Yield strength (austenite) 195–690 MPa (28.3–100.1 ksi) (martensite) 70–140 MPa (10–20 ksi) Poisson's ratio: 0.33: Nitinol properties are particular to the precise composition of the alloy and its processing. These specifications are typical for commercially available shape memory nitinol alloys
Nitinol biocompatibility is an important factor in biomedical applications. Nitinol (NiTi), which is formed by alloying nickel and titanium (~ 50% Ni), is a shape-memory alloy with superelastic properties more similar to that of bone, [ clarification needed ] when compared to stainless steel , another commonly used biomaterial .
NiTiNOL 60, or 60 NiTiNOL, is a Nickel Titanium alloy (nominally Ni-40wt% Ti) discovered in the late 1950s by the U. S. Naval Ordnance Laboratory (hence the "NOL" portion of the name NiTiNOL). [1] Depending upon the heat treat history, 60 NiTiNOL has the ability to exhibit either superelastic properties in the hardened state or shape memory ...
The most common side-effects are mild skin irritations, redness and flaking. [9] The United States Food and Drug Administration (FDA) and Cosmetic Ingredient Review expert panels both suggest that alpha hydroxy acids are safe to use as long as they are sold at low concentrations, pH levels greater than 3.5, and include thorough safety instructions.
The R-phase is a phase found in nitinol, a shape-memory alloy. It is a martensitic phase in nature, but is not the martensite that is responsible for the shape memory and superelastic effect. In connection with nitinol, "martensite" normally refers to the B19' monoclinic martensite phase, rather than the R-phase. The R-phase competes with ...
The two most prevalent shape-memory alloys are copper-aluminium-nickel and nickel-titanium (), but SMAs can also be created by alloying zinc, copper, gold and iron.Although iron-based and copper-based SMAs, such as Fe-Mn-Si, Cu-Zn-Al and Cu-Al-Ni, are commercially available and cheaper than NiTi, NiTi-based SMAs are preferable for most applications due to their stability and practicability [1 ...
Topical steroids are the topical forms of corticosteroids.Topical steroids are the most commonly prescribed topical medications for the treatment of rash and eczema.Topical steroids have anti-inflammatory properties and are classified based on their skin vasoconstrictive abilities. [1]
It is a cream that is used for muscle and joint pains including osteoarthritis, strains, bruises, and sprains. [1] The active ingredient is menthol [ 2 ] and it also contains cetylated and esterified fatty acids .
