Bulk metallic glasses (BMGs) bear versatile advantages compared to traditional crystalline materials. However, preparation of large size BMG components remains a great challenge due the lack understanding casting dynamics BMGs. The present work investigates solidification process during Zr41.2Ti13.8Cu12.5Ni10Be22.5 by measuring time-dependent temperature evolution and constructing distance–time curves showing progress solidification. experimentally probed proves that higher causes lower...

In order to fulfill the working requirements within some specific space, this paper proposes design and optimization method for redundant flexible cable-driven robot. According relevant restrictions robot's structure, distributed flexible-cable driving strategy investigated with focus on minimizing maximum tension every cable. Through symmetry group physical group, both search task computational cost are...
Abstract Induction skull melting (ISM) technology could melt metals with avoiding contamination from crucible. A long-standing problem of ISM is that the low charge energy utilization and inhomogeneous fields have obstructed its application in many critical metal materials manufacturing processes. The present work investigated through structure optimization strategy established a numerical electromagnetic-field model to evaluate components’ eddy current loss. Based on model, effect crucible...
Herein, the ordered structure of Co-based metallic microwires was modulated by direct current-annealing, thereby improving tensile mechanical properties. Based on thermophysical parameters microwires, annealing current intensities 65 mA, 90 mA and 150 were determined method numerical calculation.

Underwater wireless optical communications (UWOCs) use beam shaping techniques such as the Beer-Lambert (BL) law which describes how light interacts with matter. The BL model ignores scattering effect of UWOC, while spread function (BSF) can characterize combined absorption and UWOC more accurately. original triple-integral (OTI-BSF) involves Bessel function, is very time-consuming to calculate. In addition, different seawater environments may require phase functions (SPFs) obtain accurate...
Multiferroic Bi1−xCaxFeO3−x/2 (0.10 ⩽ x 0.50) materials have been synthesized via a high-temperature sintering method. The structural properties studied using transmission electron microscopy (TEM), scanning (STEM) and energy loss spectroscopy (EELS).
