Children will investigate the energy-generating properties of a solar cell, a radiometer, a Nitinol heat engine, and a Peltier cell--there are even plans to build a human-powered desk lamp. The thermodynamics of NITINOL Heat Engines was examined from the viewpoints of both theory and application. ) A strait piece of nitinol wire was distorted by bending, twisting, or whatever the audience chose to do. For example, unlike most other metal alloys, which expand when heated, Nitinol contracts. Alfred Johnson who was granted a patent on this type of heat engine in 1977 patent # 4,055,955. Nitinol Heat Engine. Nitinol has trained into a shape at high temperature (about 600° C) and allowed to cool to room temperature, where it can be easily deformed and welded into a loop. It's possible to build an engine with compressed gas alone, without the heat, but it wouldn't be a complete cycle without some way to compress the gas again. Nitinol Strip & Foil (Rolled from Flat Wire), ASTM F2063 (Chemistry) Nitinol (NiTi) Applications. [3][4] William Buehler was attempting to make a better missile nose cone, which could resist fatigue, heat and the force of impact.
