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 the effects is shown below. Visa mer The first reported steps towards the discovery of the shape-memory effect were taken in the 1930s. According to Otsuka and Wayman, Arne Ölander discovered the … 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 and ensure the metals are well mixed. The ingot is then hot rolled into longer sections … 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 … Visa mer Many metals have several different crystal structures at the same composition, but most metals do not show this shape-memory effect. The special property that allows shape-memory alloys to revert to their original shape after heating is that their crystal … Visa mer Webb형상기억합금(形狀記憶合金, Shape-memory alloy)이란 다른 모양으로 변형시키더라도 가열에 의하여 다시 변형 전의 모양으로 되돌아오는 성질을 가진 합금을 말한다.예를 들면 곧게 뻗은 형상기억합금의 막대를 코일 모양으로 구부려 놓는다. 얼마 있다가 더운물에 넣으면 마치 이전의 모양을 기억하고 ...
