Effect of Rapid Solidification on the Structure and Phase Composition of Mg-Al-Zn, Mg-Nd-Zr, and Mg-Li-Al Alloys

期刊: RUSSIAN METALLURGY, 2021; 2021 (6)

Metallographic and X-ray diffraction analyses are used to study the effect of rapid solidification (RS) by pendant melt drop extraction (PMDE) on the ......

Microstructure of Graphitized Steel during Warm Compression

期刊: RUSSIAN METALLURGY, 2021; 2021 (1)

A Gleeble 3500 physical modeling complex is used to deform graphitized steel (0.46% C) with a microstructure mainly consisting of ferrite and graphite......

Welch bound-achieving compressed sensing matrices from optimal codebooks

期刊: DISCRETE MATHEMATICS ALGORITHMS AND APPLICATIONS, 2020; 12 (3)

Compressed sensing (CS) is a new data acquisition theory taking full use of the sparsity of signals. It reveals that higher-dimensional sparse signals......
