SHAPE MEMORY ALLOYS - Phase, Types, Characteristic, Application

A group of metallic alloys which shows the ability to return to their original shape or size i.e., alloy appears to have memory when they are subjected to heating or cooling are called shape memory alloys. See full list on Martensite and austenite are two solid phases in SMA as shown in fig. Fig. Phases of SMA Martensite is relatively soft and it is easily deformable phase which exists at low temperature (monoclinic). (i) Austenite is a phase that occurs at high temperature having a crystal structure and high degree of symmetry (cubic). See full list on There are two types of shape memory alloys (i)One-way shape memory alloy (ii)Two-way shape memory alloy A material which exhibits shape memory effect only upon heating is known as one-way shape memory. A material which shows a shape memory effect during both heating and cooling is called two-way shape memory. Examples of shape memory alloys Generally, shape memory alloys are intermetallicpounds having super lattice structures and metallic-ionic-covalent characteristics. Thus, they have the properties of both metals and ceramics. Ni –Ti alloy (Nitinol) Cu –Al –Ni alloy Cu –Zn –Al alloy Au –Cd alloy Ni –Mn –Ga and Fe based alloys See full list on The change of shape of a material at low temperature by load regaining of original shape by heating it, is known as shape memory effect. The shape memory effect occurs in alloys due to the change in their crystalline structure with the change in temperature and stress. While loading, twinned martensite bes deformed martensite at low temperature. On heating, deformed martensite bes austenite (shape recovery) and upon cooling it gets transformed to twinned martensite (fig.). SMAs exhibit changes in electrical resistance, volume and length during the transformation with temperature. The mechanism involved in SMA is reversible (austenite to martensite and vice versa.) 1. Stress and temperature have a great influence on martensite transformation. 2. Pseudo elasti Pseudo –elasti occurs in shape memory alloys when it ispletely in austenite phase (temperature is greater than Afaustenite finish temperature). Unlike the shape memory effect, Pseudo-elasti occurs... See full list on The only two alloy systems that have achieved any level ofmercial exploitation are, (i) Ni-Ti alloys, and (ii) Copper base alloys. Properties of the two systems are quite different. The basis of the Nickel-Titanium alloy is tnary, equi-atomic inter-metallicpound of Ti-Ni. The inter-metallicpound is extraordinary because it has moderate solubility range for excess Nickel or Titanium, as well as most other metallic elements. This solubility allows alloying with many of the elements to modify both the mechanical properties and the transformation properties of the system. Excess Nickel strongly depresses the teases the yield strength of the austenite. The contamits such as Oxygen and Carbon shift the transformation temperature and degrade the mechanical properties. Therefore, it is also desirable to minimize the amount of such elements. See full list on They are simple,pact and high safe. They have good bio patibility. They have diverse applications and offer clean, silent and spark-free working condition They have good mechanical properties and are strong corrosion-resistant. See full list on One of the mostmon applications of SMAs is mocrovalves. Fig. shows a microvalve made of Ni –Ti alloy actuator. Actuator is a microsensor that can trigger the operation of a device. The electrical signal initiates an action. Fig. Schematic of microvalves that open and close according to temperature When an electrical current of 50 to 150 mA flows in Ni-Ti actuator, it contracts and lifts the poppet from the orifice and opens the valve.

(i) Blood clot filters are SMAs, properly shaped and inserted in veins to stop the passing blood clots. When the SMA is in contact with the clot at a lower temperature, it expands and stops the clot and blood passes through the veins. (ii) They are used in artificial hearts.
