It is important to minimize the density of all materials in electric aircraft, which includes materials selected for structural and electrical conductor components. Thus, aluminum (Al) alloys are chosen for the airplane skin and many of the internal support members. Pure Al has two key advantages for use as the prime electrical conductor: low density and good electrical conductivity. At...

Ultrahigh conductivity Al (Al hyperconductors, RRR ~10^4) has the capacity to be competitive with superconductors at cryogenic temperatures. High-purity Al (HPAL) conductivity has the benefits of not being dependent on a transition temperature, Tc, allowing for a wider range of operational temperatures, and has lower ohmic heating contributions than superconductors in high-frequency bands....

Ferrite and austenite duplex stainless steels exhibit an excellent strength-ductility balance at low temperatures. On the other hand, it is well known that grain refinement improves not only the strength but also the toughness of metal materials. In this study, the effects of grain size on the low-temperature tensile properties in ferrite and austenite duplex stainless steel having different...

The austenitic stainless steels, such as type 304L (18Cr-9Ni, mass%) and 316L (16Cr-10Ni-2Mo), are widely used in cryogenic applications. However, their strength is relatively low, and the martensitic transformation appears when they are strained at low temperature. For structural applications at 4.2 K, therefore, type 316LN (17Cr-11Ni-2Mo-0.2N) nitrogen-strengthened austenitic stainless steel...

In this paper, real-time strain monitoring of epoxy resin and glass fiber reinforced composites was explored using embedded FBG from curing process to high temperature (413 K), cooling down to cryogenic temperature (4.2 K), and three-point bending experiment. The experimental data tested by FBG was compared with results got by strain gauges and extensometers. It was found that trend of strain...
