    摘要： A heat transport system includes a fluid, a heat engine, and a component. The fluid has a first fluid region at a first temperature and a second fluid region at a second temperature that is different from the first temperature. The heat engine includes a shape-memory alloy disposed in contact with each of the first fluid region and the second fluid region. The heat engine is operable to transfer heat from one of the first fluid region and the second fluid region to the other of the first fluid region and the second fluid region in response to the crystallographic phase of the shape-memory alloy.

    摘要： A method of starting a heat engine includes exposing an element of the heat engine to a source of thermal energy provided by a temperature difference between a heat source having a first temperature and a heat sink having a second temperature that is lower than the first temperature. The element is formed from a first shape memory alloy having a crystallographic phase changeable between austenite and martensite at a first transformation temperature in response to the temperature difference between the heat source and the heat sink. The method further includes changing the crystallographic phase of the first shape memory alloy to thereby convert thermal energy to mechanical energy, and inducing initial movement of the element in a desired operational direction to thereby start the heat engine.

    摘要： A device is provided that may be adapted to control or monitor the pressure level of a fluid system. The device includes a member composed of a shape memory alloy in a superelastic state. The member is configured to undergo a phase change from a high modulus Austenitic phase to a low modulus Martensitic phase and stretch in response to an activation stress. In one embodiment, the member defines two ends such that one end of the member is operatively connected to a fixed point. Another end of the member is operatively connected to a movable element. As the member stretches in response to the activation stress, the movable element is translated relative to the fixed point. In another embodiment, the member includes two plates with respective holes that are selectively aligned when the first and second plates stretch or deform in response to the activation stress.
