nickel. Two crystal phases are formed by temperature and pressure changes. These two phases are austenite phase or martensite. It is called parent phase, R phase and martensite phases in the nickel-titanium alloy cooling phase. The R phase, which is rhombohedral and austenite when it is heated or is under load, is hard. This shape is very stable. Martensite is stable at low temperatures and under loading. It is hexagonal in shape, repeatable and stable, with easy deformation.
2.What are the special properties of Nitinols?
Form memory properties: Form memory refers to when the parent phase of an object is subcooled to below Mf temperature. The martensite then is heated below Mf and deformed. It will restore the material’s original form in its parent phase.
Superelasticity A phenomenon known as superelasticity is when a sample creates a strain that exceeds its elastic limit under external forces. The strain then can recover automatically when it’s unloaded.
Temperature changes in the dental cavity can affect the sensibility of orthodontic wires made from stainless steel and CoCr alloy. However, the temporal cavity temperature does not impact the orthodontic power.
The corrosion resistance of Nickel-Titanium Wire: Research has shown that it is comparable to the resistance of stainless steel.
Anti-toxicity. Nitinol form memory alloy contains a particular chemical composition. This is because it has an atomic alloy such as Nitinol. Nitinol is known for having carcinogenic or cancer-promoting properties.
Gentle orthodontic power: currently commercially used orthopedic wires include austenitic stainless steel wires, cobalt-chromium-nickel alloy wires, nickel-chromium alloy wires, Australian alloy wires, gold alloy wires and nickel-titanium alloy wires.
High shock absorption: More vibrations from chewing, night molars and other activities can cause damage to the roots and periodontal tissue.
