Numerical simulation of the internal stress of Fe–Si–B amorphous alloy ribbons prepared by planar flow casting

Lijun Li, Deren Li, Menghua Xun, B Li et autres

Abstract Internal stress generated during the rapid cooling and solidification of the melt is one of the key factors that deteriorate the magnetic properties of amorphous ribbons produced by planar flow casting (PFC). In this study, a two-dimensional thermo-mechanical coupling model was …

A Numerical Study on Molten Pool Behavior and Ribbon Thickness Under Varying Casting Parameters in Planar Flow Casting

Lijun Li, Jianliang Sun, Hongxin Ji, Deren Li et autres

Despite the widespread use of planar flow casting (PFC) for amorphous alloy ribbons, previous two-dimensional (2D) numerical studies have primarily focused on isolated flow or thermal behaviors, lacking a systematic quantification of how key casting parameters collectively influence melt puddle geometry and …

Numerical and Experimental Study on the Molten Pool Behavior and Magnetic Properties of Nano-Crystalline Alloy Ribbon Prepared by PlanarFlow Casting

Lijun Li, Hongxin Ji, Jian Sun, Deren Li et autres

A 2D multiphase-flow coupling simulation model for preparing nanocrystalline ribbons using planar-flow casting (PFC) with a cooling roller was established. The influence of roller speed on molten pool characteristics, cooling-roller heat transfer, and ribbon thickness was analyzed. The effect of ribbon thickness …

Knowledge-based land use dynamic monitoring supported by the ‘3S’-integration technique

Changsheng Xue, Qingquan Li, Deren Li, Bijun Li

The New National Land and Resources Investigation Project in China was launched in 1999, and anticipated to last 12 years. Land use dynamic monitoring is an important part of this grand, cross-century project. In this paper, the general structure and technical approach …

Case Report: Prenatal diagnosis of a rare complex fetal karyotype 47,U,t(10;13)(p15;q22)mat,+der(13)t(10;13)dmat resulting from 3:1 meiotic segregation of a maternal balanced translocation

Guangsheng Deng, D. H. Zhang, Yancheng Lai, J. J. Song et autres

Objective: To characterize a rare fetal complex chromosomal rearrangement (CCR) derived from a maternal balanced translocation using integrated G-banding and CNV-seq analysis. Methods: Integrated G-banding and CNV-seq enabled precise karyotypic determination in the fetus, with familial verification confirming its derivation. Results: Karyotype …

Semantic-centric change detection framework: considering spatiotemporal heterogeneity and spatiotemporal correlation of land cover

Shasha Hou, Hao Cui, Xue Li, Yujia Chen et autres

The semantic change detection (SCD) task aims to detect ‘from-to’ change types of land cover occurring over time in registered bitemporal remote sensing images. The spatiotemporal heterogeneity of land cover introduces significant intra-class variance, whereas spatiotemporal correlation provides a reference for land …
