Session on Shape Memory Alloys & Shape Memory Polymers at Smart Materials Congress 2020,Amsterdam on May 25-26,2020
Shape
Memory Alloys have mostly two
phases Austenite and Martensite. Austenite phase
is symmetric and Martensite phase
is less symmetric. When a SMA is in martensite phase at lower temperatures, the
metal can be deformed easily into any shape. When the alloy is warmed, it
goes through transformation from martensite to austenite. Shape
memory alloys are special and unique class of metal
alloys when warmed up above certain temperature can recuperate apparent
lasting strains which are resulted in it. They have high strength, good
elasticity, fatigue resistance, wear resistance, easy fabrication.
SMA’s have the ability to be used successfully in seismic area.
The
two most prominent shape-memory alloys are copper-aluminum-nickel and
nickel-titanium (NiTi), but SMAs can also be developed by alloying zinc,
copper, gold and iron.
Shape-memory
polymers (SMPs) are polymeric smart materials that have the
ability to return from a deformed state (temporary shape) to their
permanent shape develop by an external stimulus, such as temperature
change. Shape Memory polymers are the compound plastics polymers that
have a unique chemical structure. The glass transition temperature (Tg) plays a
crucial role in Shape
Memory Polymers. Above the Tg these Shape Memory polymers turn
into rubber elastic and flexible. These Materials can solve engineering
problems with unbelievable efficiency.
Here
are the examples of polymers which can exhibit shape
memory effect include(meth)acrylates, polyurethanes,
and blends of polyurethane and polyvinylechloride.
