Micro-scale strain distribution in hot-worked duplex stainless steel [PDF]
, 2005 A modified microgrid technique has been applied to a laboratory-made duplex stainless steel, to experimentally simulate the local state of deformation of the austenite-ferrite microstructure of low-alloy steels subject to intercritical deformation.

Development of the Metal Rheology Model of High-temperature Deformation for Modeling by Finite Element Method [PDF]
, 2019 It is shown that when modeling the processes of forging and stamping, it is necessary to take into account not only the hardening of the material, but also softening, which occurs during hot processing.

The effect of rare earth elements on the work softening behavior of as-cast Mg-4Al-2Sn
Materials Research Express, 2020 This work explores the addition of 1% Rear Earth (RE) elements on the Mg–4Al–2Sn magnesium alloy, with an emphasis laid on the microstructural evolution during solidification and subsequent hot deformation behavior.

基于定点形变资料获取断裂浅层倾向和倾角的方法研究—以唐山台为例
Dizhen xuebao, 2018 本文利用唐山地震台1978—2016年跨断层定点形变资料探究唐山地震台所跨断层的浅层倾向和倾角。首先，对形变资料进行数字滤波处理，消除原始观测数据中的非构造信息；其次，对数据精度进行评价，得出1997—2016年滤波后的形变数据年累计残差普遍较小、精度较高；最后，采用精度较高的形变数据计算SE和NW两倾向不同倾角下基线与水准和的累计残差分布，进而获取断层的浅层倾向和倾角。结果显示，依据跨断层定点形变资料获得唐山地震台所跨断层的浅层倾向为SE，倾角为89°，该结果与前人探槽剖面中断层产状相一致 ...

Journal of Materials Research and Technology, 2023 The electrical properties of polymer materials, such as electrical conductivity and piezoelectricity, are significantly influenced by the ratio of amorphous to crystalline regions. Additionally, the alignment of added particles and formed crystallites is

No Self-Interaction for Two-Column Massless Fields [PDF]
, 2004 We investigate the problem of introducing consistent self-couplings in free theories for mixed tensor gauge fields whose symmetry properties are characterized by Young diagrams made of two columns of arbitrary (but different) lengths.
