Abstract
The effects of the cooling rate, after solution heat treatment, on the microstructures and mechanical properties of Fe-22Mn-8Al-0.8C-0.02Nb (low carbon) and Fe-20Mn-8Al-1.1C-0.1Nb (high carbon) light-weight steels were systematically investigated. The cooling process was controlled to achieve six different cooling rates, ranging from -0.016 to -465.1 ^oC/s. Under the slowest cooling..... More

Abstract
A superelastic titanium alloy was subjected to uniaxial tensile deformation at room temperature. The microstructural evolution and deformation mechanisms of the superelastic titanium alloy were investigated by electron backscatter diffraction (EBSD) and X-ray diffraction (XRD). Multiple deformation mechanisms including stress-induced martensitic transformation (SIMT), dislocation slip, {332}<113> and {112}<111> mechanical twinning..... More

Abstract
The effects of cooling after solution heat treatment on the microstructure and mechanical properties of light-weight steels were investigated using Fe^-30Mn^-xAl^-0.9C alloys containing 9.0–12.8 wt% Al. Lab^-scale specimens (thickness: 10 mm) of the alloys were cooled by different cooling rates from -337 to -0.053 ℃/s using water, air, and furnace..... More

Abstract
Aluminum conductors are increasingly replacing copper because Al has lower cost and lighter weight, and consequently the demand for Al-Cu joints for industrial applications is growing. However, an intermetallic compound is known to grow at the Al-Cu interface, and will result in fracture if it grows above a critical thickness...... More
