128. M3Or4M-02: [Invited] Strength of Pure Al at Cryogenic Temperatures

Karl Hartwig

Invited Oral

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...

498. M3Or4M-03: [Invited] Resistivity ratios for high purity aluminum in magnetic fields

Jin Kwon

Invited Oral

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....

68. M3Or4M-04: [Invited] Tensile properties and deformation behavior at low temperatures in ferrite and austenite duplex stainless steel with various grain sizes

Dr Norimitsu Koga (Kanazawa University)

7/12/23, 4:55 PM

Invited Oral

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...

307. M3Or4M-05: [Invited] Strength and Fracture Toughness of Type 304 and 316 Austenitic Stainless Steels at 4.2 K

Dr Yoshinori Ono (National Institute for Materials Science)

7/12/23, 5:10 PM

Invited Oral

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...

188. M3Or4M-06: [Invited] Three-point bending experiment of epoxy resin and glass fiber reinforced composites by Fiber Bragg Gratings

Di Jiang

Invited Oral

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...
