Nitinol – Metallic Muscles with Shape Memory


From the Author: So today I will tell you about one unusual object - the paper clip. This clip is made from a very unusual material - nitinol. Nitinol is an alloy of nickel and titanium in proportions of 45% titanium and 55% nickel. This alloy has the unique property that was discovered in 1961 by American scientists. The property of this alloy is called "shape memory". So to demonstrate this property let’s conduct an experiment.
