Abstract: A membrane actuator includes a magnetically actuatable membrane and a magnetic trigger. The membrane includes a shape memory alloy (SMA), and the magnetic trigger is configured to induce a martensitic transformation in the SMA, to produce a larger force than would be achievable with non-SMA-based materials. Such a membrane actuator can be beneficially incorporated into a wide variety of devices, including fluid pumps, shock absorbing systems, and synthetic jet producing devices for use in an aircraft. The membrane/diaphragm can be formed from a ferromagnetic SMA, or a ferromagnetic material can be coupled with an SMA such that the SMA and the ferromagnetic material move together. A hybrid magnetic trigger, including a permanent magnet and an electromagnet, is preferably used for the magnetic trigger, as hybrid magnetic triggers are easy to control, and produce larger magnetic gradients than permanent magnets or electromagnets alone.

Abstract: An aluminum casting alloy consisting of, by weight, of 7.0-13.0% copper, 0.4-1.2% manganese, 0.21-40% vanadium, 0.31-0.70% zirconium; impurities limited to: less than to 0.6% Si, less than 0.8% Fe, less than 0.2% zinc, less than 0.1% Mn, less than 0.2% Ni, and the remainder being essentially aluminum. There is an absence of titanium, cobalt, molybdenum, tungsten, chromium, boron, tantalum, and niobium. The alloy has, at room temperature, a UTS of about 61 ksi, a YS of about 49 ksi, a tensile elongation of about 6%, and tensile modulus elasticity of about 11.5 MSI, a compressive yield strength of about 53 ksi, a compressive modulus of elasticity of about 18 MSi; high temperature physical properties at 500.degree. F., after 1000 hours exposure to 500.degree. F., comprise a tensile strength of 33 ksi or greater, a tensile yield strength of 23 ksi or greater, a tensile elongation of about 9%, and tensile modulus of elasticity of 10 msi. The alloy is fabricated by a) squeeze casting an aluminum alloy melt of such character; (b) extracting the solidified casting from the die and heat treating the casting to dissolve all alloying elements (i.e., 995.degree.-1018.degree. F. for 7-20 hours); and (c) aging the solution treated casting to achieve improved strength characteristics (i.e., in the range of 340.degree.-400.degree. F. for 5-20 hours).
