Nitinol (Nichel Titanium Naval Ordnance Laboratory)

Nitinol HistoryAlthough scientists have known about and experimented with SMA's since 1932, it wasn't until 1962 that the materials came out of the laboratory. William Beuhler, working at the US Naval labs, discovered the SMA effect in an alloy of nickel and titanium. At the time the scientific team were trying to develop a heat and corrosive resistant alloy. In the process of creating a corrosive resistant alloy, they created a Shape Memory Alloy (SMA) made of 55% nickel and 45% titanium. This new material was relatively inexpensive and much safer (non-toxic) than previous SMA's.
The team named their new alloy Nitinol (pronounced night-in-all). The name represents its elemental components and place of origin. The "Ni" and "Ti" are the atomic symbols for nickel and titanium.
The "NOL" stands for the Naval Ordnance Laboratory where it was discovered.Fonte Cita:
The Naval Ordnance Laboratory (NOL), now disestablished, formerly located in White Oak, Maryland
was the site of considerable work that had practical impact upon world technology. The White Oak site of NOL has now been taken over by the Food and Drug Administration.

White Oak
In 1944, acquisition, planning and construction work began at a 712-acre (2.88 km2) wooded site located at 10903 New Hampshire Avenue, Silver Spring, Maryland. Someone remarked to a Navy official during early 1945 that it seemed odd to be building the new laboratory at that time:
the war would probably be over before the facility could be finished. "That laboratory" remarked the Navy man, "is not being built for this war".[1]
