Shape-memory alloy - Wikipedia
In metallurgy, a shape-memory alloy (SMA) is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated. It may also be called memory metal, memory alloy, smart metal, smart alloy, or muscle wire. Parts made of shape-memory alloys can be lightweight, solid-state … Visa mer The two most prevalent shape-memory alloys are copper-aluminium-nickel and nickel-titanium (NiTi), but SMAs can also be created by alloying zinc, copper, gold and iron. Although iron-based and copper-based SMAs, such as Visa mer Shape-memory alloys have different shape-memory effects. The two common effects are one-way SMA and two-way SMA. A schematic of … Visa mer The first reported steps towards the discovery of the shape-memory effect were taken in the 1930s. According to Otsuka and Wayman, Visa mer Shape-memory alloys are typically made by casting, using vacuum arc melting or induction melting. These are specialist techniques used to keep impurities in the alloy to a minimum … Visa mer The shape memory effect (SME) occurs because a temperature-induced phase transformation reverses deformation, as shown in the … Visa mer SMAs display a phenomenon sometimes called superelasticity, but is more accurately described as pseudoelasticity. “Superelasticity” implies that the atomic bonds between atoms stretch to an extreme length without incurring plastic deformation. … Visa mer Many metals have several different crystal structures at the same composition, but most metals do not show this shape-memory effect.
